Q1:

For 100 sq. m cement concrete (1 : 2: 4) 4 cm thick floor, the quantity of cement required, is

A 0.90 m3

B 0.94 m3

C 0.98 m3

D 1.00 m3

ANS:B - 0.94 m3

Area = 100 M2.
Thickness = 4 cm = 0.04m.
Volume = 100*0.04 = 4 M3.
Add 54% of Dry vol = 4+ 54/100 * 4 = 6.16 m3.
Cement = 1/7 *6.16 = 0.88 m3.
