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.

Let the size of brick be 230mm x 115mm x 75mm
Vol. of brick( w/o mortar) = 0.00198 cum.
Thk. of mortar be 12mm.
vol. of brick with mortar = 242mm x 127mm x 87mm
= 0.00267 cum.
No. of bricks in 1 cum. with mortar = 1/0.00267
= 373.99
Say = 374 bricks.
Cement Mortar required = 1-( 374 x 0.00198)cum.
= 0.259 cum.
Say 0.26 cum

Add 15% for frog filling and wastage while execution.
Vol. of wet mortar = 0.299 cum.
Vol. of dry mortar( increase by 30% ) = 0.388 cum.

For CM of 1:6

Qty. of cement = 1/7 x (1440 x 0.388)
= 0.055 cum.
Qty. of sand = 0.055 x 6
= 0.330 cum.

If the brick work is required to .

convert into Sqmt
1) for 230mm ; 0.23 1070.39
2) for 115mm ; 0.115 535.19

lets the take size of brick is .230*.115*.075. now calculate
the quantity for 10 cum.

Area of one brick without mortar -0.00198375 Cum
No of brick in 10 cum= 10/0.00198375 (Area of bricks).
=5041 nos of bricks.

now calc. the bricks quantity in 10 cum with mortar.

lets take the mortar used 10mm in brickwork then
size of brick will be taken with mortar is =.240*.125*.085=
0.00255 (Area of one brick with mortar).

now in 10 cum brickwork no of bricks calculated with mortar
is=10/0.00255 =3922 nos

calculate the mortar in cum= bricks without mortar- bricks
with mortar= 5041-3922=1119 nos
Now area of brick without mortar is .230*.115*.075*1119=2.22cum

now 15% for frog filling and wastage taken in acc.

=2.22+2.22*15/100=2.55 cum

Dry volume is the 1/3rd of wet volume of mortar=
2.55+2.55/1/3=3.40 cum.

now the ratio is 1:6=7

3.40*14%=.486 cum cement
3.40*86%= 2.92 Cum Sand

=.486/.0347= 14.01 bags/10 Cum
= 14.01*6=84.06 Bags/10 Cum

No of bricks = 500 [5(Stredger face with 10mm CM)*10(Header face with 10mm CM)*10(Header face with 10mm CM)]
Volume of mortar required = 1-500*0.19*0.09*0.09
= 0.2305 cubic metre
Cement required for 1:6 = (0.2305*1440)/7
= 47.41 Kg (Approx. 48 Kg)
(Density of cement 1440 Kg/cu.m)
Sand required = 284.5 Kg (Approx. 288 Kg)

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

Factor of safety for steel should be based on its yield stress or its ultimate stress and factor of safety for concrete should be based on its ultimate stress or its yield stress?
