### What Is the Formula for Concrete Mix? -

· The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it's inadvisable to exceed a water to cement ratio of, which translates to 55 pounds of water for every 100 pounds of cement. When mixing concrete, it's necessary to ensure that there is an adequate amount of aggregate. Leaving out the stone

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

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.
