plz tell.. how can we find weight(in kg) of 1 cum of m20
mix..? how can we find the ratio of cement sand and
agregate on site i.e if we given some amount of m20 mix
then hw we find the ratio..?
Answer Posted / ganesh
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"

A 16 pile group, consisting of diameter concrete piles, were cast in situ in a clayey soil whose unconfined compressive strength is 1100 psf. Each pile is 60 ft long and the pile spacing is 2.5 times the pile diameter.The water table is at the ground surface and saturated unit weight of the clay is 118 lb/cu.ft. using a factor of safety 3 and a reduction factor =0.45, compute the allowable capacity of the piles acting as individuals
