Answer Posted / ar. g.s. rehal
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.
volume of 374 bricks= 374 x 0.00198 = 0.74052cum
Cement Mortar required for 1cum = 1 - 0.74052cum.
= 0.259 cum.
Say 0.26 cum
Add 15% for frog filling and wastage while execution.
.26 x 15/100 = 0.299 cum
Vol. of wet mortar = 0.299 cum.
Vol. of dry mortar( increase by 30% ) 0.299 x 30/100 =0.0897
0.299 + 0.0897 = 0.388 cum.
For CM of 1:6 (1 + 6 = 7)
Qty. of cement for 1cum = 1/7 x 0.388
= 0.055 cum.
Qty. of sand for 1cum = 0.055 x 6
= 0.330 cum.
Qty. of cement for 10cum =10 x 0.055
=0.55 cum.
Qty. of sand for 10cum = 10 x 0.330
= 3.30 cum.
