The Different Types of Concrete

Concrete Jackson Michigan is one of the most used materials in construction and in the same way it is also one of the most important materials used for construction. Without concrete, we would not be able to drive on the roads that make it easier for us to get to our desired destination every day. We would not even be able to walk on the sidewalks if concrete never existed. Although, there are different types of concrete that make up the everyday things we use or walk on. Here are some of the different types of concrete and what they are made up.

Concrete

 

The first type of concrete is called normal concrete. This material is made up of aggregate, water, and cement. This type of concrete has a setting time of 30-90 mins depending on the altitude and temperature of the concrete. It will start to harden gradually, and it would reach its peak strength at around 90 days where it would be at peak strength. This type of concrete is strong in compression but weak in tension. This concrete would not be good in conditions of low temperatures because it would not fare well against freezing and thawing.

The second type of concrete is called high strength concrete. It is said to have a strength of 6,000 pounds per square inch. The material is made by lowering the water to cement ratio to 0.35 or lower.  The secret of this high strength concrete is the addition of silica fume. Silica fume does not allow the formation of free hydroxide crystals in the cement which would lessen the strength of the concrete because it would affect the cement aggregate bond. Although one downside of using high strength concrete is the material not being as workable as other types of concrete. To make it more workable, people would usually add plasticizers to make it more workable without sacrificing the strength of the concrete.

The next type of concrete is called high-performance concrete. This type of concrete is the better version of the high strength concrete. It is better because it is strong, durable, and its workability is way better than that of the high strength concrete. It is also very tough and can not last long even in the severest of environments. This concrete is made by lowering the water to cement ratio to 0.25. The high workability of this concrete is attained through the addition of the super plasticizers, but this concrete is not as good against freezing and thawing like the normal concrete.

Another type of concrete is called the air entrained concrete. This is one of the most technologically advanced cement because this type of cement would be able to withstand freezing and thawing. This is attained by adding air entraining admixture to the cement. It lowers the surface area of the water and in turn, allows it to form bubbles and these bubbles are the ones that trap the air in the cement. These are some of the many types of concrete that are available today.
