Ensure the cubes are fully submersed at all times and record the tank water temperature at least daily. Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however ...

Hence, to prepare 1 cubic meter of M20, M15 and M10 concrete, 1.57 cubic meters of "total dry volume" of cement, sand and aggregate are needed, whereas to prepare 1 cubic meter of M7.5 and M5 concrete, 1.52 cubic meters of "total dry volume" of cement, sand and aggregate are needed. Many websites are giving different values for the "total dry volume" of the ingredients.

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.

The water for curing should be tested every 7 days and the temperature of the water must be at 27+-2oC. Procedure for Concrete Cube Test.
