• #### Use of sea sand as fine aggregate in concrete making

Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water. The approximate ratios of these components are as below: Based on the ratios and the anticipated cement consumption in the country, the expected requirement of sand will Calculate Cement Sand & Aggregate M20, M15, M10, M5,If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give high-density concrete. Hence use 1:2:3 for good strength and 1:2.5:3.5 for moderate strength. If you want to increase strength then reduce the water content and use Chemical admixtures like super plasticisers.
