Proportioning of Concrete Ingredients
The main ingredients of concrete are cement, fine aggregates, coarse aggregate, and water. The mix of each quantity in correct proportions will give a quality and best concrete mix. "An ideal concrete is that concrete mix with greater strength and solidity at the least cost".
Quantity estimation of the concrete mix has to be carried out by keeping in mind that the voids that are formed by coarse aggregates are filled by the fine aggregates. And the voids of fine aggregates are filled with cement.
