Dear one,
M20=1:1.5:3 Ratio and M15=1:2:4 all the calculation which given above is not as per Standard so pls post the right one because any one of juniors can follow it blindly,
OPC ( Mix ratio of 1:1.5:3 - M20) ORDINARY PORTLAND CEMENT
Volume - 1 + 1.5 + 3 = 5.5
Total volume of ingredients used = 1.57 Since we use volume batching, wet volume of concrete is 1.57 times the dry volume)
Volume of coarse aggregate required "(3/5.5) *1.57 = 0.856 cu.m
=0.856 * 35.314 = 30.24 cu. ft"
Volume of sand required "(1.5/5.5) * 1.57 = 0.428 cu.m
= 0.428 * 35.314 = 15.12 cu.ft"
Volume of cement required "(1/5.5)*1.57 = 0.2854 cu.m
=0.2854 * 1440 = 411 kgs
= (411/50) = 8.22 bags"
