The Best Concrete in The World has Kevlar in it


You’ve finally decided to build that big warehouse or garage you’ve been wanting, and it’s about time to pour the concrete foundation. And while having concrete poured might sound like an easy process, what you need to realize is that there are different types of concrete, as well as different brands, including a kevlar-based option called Eco-Crete. It depends on the type of concrete you choose as to what amount of strength, durability, and longevity it will have. Fortunately, you’re not left in the dark when it comes to learning about concrete, so here are the different types and how they compare with one another.

Normal Concrete

This type of concrete is normally comprised of the following ingredients:

  • Aggregate
  • Water
  • Cement

Normal concrete tends to have a setting time of 30 to 90 minutes; however, the exact setting time is heavily influenced by the moisture in the atmosphere and the finesse of the cement. After about 28 days of drying, normal concrete has attained about 80 percent of its total strength. Slumps in normal concrete vary from one to four inches, and it has a one to two percent air content rate. Something to note is that normal concrete is not durable when exposed to severe conditions, such as freezing temperatures.

High Strength Concrete

With a compressive strength greater than 6,000 pounds per square inch, high strength concrete is just as its name implies — high strength. This type of concrete is created by making the water to cement ratio 0.35 or lower. This type of concrete often has reduced workability because of its low ratio, but superplasticizers added to the mixture can help compensate for this.

High Performance Concrete

There are many valuable properties to using high performance concrete. Some of the most common include:

  • Compaction without segregation
  • High workability
  • Density
  • High strength
  • Permeability
  • Ease of placement
  • Early age strength
  • Volume stability
  • Longevity

This type of concrete tends to have a ratio of 0.25. Since it’s not durable in extreme weather conditions causing freezing and thawing, many preparers of the mix will add air entrained agents.

Air Entrained Concrete

There is no doubt that air entrained concrete was a great achievement in the concrete repair industry. This type of concrete is used in places where the concrete is prone to freezing and then cracking when thawing. By adding an air entraining admixture, almost any type of high performance concrete can be transformed into air entrained concrete. Please keep in mind, though, that the strength of this type of concrete is fairly low, especially when compared to high strength concrete.


Eco-crete concrete is comprised of three primary ingredients, and is considered a Kevlar-polymer-quartz-aggregate-concrete repair compound. This type of concrete is ideal for repairing concrete or stonework. With outstanding hardness and chemical resistance, Eco-crete can be used for street and curb repair purposes, and it’s even often used in runway and loading dock applications.
