5. The cement consumption per 100 sq-m area for 12 mm thick plastering with cement mortar proportion of (1:4) is _____.

[A] 18 bags
[B] 15 bags
[C] 12 bags
[D] 9 bags

Answer: Option C

Area of plaster and 12mm thick, Volume of plaster=100×12/1000 = 1.2 m³
(hardened wet volume)
Add 30% for filling joints of wall, for levelling, for wastage etc.
Add more 25% for dry volume.
So, Volume=1.20×1.30=1.56m³ (Mixed wet volume on site)
So, Dry volume= 1.56 * 1.25 = 1.95m³ (Dry volume of cement mortar)
For CM = 1:4, cement consumption is = 1/5 * dry volume of CM = 1/5 * 1.95 = 0.39 m³ = 0.39/0.0335 bags = 11.64 = 12 bags
