1 cubic meter contains 500 bricks
The Standard size of the 1st class brick is 190mm

1 Newton = o.101971 kg
1 mm2 = 0.01 cm2
1 cm2 = 100 mm2
1 mm2 = 20 N
100 mm2 = 2000N
1 cm2 = 2000N
2000 N = 203.942 kg
So 20 N/ mm2 = 203.942 kg / cm2
RATIO IS 1:1.5:3
then volume is 1+1.5+3=5.5 and the total volume
for using mix=1.57 m3 then cement required=1/
