Cold Chain Logistics

Cold Chain Logistics

Effective cold chain logistics are essential to keep fruit fresh, flowers from wilting, and various chemicals and pharmaceuticals  safe during transit. In all modes of cold chain transport, temperature sensitive products are susceptible to a loss of quality.

The Global Cold Chain

Globally, there is a heightened interest in healthy food. Consumers are looking for higher-end products, such as Alaskan salmon, that must travel long distances and move quickly to ensure freshness and quality.

“Demand for fresh food is growing, and that requires increased innovation to overcome capacity and infrastructure constraints, and mitigate disruption risks to ensure quality delivery,” adds Tim Smith, executive vice president, sales and business development, for Lineage Logistics. Adjusting to these new demands while maintaining prices, places added pressure on every element of the supply chain.

Maintaining control of products is a major concern for many shippers.

Cold Chain Must Maintain Quality

In the food industry, there is an increased focus on quality, health, and integrity. Cold chain logistics must ensure that changes in texture and taste do not occur.  When a shipment strays outside recommended temperatures, quality will deteriorate rapidly.   

More premium products with a shorter shelf life and greater sensitivity to temperature, are raising the bar for temperature control and cold chain logistics.  Refrigerated warehouses across the food cold chain must maintain as many as five different temperature zones.

Cold Chain Logistics with Powerblanket

Powerblanket offers innovative cold chain solutions that will meet the demands of unique temperatures during transit. With the new Powerblanket ICE industrial cold chain solutions, you can efficiently regulate temperature-sensitive material under both regular and hot conditions. Transporting food, chemicals, and other heat sensitive materials is no longer a major challenge.

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.

  •  Cure concrete 2.8 times faster than conventional, insulated blankets
  •  Maintain moisture throughout hydrating process
  •  Easily installed and removed
  •  Produce cold weather concreting strength of up to 3,925 psi in 72 hours
  •  Prevent a freeze cycle
  •  Thaw ground and frost from job site before you pour
  •  Reduce downtime & increase profitability

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).

Total Process CoolingTotal Process Cooling

At the end of the day, it is important to know that the cooling solution in place will do it’s job.  Powerblanket’s world-class engineers create total process cooling systems that are reliable, efficient, and effective.

The Basics

When it comes to industrial process cooling, materials make all the difference.  Powerblanket ICE blankets are made with a rugged white vinyl that provides robust insulation.  The white reflects the sun’s rays and other heat to keep the contents cool.  Along with the rugged outer shell, these blankets use Powerblanket’s patented heat spreading technology in reverse to pull the heat from the contents and the container and then transfer it into the blanket. Powerblanket ICE total process cooling solutions are portable, requiring only 120VAC for operation.

Industries

Keeping critical materials at safe temperatures has never been so easy.  Powerblanket ICE industrial process cooling works especially well for transportation, manufacturing, spray foam, motor, fermentation, welding, and biomedical industries with products ready to ship for tank, drum, and tote cooling.

Hot Weather Concreting Made Easier

Hot Weather ConcretingHot weather concreting

Hot weather concreting problems are most often encountered in the summer; however, any condition that increases curing rates and strips the concrete of moisture is considered hot weather concreting.

Pouring Concrete in Hot Weather

With temperatures rising and summer approaching, attentions shift from protecting concrete from the cold to concreting in hot conditions.  When pouring concrete in hot weather, special procedures should be followed for proper mixing, placing, finishing, and curing.  High ambient temperatures, high concrete temperatures, low relative humidity, and/or high winds impair the quality of freshly mixed and recently placed concrete (Hot).  Pouring concrete in hot weather affects laboratory test results, showing that higher temperatures affect the compressive strength gain of hardened concrete. Even though concrete poured in hot weather will produce higher early strength but as time goes by, the ultimate strength will be lower than expected (Rodriguez).

Water Loss

Hot weather concreting causes increased setting rates and rapid water loss.  Shrinkage and cracking are usually associated with hot windy weather.   The major side effect of faster curing and water loss is decreased overall concrete strength.  It is critical to prevent moisture from evaporating from the concrete surface. The evaporation rate removes surface water necessary for hydration , and thermal cracking may result from rapid changes in temperature, ie. pouring concrete on a hot day followed by a cool night (CIP 12). Proper mix design can compensate for these conditions, and in combination with protective measures to prevent rapid evaporation, quality concrete can be poured in hot temperatures (Rodriquez).

Adding water can increase concrete workability. However, adding water beyond the amount required by the approved mix design increases the water to cement ratio. This, in turn, can result in decreased compressive strength and an increased chance of cracking (Hot).

Recommendations for Hot Weather Concreting

Preparation is key and there are several basic precautions that can reduce the damaging effects of hot weather on concrete:

  • Use mix designs that are less susceptible to the effects of hot weather. The use of low-heat-of-hydration cement and certain admixtures (such as hydration retarding and/or water-reducing admixtures) are two standard approaches.
  • Keep concrete as cool as reasonably possible. ACI 305R does not state a maximum “as-placed” or “as-delivered” concrete temperature, but 90° F is commonly used. Substituting chilled water or shaved ice for a portion of the required mix water can help.
  • Limit the amount of time between loading the concrete at the plant and placement/finishing at the site.
  • Limit water addition at the job site, except to adjust slump upon arrival (when permitted by mix design).
  • Avoid or limit hydration accelerating admixture use.
  • Schedule large concrete pours in the early morning or evening when temperatures are cooler and have the manpower available to complete the job as quickly as possible.
  • Use temporary wind screens and water misting nozzles to reduce surface moisture loss (Hot).
  • Consider using a concrete cooling blanket to both retain moisture and protect the concrete’s surface from high ambient temperatures.

Protecting Materials from heat

Protecting Critical Materials from Heat with Powerblanket ICE

Protecting Critical Materials from Heat

Under certain conditions and with certain materials, heat is the enemy: ruining epoxies, and interfering with the brewing process.  You can, however, protect critical materials from heat when the effects of heat are understood and proper precautions are in place.

Epoxy

Epoxy are many types of resins with similar properties and chemical structures. Typically used for adhesives, protective coatings and molds, epoxies are hard and notably inert after curing. Before curing epoxy is more fluid. The chemical reaction that results in epoxy is exothermic, meaning the reaction when epoxy is mixed creates heat. Adding more heat to this reaction makes the reaction advance faster. More heat, whether ambient temperatures or heat accelerators, will speed the chemical reaction.

In general, temperatures below 50°F/10°C are too cold for epoxy to cure properly. Temperatures around 70°F/21°C are ideal. If epoxy is kept in a container or spread in a thick layer, the heat from the reaction dissipates slower, and the heat of the chemical reaction can speed its own curing process (Legget).

Heat speeds everything about the curing process of epoxy.  If there is a need to store the epoxy, some plans for cooling must be in place.

Fermentation

protecting materials from heatHeat is an important part of the fermentation process; however, if heat enters the process at the wrong time, or lasts for too long, it can result in undesired flavors and aromas that compromise the quality of the spirit.  Spirits spend years locked inside barrels during the aging process, undergoing a series of seasonal climatic changes that trigger chemical changes. Controlling the temperature of actively fermenting wort (the sweet infusion of ground malt
or other grain before fermentation, used to produce beer and distilled malt liquors)
can have a major impact on the flavor of the finished beer. Fermenting above the normal temperature range may produce excessive fruity-flavored esters or harsh-flavored fusel alcohols (Stika).

Normal ale fermentation temperatures range from 68-72 °F/20-22 °C and lager fermentation temperatures from 45-55 °F/7-13 °C. The heat generated by an active fermentation can warm a typical 5-gallon batch of beer by 10 to 15°F/5.5 to 8.3°C (Stika).
