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

Title : Concrete Cube Compressive Strength (7 days) Introduction : To determine the strength‚ maximum load can be applied and workability of concrete mixture. Theory : Hard concrete test were conducted at the age of 3‚ 7‚ 14‚ 21 and 28 days after curing(but we tested it for 7 days only). The concrete strength increases according to the age‚the mixture of its concrete design and the strength increment will continue for sometimes. Nevertheless‚ for most of the work‚ the concrete strength on
