Jul 26, 2020 Ans. :-11 bags (0.385 m3, 554 kgs) cement are required for 1 cubic metre of M25 concrete. How much sand required for M25 concrete. We have given dry volume of concrete is equal to 1.54 cubic metre and part of sand in concrete mix is equal to 1/4, density of sand

MoreSo, Sand required = 0.072*1600 = 115 kgs. and Aggregate required = 0.144*1450 = 209 kgs. Considering water/cement (W/C) ratio of 0.55. We can also arrive at the Water required = 50*0.55 = 27.5 kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 27.5 kgs of water to produce M20 grade concrete.

MoreAug 05, 2014 Sand has by now become the most widely consumed natural resource on the planet after fresh water.

MoreSep 08, 2015 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.

MoreIntroduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
