9*8m slab 1:2:4 ratio use for M20 mix how much cent is
require it will become in cum but i want bags.
Answer Posted / k. bu.babu
basically slab size given;9*8
what is thickness of slab?
O.k Assume thick:0.100 m
volume of concrete=9*8*.1=7.2 Cu.m
dry materiels coeff. =1.52
M20 mix 1:2:4
cement=1.52*(1/(1+2+4))*1440=312.68 kgs.=6.25 bags
total bags required to volume=7.20cum*6.25babgs=45bags

5. Two long boundary walls run parallel to each other at a center to center distance of 1 meter apart. The width and height of the first wall are 0.30 m and 2.5m respectively. While those of the second are respectively 0.18m and 3.5m. Plot the distribution of vertical stress intensity due to walls on a horizontal plane, 1m below ground level. The walls have negligible depth of foundation and are made of brick masonry (y = 19.2 kN/m cu)
