Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : : 3) Total Part of the Concrete = 1++3 = Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

RC Beam Column Building. Concrete structure can be made with many different ways. Some are given below: Plain Cement Concrete. Plain cement concrete is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportion. The concrete structure made by using the plain cement concrete has good compressive strength but very little tensile strength, thus limiting its

The minimum amount of steel reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behavior is avoided as well as any localized failure, if the member is not overreinforced. In other words, there is a reinforcement percentage range, depending on the sizescale,

Concrete has relatively high compressive strength (it doesn''t crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
