consumption of sand for concrete:

Sand: most widely consumed natural resource after fresh water.
Aug 05, 2014 Sand has by now become the most widely consumed natural resource on the planet after fresh water. [1] The annual world consumption of sand is estimated to be 15 billion tons, with a respective trade volume of 70 billion dollars. Over the last two centuries sand has become a vital commodity for our modern economies:

How to Calculate Quantities of Cement, Sand and Aggregate ...
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.

Sep 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 highdensity 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.

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.
