The compressive strength was calculated by using the equation  : f= p/a, where f is compressive strength of specimen in mega pascal, p is the maximum applied load by newton and a is the cross-sectional area estimated in mm 2.
How to Calculate Compressive Strength of Concrete?
Calculating the compressive strength of concrete is a vital part of any construction project. The compressive strength of a concrete mixture is a measure of its resistance to crushing and deformation under stress.
It is important to know the compressive strength of concrete before using it for any construction project. Doing so can help you determine the appropriate mix design for the job and also ensure the safety of the structure.
In this article, we will discuss how to calculate the compressive strength of concrete. The first step in determining the compressive strength of concrete is to determine the type of concrete and its proportions.
Different types of concrete have different compressive strengths, so it is important to know which type you are using. The most common types of concrete are high–strength, medium–strength, and low–strength concrete.
Once you have determined the type of concrete, you should also determine the proportions of the concrete. This includes the ratio of cement, sand, and aggregate in the mix.
The next step is to measure the concrete cylinder. This is done by using a Cylinder Molds which is a device that is used to form a concrete cylinder for testing.
It is important to ensure that the cylinder is of the correct size and shape before testing
