Concrete Curing: Not Just a Wintertime Problem

If you’re in the business of concrete, then you know that winter poses the most complications when it comes to proper concrete curing. However, you’ll be equally aware of the fact that summertime also has its challenges.

Summertime Concreting

Sure, winter is a far more difficult time to deal with when pouring concrete. Proper curing involves ideal temperatures, and winter imposes on these ranges more than any other season. That’s why when it comes to pouring concrete in winter, you need the assistance of a good concrete curing blanket. But what can be done to counter the challenges of summer, and what are those primary challenges?

In the summer months, you don’t have to worry about freezing temperatures. Instead, you need to watch for levels of relative humidity, temperature fluctuations between night and day hours, and an increase in the water demand for concrete curing. With these factors to consider, careful monitoring of the concrete is still an important element of the job. Hotter temperature and low humidity can increase the need for additional water, and large fluctuations between the daytime and evening temperature can pose significant problems too.

If there is the risk of a rapid drop in temperature, then there is the risk that your concrete could crack. Even though the temperature may be ideal for curing during the day, that doesn’t mean it will be at night. Certain regions can experience significant temperature variances between daytime and evening hours, and these variances should be considered potentially problematic while your concrete cures.

 

Using a Concrete Curing Blanket in the Summer?

It may seem a bit of a stretch to suggest the use of a curing blanket during the summer months, but the reality of the situation is that it can be a very reasonable call. Think about the potential scenario of dropping temperatures at night. If your concrete is curing well during the heat of the day, and then experiences a drastic drop in temperature at night, then it’s going to affect the cure and even cause potential cracking.

Using a concrete curing blanket at night would allow you to regulate the temperature range even if it’s dropping. This would produce a more uniform cure and would also speed up the process significantly. The blanket likely wouldn’t be needed during the day, but applying it at night could greatly decrease the fail rate of an expensive and time consuming project.

Powerblanket at the World of Concrete—A Demo in Concrete Curing

Earlier this month, Powerblanket attended the 2015 edition of the World of Concrete at the Las Vegas Convention Center. This year’s exhibition attracted 55,779 registered professionals. In addition, the event drew in 1,459 companies exhibiting their products and services. For Powerblanket and its concrete curing demo, the event proved to be a great way to engage with those in need of the company’s products.

 

 

Powerblanket and the World of Concrete

For Powerblanket, this year’s World of Concrete was an exciting investment of company time and resources. Powerblanket ran a concrete curing demo to demonstrate the effectiveness of Powerblanket® curing blankets on the set times and structural integrity of concrete pours. Those who were present were able to witness for themselves how much efficiency the curing blankets added to the curing process. Not only were the blankets able to cure the concrete nearly three times as fast, but they were also able to increase the strength of the concrete by 50%.

The slab used for the demonstration was 8” thick with a mix design that was formulated to provide a minimal PSI of 4,000 in only two days.  The slab was poured two days prior to the demonstration, and for the purposes of the demonstration, one portion remained unheated while the other section was covered in an MD series Powerblanket® curing blanket. At the beginning of the demonstration, the unheated portion of the concrete measured close to the 4,000 PSI that was required for the minimal target. Then the Powerblanket was added, and the portion of the slab that was heated by the Powerblanket MD Series concrete curing blanket measured a consistent 6,000 PSI after only 16 hours in place. That’s a PSI strength increase of 50% over the unheated portion of the concrete slab.

Powerblanket® curing blankets allow for such efficiency through the company’s patented technological approach to concrete curing and many other heating solutions. Not only do Powerblanket® curing blankets insulate the chemical reactions responsible for concrete heat exchange, but they also add heat to the equation—making them far more efficient than the common curing blanket.  Through the Powerblanket design, electrical heat is evenly distributed through the entire application, allowing for quicker set times and stronger concrete.

“Seeing people’s reactions to the demonstration was exciting,” said Ryan Jensen, Marketing Director for Powerblanket. “It was clear that everyone was impressed with the outcome.”

As a result, Powerblanket has engaged with more customers in an industry they already heavily serve.

A Concrete Curing Solution

If you live in the North American Mountain West, or any region where it gets cold during the winter months, chances are you’ve seen chipping concrete. Have you ever stopped to think what causes concrete to chip? Improper curing is what causes it, but with a good concrete curing blanket, this problem can be completely avoided.

Not All Concrete Curing Blankets Are The Same

If you’ve ever seen chipped concrete before, it’s likely due to cold weather. But we’re not talking about cold weather after the pour. No, chipping concrete often results from it being poured when it was too cold. This means the concrete never fully cured. Thus, it became brittle and flaky. The simple solution to this dilemma is either to wait until its warm enough outside, or else apply a concrete curing blanket.

If you did a Google search for concrete curing blankets, you’re likely to find a myriad of options. But not all these options are the same. A good majority of the curing blankets out there are merely insulation blankets. Now insulation is a good thing to have in a curing solution, but it’s only half of the equation. The problem with simply insulating the concrete is twofold.

If you have a concrete blanket that only acts as an insulator then it’s not likely to help in the extreme weather. This is the first problem with an insulation blanket. The second is this: with only insulation on your side, you’re not going to be speeding up the curing process at all. When concrete cures, a chemical reaction occurs. This reaction causes the concrete to put off heat. With this in mind, placing an insulated blanket over the concrete will help to keep some of this heat in, but the amount of heat it will trap isn’t substantial enough to help cure concrete in really cold weather, or to speed up the curing process much either.

The Real Solution is Electric

This is why you need an electric curing blanket, or a heated curing blanket, to get the job done right. Electric curing blankets will both insulate and heat the concrete to an ideal temperature for curing. With the characteristics of a heated blanket at play, you can properly cure concrete in very cold temperatures. What’s more, even if the weather isn’t that bad, you can apply such a solution to speed up the curing process by leaps and bounds.

When it comes to picking the best electric curing blanket, there are a few major aspects to be concerned with.

  • Number one, you want to make sure you get a blanket that will evenly distribute the heat throughout the entire application area. If the blanket is hotter in some places than others, you’re not going to get an even cure.
  • Number two, you want to make sure you get a product that is properly certified for safety and efficiency. And number three, you want to make certain you purchase a blanket that can regulate its own heat. A blanket with a thermostatic controller will enable you to apply the heat and walk away without worrying whether it will keep consistent heat for the whole time you’re curing.

The Wonders of Concrete: From Creativity to Concrete Curing

When most people think about concrete, their minds quickly turn to the common, grey, lifeless slabs that we walk and drive on. You can’t fault anyone for envisioning concrete in this way, but is it really a fair representation of such a versatile and varied construction material? We don’t think so. From creativity to curing, concrete is a truly amazing product.

Concrete’s Real Potential

If you’re one of the individuals whose thoughts turn to sidewalks, interstates, overpasses, and patios when you hear the word concrete, well, it’s really to be expected. These forms of concrete application are certainly the most common. But there are also many other common uses that the typical person may not been clued in to.

Instead of settling on the usual image of concrete, take a chance to expand your horizon. Have you ever stopped to think about the many different types of pavement that exist? The fact of the matter is that much of the pavement you’ve seen, both indoor and outdoor, is some form of concrete. You see, concrete has possibilities for design that many people never even stop to consider.

Decorative Concrete

For those in the know, concrete that falls outside of the stereotypical application and image is known as decorative concrete. And what some people have been able to do with decorative concrete is simply amazing.

Take for example the patterns that skilled concrete layers have been able to weave into what would otherwise be a very boring driveway. Perhaps you’ve seen the same techniques employed in outdoor walkways in and around historic downtown districts, malls, or river walks. Think of the innumerable possibilities that exist with such a method. Think of this, and you’ve only scratched the surface, though.

Even with as many outdoor uses concrete has, there are just as many indoor application methods. In fact, these types are the most stunning. Take a look at the picture below the driveway. Looks like tile; doesn’t it? Nope, it’s concrete, decorative concrete that has been designed to look like a very impressive tile pattern. Now take a look at the image below that. Looks like laminate wood flooring; doesn’t it? Actually, it’s concrete too.

This sort of thing is quite the surprise; isn’t it? For those who first venture into the realm of decorative concrete, the possibilities at first seem almost unbelievable. Oh, but they’re a very real and valuable way to make expanded use of one of the world’s most common construction products. To find more great examples of concrete usage, just type into Google: “decorative concrete” (under an images search).
