M25=1:1:2
one bag cement = 50 Kg
Density of cement=1440
one bag cement =50*1440=0.034 cum
one cum dry volume cement =1.52
total ratio=1+1+2= 4
Dry volume of cement/ Ratio
=1.52/4= 0.38
cement=1*0.38=0.38
require cement in bags=0.38/0.034(1 bag cement volume)
                      =11.17 bags
Sand=0.38 cum 
stone chip=.38*2= 0.76 cum
