The 20th century saw various developments and modifications in the properties, characteristics, and types of concrete. The researchers from various countries like UK, USA, etc., carried basic research practices to know better about concrete and many other related building materials.
This knowledge aided them to develop the techniques related to construction, rules and specifications of the resources, the proportions of the ingredients used in the concrete and so much more.
They got to know that the properties of the concrete are not influenced by a single factor but many. It depends upon the proportions of the sand, cement, water and the aggregates. The ratio in which the mixture is prepared creates several types of concrete. These properties are mentioned below.
- Grades Of Concrete
The grades of the concrete define two things.
On the other hand, the measurement of the grade of the concrete is calculated in terms of the MPa. Here,
- M= concrete Mix
- Pa=overall compressive strength
The compressive strength can be defined as the strength of the construction to withstand the weight without any defect or crack.
The value of the comprehensive strength of the normal construction varies between 15MPa to 30MPa. The grade can go higher in the case of industrial and commercial structures like factories, bridges, skyscrapers, etc.
2. Concrete's Modulus Of Elasticity
There are multiple factors that influence the modulus of elasticity of the concrete. The major ones are the ratio of the materials mixed, type of the cement and the aggregates used.
Generally, the modulus of elasticity is equal to the compressive strength. To express this measurement, a formula is devised by the IS: 456-2000 code. It says-Ec=5000√fck. Here, EC stands for the static modulus of concrete's elasticity which is represented in N/mm2. Also, fck is the compressive strength that is measured in the N/mm2.
3. The Tensile Strength Of The Concrete
The occurrence of the defect in the concrete structure depends upon the tensile strength of the concrete. Normally, concrete comes with low tension. As compared to the compressive strength, the tensile strength is 1/10 times lower.
The factor that controls the damage to the concrete with the passing time is its high durability. It prevents the concrete to decay for a longer period of time.
The factor that affects durability is the penetration of water or other harmful substances. In order to save the concrete and increase its life, there are a few things that must be taken care of. For instance, take an adequate amount of cement while preparing the concrete, maintain well the ratio of the water and cement in the mixture.
These are some of the important factors that help in maintaining the quality of the concrete. If you need high-quality concrete, you can search the internet and navigate the websites of the best concrete suppliers in the town near you like RMS Concrete. These professionals know about the kind of concrete that the different types of construction requirements.
