Concrete Curing Time

Waiting for the curing of concrete can easily test patience, especially when you’re ready to move on to the next step of a project. However, it’s important to remember that quality is the end goal, not quickness. Rushing ahead and not allowing enough time for concrete to properly cure before allowing foot traffic or heavy machinery to travel across your newly placed cement can seriously compromise the integrity of a concrete slab.

 

Cement Curing Factors

Several factors influence concrete slab cure time, including:

 

Typical Concrete Setting Time

Typically, concrete is recognized to have reached full strength 28 days after placement; however, this does not mean you need to wait 28 days to walk, or even continue construction on newly placed concrete. After placement, concrete increases in strength very quickly for 3-7 days, then gradually for the next 3 weeks. This means that concrete hardening time is typically 24-48 hours, at which point it’s safe for normal foot traffic. After one week, concrete is typically cured enough to handle continued construction including heavy machinery.

The “70 in 7” Rule

When in doubt, remember the “70 in 7” rule: Most concrete mixes will have reached 70% of specified compressive strength after 7 days. At this point, it’s ready for exposure to normal traffic.

Concrete Curing Blankets

Unfortunately, cold weather during winter months can seriously slow down concrete cure time and significantly hold up construction projects. Luckily, solutions, such as concrete curing blankets that maintain optimum temperatures during cure time, are available. Concrete Blankets are an effective option that cure concrete 2.8 times faster than a typical insulated blanket and properly maintain moisture throughout the hydrating process. Concrete Blankets are easily transported and installed and maintain ACI compliance for cold-weather concreting.

The Association for Manufacturing Excellence (AME) today announced four recipients of the AME 2017 Excellence Award. The AME Excellence Award primarily recognizes North American manufacturing plants that have demonstrated excellence in manufacturing and business. The award acknowledges continuous improvement, best practices, creativity and innovation. Recognized among those four recipients is Powerblanket, the smallest company ever to receive this award.

Powerblanket – Salt Lake City, Utah

The leader in total temperature control, Powerblanket designs and manufactures high technology smart controls and monitoring devices, heating blankets, and chilling products that solve a wide range of temperature problems in industries such as oil and gas, construction, industrial, mining, and railroad. The AME assessment team highlighted Powerblanket’s great culture throughout the company. The team also commended Powerblanket’s improvements and impressive turnaround, especially for only being three years into its lean journey. The award presentation will take place on Oct. 25, 2017.

How It All Started

Powerblanket is a great example of problem solving and innovation in industry. A concrete worker in Salt Lake City, UT wanted to work more efficiently year-round. He worked with an engineering professor at the University of Utah to create an efficient heating technology that would cure concrete quickly and with maximum strength. They developed an innovative concrete heating product and founded Powerblanket, which soon became a leading manufacturer in the concrete industry.  This technology proved to solve many temperature problems for applications across many different industries, and they began wrapping barrels, buckets, pipes, and tanks. From there they developed an expertise in temperature control, built a world-class custom design team, created control devices, and entered the industrial cooling industry with a new line of chillers and cooling blankets.

What started as a solution to a common constructi

on problem, has turned into an industry-leading company that engineers and manufactures temperature control solutions for many different industries all over the world.

More About the AME Award

The AME Excellence Award has a rigorous selection process that begins when a company submits an extensive achievement report based on the AME Excellence Award evaluation criteria. Achievement reports are evaluated by the AME award assessment team. For companies that score high enough in this achievement report review, an intensive site visit is completed, during which a volunteer team of manufacturing practitioners validates the submitted achievement report. Recipients of the Excellence Award are selected based on the combined results of the achievement report review and site visit feedback.

The AME Excellence Award is not something that can be achieved by one person or one company leader. It takes all team members working together to achieve the level of enterprise excellence that the AME Excellence Award recognizes. With that in mind, AME representatives will visit award recipients’ facilities to present awards in person so that everyone working in these facilities can participate in the celebration.

How Cold is Too Cold to Pour Concrete?

What Temperature is Too Cold to Pour Concrete?

Experts agree that the best temperature to pour concrete is between 50-60 °F. The necessary chemical reactions that set and strengthen concrete slow significantly below 50 °F and are almost non-existent below 40 °F. Even when daytime temperatures are within the satisfactory range, winter concrete setting creates risks that could result in weak, inadequate concrete. If nighttime temperatures are below freezing, the water in the concrete will freeze and expand, causing cracks. Additionally, if temperatures reach below 40 °F (but not freezing) during set time, concrete will take much longer to reach required strength. However, if the correct measures are taken, concrete can still be successfully placed during even the coldest months of the year.

Things to Consider with Cold Weather Concreting

Before embarking on a cold weather concrete project, it’s important to determine any special strength requirements or considerations. This will help as you schedule your pouring and determine which strategies you will use to keep your surroundings and materials warm. The predominant challenge you will face during a winter concrete project is ensuring that the concrete sets before it is exposed to freezing temperatures. You might take the following suggestions into consideration as you plan your upcoming project:

  • Use heaters to thaw frozen ground, snow or ice.
  • Use hot water to mix cement.
  • Keep dry materials in a dry, warm location.
  • Use products designed to set quickly. During cold weather, these products will not set as quickly as the instructions may indicate, but will set faster than conventional materials.
  • Use additives that accelerate set time. Use caution; if additives contain calcium chloride, any rebar or metal wire mesh in concrete will rust and cause concrete to crack.
  • Use extra cement (typically 100 lb/ cubic yard) to make the reaction hotter and cause concrete to hydrate more rapidly.
  • Remember that you still need to wait for bleed water to evaporate. Incorporating the water into the surface during finishing will weaken the surface. Bleeding starts later and takes longer during cold weather; you can use squeegees or a vacuum to remove water quickly.
  • Wait until concrete has reached desired strength to remove any framework. If the framework is removed too early, the concrete will be damaged and the surface could collapse.

Maintaining Ideal Temperature

After implementing the above suggestions, It’s important to consider how you will keep concrete at the correct temperature during the curing process. Concrete must maintain a temperature above 50 °F for approximately 48 hours for the correct chemical reactions to take place. Two popular options used during cold weather concrete curing are heated enclosures and insulated blankets. If using an enclosure, ensure that the structure is both wind and waterproof. Additionally, ensure that there is proper ventilation for the space heater. Heaters cause an increase in carbon dioxide that could cause carbonation in the surface of the concrete.

Powerblanket Concrete Blankets

Powerblanket® concrete blankets are an extremely effective option for attaining and maintaining the correct temperatures for concrete pouring and setting. Powerblanket® concrete blankets can be used to thaw ground before pouring concrete and again after finishing to keep concrete from freezing. Utilizing Powerblanket® concrete blankets will ensure that concrete is kept at the correct temperature for the necessary reactions to happen quickly and the desired strength to be reached.

How long does concrete take to set

How long does concrete take to set?

If you really want to know the truth, concrete never stops curing; it continually hardens forever.  However, for practical purposes, it reaches a point where further hardening will be so slow it becomes unnoticeable.  In this article, we cover the basics of what you need to know about “how long does concrete take to set.”

 

Concrete Never Stops Curinghow long does it take concrete to set

The continual hardening occurs because cement particles react with the water in the mix (hydration), and as long as cement is in contact with moisture, even miniscule bubbles, it will continue to form bonds.  This is minimal after “full strength” is achieved, but it is continual.  

 

Curing Time for Concrete

In standard industrial cases, full strength concrete is recognized at 28 days.  At seven days, you should have concrete that is cured to 70% full strength or greater.  But to answer the question of, “How long does concrete take to set?”, concrete setting time is generally 24 to 48 hours.  At this point the neighborhood dog will not leave his footprints in it, but you should keep it clear of heavy equipment during this time period. Most mixes are cured at 28 days.

 

Factors Affecting Concrete Setting Time

  • Moisture plays a critical role in curing time for concrete.  If there is not sufficient water in the mix, the concrete will cure too fast, resulting in weaker overall strength.  Too much moisture, often used in the finishing step will weaken the top layer and cause flaking.
  • Hot ambient temperatures and wind accelerate the evaporation of moisture–speeding concrete setting time.
  • The mix design has a lot to do with concrete setting time.  Some jobs will require accelerants because the area needs to be usable as soon as possible.  The accelerant will do its job and speed up the concrete setting time.  Accelerant mixes will show a weaker overall strength in the end, but will still meet strength requirements.

 

Powerblanket Concrete Blankets

If you are wondering about how long does concrete take to set, Powerblanket has a solution for your concrete setting needs.  If you are dealing with HOT conditions and your concrete setting too quickly, consider Powerblanket ICE.

Powerblanket ICE is portable cooling equipment that will keep newly poured concrete safe from heat, regulating concrete setting time in both regular and hot conditions.

The Powerblanket ICE Circulation Blanket is combined with either a cooler or chiller to achieve optimum results. The Circulation Blanket draws heat to the blanket in order to cool the concrete.

  • Use Powerblanket’s patented heat-spreading technology in reverse–the cooling blanket draws heat away and lowers the temperature of the concrete.
  • Take it with you on every jog.  It is easily portable.
  • Blanket cover and insulation are the same as the robust system used in Powerblanket heating products
  • Control the curing speed of newly poured concrete even in hot conditions

If conditions are cold, Powerblanket concrete curing blankets provide a manageable way to cure concrete effectively and confidently. Powerblanket curing blankets increase production by rapidly curing with consistent, even heat.

Concrete Curing Temperature Makes a Difference

How Warm Does it Have To Be To Pour Concrete?

Whether the conditions are hot or freezing, the ideal concrete curing temperature should be maintained at about 55°F to achieve the optimum concrete strength.

Curing the Hoover Dam

At its completion in 1935, the Hoover Dam was the largest dam in the world and a marvel of labor and engineering.  The first pour began on June 6, 1933. Rather than being a single block of concrete, they built the dam as a series of individual columns. The trapezoidal columns rose in five foot lifts. This method allowed the tremendous heat produced by the curing concrete to dissipate. If the dam were built in a single continuous pour, the concrete would have gotten so hot that it would have taken 125 years for the concrete to cool to ambient temperatures. The resulting stresses would have caused the dam to crack and crumble away (The Story).  

The heat and dryness of Nevada posed additional complex problems with the pour and concrete curing temperature.  When the concrete was first poured, river water circulated through cooling coils of 1″ thin-walled steel pipes. Once the concrete had received a first initial cooling, chilled water from a refrigeration plant on the lower cofferdam circulated through the coils to finish the cooling (The Story).

Concrete Curing is an Art

We live in a world where faster always seems better; however, concrete that cures too quickly or under hot concrete curing conditions can actually result in weak or unstable concrete.  If concrete is cured in cooler ambient  temperatures (32°F to 50°F) with moisture continually present, strength gain will be slow but the concrete will eventually reach a high strength. Concrete should not be allowed to get hotter than 90°F or to dry out during the curing period.

Best Concrete Curing Temperature

By “best” we mean “most thoroughly,” not the fastest.  High temperatures mean faster curing, but fast curing equates to weaker strength in the end.  The following study by Paul Klieger in the Portland Cement Association Research Bulletin 103 illustrates this concept.

concrete cure time chart with concrete curing temperature

Concrete Cure Time Chart with Temperature

At an age of 1 day the 120°F concrete was strongest and the 25°F concrete was weakest. By 7 days the high-temperature cured concretes had no more strength than the 73°F concrete or even less. By the age of 28 days the high-temperature concretes were weaker than the 73°F concrete. From 28 days to 1 year the 55°F concrete was considerably stronger than the 73°F concrete. All of this suggests that, provided there is continuous curing, concrete cured at about 55°F for the first 28 days ultimately reaches the highest strength (Concrete).

Hot Weather Concrete Temperature Limits

Hot weather concreting doesn’t simply involve temperature.  High ambient temperatures, winds, and relative humidity all play a role in “hot weather.”  Under hot heather conditions, the primary curing issue is having the top of the slab of concrete dry much faster than the bottom. As concrete dries it shrinks. This means that the top will be shrinking while the bottom is not. This creates internal problems with the concrete that will result in a damaged slab. The top and the bottom of the pour need to cure at the same rate (Placing).

Powerblanket® Goes to the Statue of Liberty

Reilly Construction out of Wrightstown, NJ won a bid from the U. S. Department of the Interior, National Parks to replace the roof of The Great Hall Statue of Liberty National Monument.  The Great Hall, which now houses the Ellis Island Immigration Museum, is considered one of the most symbolically important structures in American history. The Great Hall-Ellis Island was proclaimed a part of Statue of Liberty National Monument and is listed on the National Register of Historic Places.  Reilly nee
ded extra heat in the form of curing blankets to make this job happen.

 

The project involved removal of the existing inverted roof membrane assembly (IRMA) and replacement with a new multi-ply modified bitumen roofing system over a complicated tapered insulation deck assembly, approx. 60,000 Sq. Ft. The project also included the replacement of custom fabricated copper flashings and accessories throughout and the installation of a lighting protection system. Reilly worked with the NYS Historic Preservation Office (SHPO) to coordinate all the work.

 

Challenges Faced by Reilly

  •     Cold winter weather and high winds at this waterfront facility
  •     Working safely around thousands of tourists visiting this historic landmark daily
  •    Implementing various overhead protection plans at this historic landmark daily
  •    Mobilizing materials and equipment on a small island
  •    Limited laydown and staging areas
  •    Coordinating construction schedule with NPS & U.S. Park Police for VIP visits
  •    Ensuring compliance with the NYS Historic Preservation Office (SHPO)
  •    Day & night work


Finding Powerblanket

Dan DeSantis, the Senior Project Manager for Reilly, found Powerblanket products online and left his contact information. Upon follow up, we discovered that Reilly needed a heating solution to cure the masonry block work at the proper temperature (~50°F/~10°C) during December in New York and with the added chill of the water. Reilly used five Powerblanket MD0520 concrete curing blankets for the application, and appreciated the increased temperature control.

Concrete Cooling: Curing Concrete in the Summer Months


We talk a lot about the dilemmas posed to concrete curing during the cold winter months, and for good reason too. It’s difficult to get concrete to cure well when the temperature drops. But what about when the weather is hot? True, fewer problems exist for concrete curing during the summer, but excessively hot temperatures can cause concrete to cure too quickly. Don’t worry; we’ve got you covered here too, with our concrete cooling:

 

canstockphoto3975308Concreting in the Summer

We all know that summer is the ideal time for construction projects, and concrete pouring is no exception. But when the summer months get really hot, it can be a little too much of a good thing. In fact, concrete cures best in a range somewhere between 70° to 80° F. As you approach numbers as high as 90°, however, you’ll start to run into problems. Concrete experts suggest that if you anticipate experiencing temperatures higher than 77° F after pouring your concrete, you should have a plan for remedying the effects of the high temperatures. Since temperatures above 77° F are very common in the summer months, you’ll need to have a concrete cooling solution in place.

Why, you may ask? Because when concrete is poured in high temperatures, it can cure too fast. One of the major concerns with really short curing times is the reduction of strength due to the demand for high water content during high curing temperatures. Pouring concrete in hot weather also poses the risk of dehydrating the concrete, which will lead to shrinkage and cracking. With these risks in mind, it becomes imperative to have a plan in place for combating the hot weather, and we have just the solution for it too.

 

Powerblanket® ICE for Concrete Cooling

Our new Powerblanket ICE cooling blankets allow you to simplify the concrete work you do in the summer by eliminating the side-effects associated with hot weather concreting. Just look at these features:

  • Powerblanket ICE uses Powerblanket’s patented heat spreading technology in reverse to draw heat away from the concrete while simultaneously circulating coolant throughout the blanket surface.

Concrete Blankets From Powerblanket®

Cement Curing Blankets

Cement curing has always been a challenge in cold weather. Historically, experts have employed many different methods in order to aid in and speed up the curing process. Some methods are better than others. The best, in our opinion, is using concrete curing blankets from Powerblanket. Here’s why:

Concrete Curing Blankets

 

Why Electric Curing Blankets?

When placing concrete in cold weather, protecting the asset (the concrete) is not optional. For years now, experts have used insulated blankets to both protect the concrete and speed the curing process at the same time. Concrete cures due to a chemical reaction that generates heat as a byproduct. So insulating the concrete allows that heat to be trapped and used to aid in the curing process. Concrete cures fastest in very warm conditions, so this makes the use of an insulated blanket a practical and theoretically sound practice.

Of course, the use of traditional concrete curing blankets isn’t the only method employed among professionals. Other common curing interventions include:

  • Chemical additives
  • Hydronic heating systems
  • Electrically-powered concrete curing blankets
  • Poly/tarp cover with forced air heat applied

Sometimes the circumstance will allow for the luxury of a postponed pour, in order to take advantage of an expected temperature change.  But more often than not, schedules and deadlines make it imperative to institute curing assistance to get through less-than-favorable weather.

This is where Powerblanket Concrete Curing Blankets come in. As much as traditional curing blankets aid in protecting and accelerating the curing process, Powerblanket curing blankets provide both insulation and heat, protecting and accelerating all the more. Our patented blend of technology delivers an even distribution of electrical heat to the surface area of the blanket, trapping the heat of the chemical reaction in the concrete and adding the additional heat needed to accelerate the process even further.

Since Powerblanket Cement Curing Blankets insulate and heat, they effectively accommodate the hydration of the concrete as well. How well do they really work? Take a look at our case study to see an example of curing nearly three times as fast with our blankets.

The technology behind Powerblanket curing blankets serves to achieve several primary objectives, including:

  1. Preventing damage as a result of freezing in the early stage of curing
  2. Producing sufficient, specified strengths in a timely manner
  3. Insuring durability and long-term structural integrity
  4. Keeping projects on schedule, regardless of weather

So before you’re faced with a project that must go on despite inclement temperatures, make sure you have a plan on how to protect your concrete and keep your deadlines met. When considering the options you have before you, we’re confident you’ll find our solution to be the best answer out there.
