Answer / sanjeev saini

wet mortar =100*.015=1.5
dry mortar =1.5*1.2 =1.8
ratio =1:4 (assumed)
sum =1+4=5
sand =4*1.8/5=1.44 cu m (answer)

Answer / kumar navneet

Unit- 1sqm ; take 100sqm
Qty of mortar req to plaster wall= 100sqm x .015m=1.5cum
To make up for uneveness inc by 30% = 1.5+ (1.5x30)/100= 1.95cum
Inc by 25% the total dry volume = 1.95+ (1.95x30)/100
= 2.34 cum
for 1:4 cement sand mortar (Assumed)
Cement = 2.34/(1+4)= 0.468cum
Sand = 0.468 x 4= 1.872cum

Answer / qaisar imtiaz

15MM PLASTER FOR 100 SQ.M
THEN TOTAL AREA IS MEAN 10*10=100 SQ.M
10*10*0.015=1.5 CUM
RATIO =1:3
FOR CEMENT =1.5/4*1=0.375/0.0354=10.60 BEG
FOR SAND = 1.5/4*3=1.125CUM

Answer / abhishek

Length * Breadth

Answer / er. shivam dixit

15 mm plaster for 100 sq. m.
then the total quantity = 1500 cu. m.
let us consider the cement plaster proportion is 1:4
then the total sum of the proportion = 5
total dry mortar required for 1cu. m. = 0.40
the sand required for one cu. m. = (4*0.40)/5 = 0.32 cu. m.
so the total sand required 15mm plaster for 100 sq.m.
= 15*100*0.32 = 480 Cu.m.
