theritically 500 bricks and practically 450 to 480.here
practically means type of skilled mason and labor.it needs
58 kg cement to construct a cumec of brick work of size
19*9*9cm

1cm=35.32 cft
normal size of brick=.75*.375*.25=.0703

morter=35.32*.30=10.59

ratio 1;6=7
1/7*10.59*1.27/1.25=1.54 cement
6/7*10.59*1.27=11.52 cft sand

how amny bricks of size 240 mm X 120 mm X70 mm are required in
100 cubic meter brickwork. How much cement is required at 10
mm masonry and at 4:1 sand cement ratio and how much cubic
meter of sand is required for the above work.

If we know the N - Value of soil and required bearing
capacity how do we know what diameter and length of pile to
be casted?
How can we check whether the dia. and lenght of pile we
have selected are most economical onse?
