Formula=Volume*Density of material
Add- Shirinkage-35%to40%
Volume= plastering volume+Depression,joint&Wastage
Density=Cement-1440Kg/m3,Sand-1600Kg/m3
Shirinkage-35%to40%
Depression,joints&Wastage normally-20%of plastering Volume
Cement=(1/6*0.11124*1440)+(1/6*0.11124*1440)35%=
Sand=(5/6*0.11124*1600)+(5/6*0.11124*1600)35%=
