HOW we can calculate the quantity of sand and cement for 1:4
plastering with a thickness of 12 mm..total area need to be
plaster is 985 sqm

Answer Posted / karthikeyan

1" = 25.4mm so,
12mm = 0.5"
total area = 985 sqm
1 sqm = 10.76 sqft
985 sqm = 10598.6 sqm
10598.6*0.5 = 5299.3 cuft(149.97 cum)
for 1 cum (1:4)1/5*1440 = 288 kg so
149.97*288 = 43191.36 kg
50 kg = 1 bag, so
863 bag cement is required
1 m^3 cement = 1 m^3 sand s0 863kg sand is
required
