Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need. To make concrete there are four basic materials you need: Portland cement - You can buy this in a …

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

hydration of cement and water form a stone-like mass called paste. When the paste is intermixed with aggregates, (sand, gravel, crushed stone or other granular material), it acts as an adhesive and binds the aggregates together to form concrete. The hydration begins immediately upon the water and cement coming in contact with each other and

Crushed sand particle though shaped, does not have the spherical shape of natural sand. Hence the crushed sand will have greater water demand than that of natural sand resulting in slightly higher cement consumption. However, if crushed sand is properly …

A cement sand ratios of 1:2, 1:2.5 and 1:3 were tested with cement water ratios ranging from 1:3 to 1:65. Because Rao uses a different cement type, and a much lower sand ratio, these tests are relevant in terms of basic trends, and not absolute strengths [Rao, 2001]. As expected, the mix containing the lowest cement to sand ratio, held consistently

Calculation of the amount of cement, sand and gravel for making concrete. data-full-width-responsive="false">. Calculation of Concrete. The number and cost of materials for making 5 cubic meters of concrete. Bags of cement on 50 kilogram. The required number of bags of cement 30 ( 1500 kg) The cost of cement 6000. sand 3750 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.
