Total quantity of ingredient materials of cement concrete maybe taken as 152 Cu m for 100 cu m.

Approximate method of determining the quantity of materialsfor 10 cu m concrete is to divide 15.2 by the sum of thenumerals of the proportion of the materials which gives the

quantity of cement in Cu m. To find the materials for 10 Cu m of cement concrete of 1:4:8

proportion, Cement = 15.2/1+4+8=15.2/13= 1.17 cum=say 1.15 cu m.

Sand = 1.15x4=4.60

Bajri= 1.15x8-9.20 cu m.
