The volume of concrete= 100 * .04 = 4.
10% increase for the unevenness + 50% increase for dry volume =4*1.1*1.5 = 6.6cum,
Cement=6.6/(1+2+4).

Cement=6.6/(1+2+4).

The correct answer is 94.
Volume of wet concrete in 4cum.
Volume of dry concrete is=4*1.54( constant),
Total v= 6.61.
Quantity of cement = 1/7 * 6.61 = 0.94.

Area = 100 sq.m.
Thk= 4 cm = 0.04 m.
V=A*Thickness = 100 * 0.04 = 4 cu.m.
Extra increase for dry volume = 1.55 * 4 = 6.20 cu.m.
Qty of cement in(1:2:4) = 6.20* 1/(1+2+4) = 0.88 cu.m.
Thk= 4 cm = 0.04 m.
V=A*Thickness = 100 * 0.04 = 4 cu.m.
Extra increase for dry volume = 1.55 * 4 = 6.20 cu.m.
Qty of cement in(1:2:4) = 6.20* 1/(1+2+4) = 0.88 cu.m.

Hi.
Please tell me, How to calculate the Qty of cement 0.940 m^3 ?

100 * .04=4cu.m of wet concrete.
To produced 1cu.m of concrete 1.54cu.m of dry concrete required.
1.54 * 4 = 6.16cu.m
6.16/1+2+4 = .88 cu.m of cement reqd.
.88 * 1440 (density of cement)=1267.2 kg.
Or,
1267.2/50kg = 25.34=26 bag of cement.

For 4cm thick flooring constant of rate analysis is 6.6.
6.6/(1+2+4) = 0.94285,
for 2.5cm thick flooring 4.125.
6.6/(1+2+4) = 0.94285,
for 2.5cm thick flooring 4.125.

1.54 is the conversion factor to convert wet to dry mix and additional they take 10% for unevenness & loss. So, total 1.64.
