how do we calculate quantity of cement , sand and
aggregates in 1 m3 of M30 grade concrete ?
Answer Posted / subilash .s(civil engineer)
for designing 1m3 concrete of M25 mix the ratio is 1:1:2
for calculating cement,sand and course aggregate ,
cement= 1/(1+1+2)=.25
density of cement =1440kg/m3
cement required for this mix=1440*.25=360kg=6bags+10kg
sand=1/4=.25m3
course aggregate=1-.5=.5m3
this methode of designing is known as volume batching ,this
methode will be ues to design mixes upto m25.
