Concrete material properties have to do with three factors: load-bearing, tensile strength, and compressive strength. These are the three main aspects that have to do with the ability of concrete to bear the weight. We will now look into the first one:
Concrete Material Properties
Load-bearing refers to the strength of concrete material when it is used in structures, especially buildings. There are basically two types of loads that are to be considered here: dynamic and tension.
The dynamic load is what can be expected to be developed on a building once it has been built, while the tensional load is what can be expected to develop on the concrete once it has been poured on the ground. Basically, dynamic means the increase in weight over time, while tension means the decrease.
The second factor that has to do with concrete material properties is the ability of the concrete to bear the loads. This is done through the use of aggregate and residual adhesives concrete contractor nashville tn. As you probably know already, the typical texture or surface texture of concrete material is called an aggregate.
Through the application of these additives to concrete materials, we achieve a better ability for the structural members to bear the load that is being placed upon them. Aggregates are primarily water-based and chemical additives that allow concrete materials to be more flexible, as well as more resistant to abrasion, cracking, wear and tear, and shrinking.
As you may also know, another one of the concrete material properties is its characteristic compressive strength fck. This refers to the level of compressive strength that a concrete member is able to withstand without cracking. This is actually one of the three specific limits of strength in materials – the others are the thermal contraction and tensile strength.
Now, let us move on to the other three concrete property which is encapsulation. Through the application of various corrosion-resistant substances such as polystyrene and polyurethane coatings, concrete surfaces are made more resistant to corrosion. There are several grades of these materials which are differentiated based on the number of additives used in the formation of the surface.
The more additives, the higher the grade of the concrete product. For example, there is a concrete grade A which has one percent polystyrene while there is a B which contains five percent polystyrene, and a C which contains one percent of both polystyrene and polyurethane. This kind of classification is usually expressed graphically, such as in Figure 1 below.
Let’s now move on to the concrete’s characteristic tensile strength. This refers to the maximum load that a single concrete member can be lifted by a typical mechanism. The figure below shows the relationship between concrete fctm R-values and tensile strength, or L values. The lower the fctm R-value, the better the tensile strength of the concrete member. The higher the value, the stronger the concrete material.
