Answer Posted / nadim shaikh
take brickwork as 100 percent then deduct the mortar
for e.g
6 " wall dimension 10' x 10'
10 feet divided by numbers of mortar layer which will be decided by dividing it by brick laying format for stretcher bond it will be
10' / .33 (4 inch = .33[4/12])
=30 numbers + 1 = 31 ( this was for vertical )
now for horizontal
10'/.75 = 13+1 = 14 joints
now
10' x .5 x .08 ( dimesion of mortar laid in horizontal direction) = 0.4 x 31 joints = 12.4 cu.ft
&
10' x .33 x .08 ( dimension of mortar laid in vertical direction) =0.264 x 14 joints = 3.7
add both i.e 12.4 + 3.7 = 16.1 cu.ft
if 10' x 10' x 6" = 50 cu.ft is 100 % the how much percent will be 16.1 of 50 cu.ft ..
16.1/50x100 = 32.2 say 33%
wooah .. that was quite a lecture
