Concrete is a composite product obtained artificially by hardening of mixture of cement‚ sand‚ gravel and water in pre-determined proportions. When these ingredients are mixed‚ they form a plastic mass which can be moulded in desired shape. It gets hardened into hard solid mass. Water is one of the important ingredients of concrete. This is required not only for chemical reaction‚ but also for curing purposes. The chemical reaction of cement and water‚ in the mix‚ is relatively slow and requires

Ingredients for concrete are cement‚ fine aggregate‚ coarse aggregate and water. The best concrete can be obtained by mixing the ingredients in correct proportions. The ideal proportion of concrete will be that‚ which produces greatest strength and solidity at the least cost. In estimating the quantities of ingredients for cement concrete it should keep in mind that voids of coarse aggregates are filled up by sand and voids of fine aggregates are filled up by cement. The concrete mix of 1: 1: 2 and
