Question { SAPL, 2958 }
how to find the cement and sand quantity for wall plastering
Answer
plaster = suppose 12mm palster
consider 1 sqm ratio is 1:6
volume of concrete= .012x1= .012cum ( per 1sqm)
incrase 20% for joint, filling and wastage=.012*20%=.0144
calculate 1/3rd of mortar when
dry= .0144*1/3+.0144= .0192cum
summation of ratio = 7
cement= .0192/7=.00274cum
= .0789bags
sand= .00274*6=.0164cum
this formula applied for 6mm and 20mm
