Concrete mix ratio is a relative proportioning of cement, sand, aggregate and other materials needed to prepare different grades of concrete. For example, the prescribed Nominal concrete mix ratio of M20 concrete is 1:1.5:3, hence for every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate, in volume, is needed to prepare M20 grade ...

The heat transfer in concrete material at normal operating temperatures is mainly by conduction. The properties of concrete are influenced by the spatial spreading and volume ratio of its elements, such as aggregate, water cement and voids. The voids inside concrete have an important effect on the mechanical and thermal properties of concrete [59].

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.

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.
