If the size of bricks or thinness
of joints if different, the requirement of sand bricks may be worked out as
under :
Sand = M = 1.10 (st/v + 0.10 / st/v + 2.0)
No. of bricks = N = 2.06 / (st/v + 2.0) v
Cement in bags = (M/R) X 28.72
Where S = Total surface area of one
brick,
R = Ratio of mortar mix (I:R)
V = Total volume of one brick neglecting
frog t = thickness of joint.
