The process for estimating Cement, Sand and Aggregate Quantity in Concrete
This construction video provides detailed methods for estimating the quantity of cement, sand and aggregate in cement concrete to figure out the cost of all the materials. In this video, the volume of PCC to be prepared is taken as 10 cubic meter that is to be completed with M15 grade of concrete in the ratio of 1:2:4.
In a simple term, concrete is defined as a blend of paste and aggregates. The paste is formed with portland cement and water and covers the surface of the fine and coarse aggregates. With a chemical reaction known as hydration, the paste is solidified and becomes stronger to develop the rock-like mass called concrete.
Due to its longevity, firmness and comparatively marginal cost, concrete is mostly recognized for the buildings & infrastructures like houses, schools and hospitals as well as airports, bridges, highways and rail systems all through the globe.
Cement is actually a vital component of concrete. This fine powder is amalgamated with water, sand, and gravel or crushed stone (fine and coarse aggregate) and develops the rock-like mass known as concrete.
