how do we calculate quantity of cement , sand and
aggregates in 1 m3 of M30 grade concrete ?
Answer Posted / sunil kumar yadav
Taken the ratio-1:1.5:3
cement-1
sand-1.5
metal-3
so ratio will be for mixing-1+1.5+3=5.5
Totals ingredients forusing to=1.54/5.5=o.28
cement solution=0.28 cum
send=0.28×1.5=0.42 cum
(1.5 is a maximum proportion)
metal=0.28×3=0.84 cum
(3 is a maximum proporties)
1 cum cement concrete ratio is 1:1.5:3
cement=0.28 cum
Sand=0.42 cum
metal=0.84 cum
so cemenbbage will be =50/1440=0.0347
(1440=unit wait of cement & 50=wait of 1bage cement)
so cement bags will be=0.28/0.034=8.24 bage.
