How to Calculate Quantities of Cement, Sand and Aggregate ...
Feb 07, 2017 So, 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.

Sand Extraction: 1. Introduction - GreenFacts
Introduction. 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.
