So, Sand required = *1600 = 115 kgs. and Aggregate required = *1450 = 209 kgs. Considering water/cement (W/C) ratio of We can also arrive at the Water required = 50* = kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and kgs of water to produce M20 grade concrete.
· Cement – which is the "glue" that binds concrete together – is a fine powder made up of crushed minerals such as limestone and clay that function as a binder. Cement can be made from a variety of materials, but it can't be used on its own. In fact, Roman cement was crushed rock with burnt lime, volcanic ash, and brick supplements.
