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. weight of coarse aggregate = 3 x 364.5 = 1093.5 kg. concrete calculator: calculate quantities of materials for.
The right amounts of ballast or sand-aggregate can also be expressed in simple ratios. so for the concrete mix mentioned above, your cement: sand: aggregate ratio should be 1:2:4 or ballast to cement ratio of 6 to 1. for a low-grade concrete with 10mpa strength, the perfect ratio should be 1:3:6. for 30mpa concrete use.
The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate. i would suggest the ratio of 1:2:3 or 1:1.5:3 for m20 grade concrete and 1:2:4 or 1:2.5:3.5 for m15 grade concrete. if you prepare concrete with your ration then the concrete will have too much.
The “m” refers mix and number after m (m10, m20) indicates the compressive strength of concrete after 28 days of curing and testing.. m indicates the proportion of materials like cement: sand: aggregate (1:2:4) or cement: fine aggregate: coarse aggregate.. if we mention m10 concrete, it means that the concrete has 10 n/mm2 characteristic compressive strength at 28.
