how much quantity of cement and sand required for
construction of 10 cum brick work( Brick size
3"*4"*9"(Standard size ) an d for 10 cum construction of SSM
(Size stone masonary) with Cm 1:6 for both.

Answer Posted / sjtbehera

you are given 3”x4”x9” standard size of bricks
After placing mortar it became- 4”x5”x10” =
10.16cmx12.7cmx25.4cm
No of bricks are required=
10/.106x.127x.254=3069 nos
The size of brick without mortar= 3”x4”x9”=
7.62cmx10.1cmx22.8cm
Then net mortar required =10-(3069*.076*.101*.228)
= 4.62cum
Due to frog filling, brick bonding course and
wastage add 15%
Volume of wet mortar= 4.62+4.62x15%=5.30cum
When dry increase this qty. by 1/3rd=
5.30+5.30x1/3=7.06cum
Ratio is =1+6=7 cement = 7.06/7= 1.06 = 29 bags
Sand= 7.06*6= 42.36cum
