what"s the cement, sand, aggregate(consumption) quantity
for 10 cm thick roof slab (1:2:4)

Answer Posted / pradeep tk

as volume-----
for 1 m3 concrete, volume=1m3
propotion=1:2:4

ie, volume of cement=1*1/7

=0.142 m3
volume of sand=2*1/7
=.285 m3
volume of aggregate=4*1/7
=0.571 m3

for this slab we consider 1 m2 of .10m thick
volume of concrete in 1 m2 slab =1*1*.1
=.1 m3
for that volume,,,,,,cement=.142*.1
=.0142 m3

sand =.285*.1
=.0281 m3
aggregate=.571*.1
=.0571 m3
