Answer / manoj mall

for brick size 230mmx115mmx75mm (1:4) for 1cum
volume of 1 brick= 0.00198
say 12mmtk mortar on brick layer
so vol of brick 0.00267 cum
No. of bricks in 1cum = 1/0.00267 = 375 num bricks
volume of bricks for 1cum = 375x0.00198=0.724 cum
volume of cement mortar 1~0.724=0.26cum
add 15% for wastae=0.3 cum
add 30% for dry mortarof 0.3 cum = 0.4 cum
for cm 1:4 = 1+4=5
qnty of cement 1/5 x 0.4 = 0.08 cum
1 bag of cement = 0.035 cum
0.08/0.035 = 2.28 bag
sand = 0.08 x 4 = 0.32 cum

Answer / ashok yadav

The actual size of brick is 230 mm x 110 mm x 75 mm
Volume of one brick = 0.0018975 cum
For calculation take a wall of size 10.00 mtr long and 3.00 mtr height 230mm thick wall
Volume of wall = 6.90 Cum
No of course with 10mm thick mortar = 3.00/0.085 = 35 coarses
No of bricks in one coarse 10.00/0.24 = 41.67x2 =83 nos
Total no of bricks in wall = 83x35 = 2905 bricks
No of bricks in one cum = 2905/6.9 = 421 Bricks
Total volume of Bricks = 421x0.0018975 = 0.798 Cum
Volume of Mortar = 1.00-0.798 = 0.202 Cum
Add Wastage 15 % = 0.2323 Cum
Add Bulkage dry to wet mortar 25% = 0.29 Cum Say 0.30 Cum
If Mortar ratio is 1:6 then Cement = (0.30/7)x28.8 Bags= 1.23 Bags
Sand = (0.30/7)x6 Cum = 0.0.257 Cum= 9.0 Cft
If Ratio is 1:4 then Cement = (0.30/5)x28.8 Bags= 1.72 Bags
Sand = (0.30/5)x4 Cum = 0.24 Cum = 8.5 Cft
Sand

Answer / suyog patil

for brick size 200mmx100mmx100mm (1:4) for 1cum
volume of 1 brick= 0.002
say 12mm thick mortar on brick layer
so volume of brick=0.00267 cum
No. of bricks in 1cum = 1/0.002 = 500 no. bricks
volume of bricks for 1cum = 500x0.00154=0.77 cum
volume of cement mortar 1-0.766=0.23cum
add 15% for waste=0.26 cum
add 30% for dry mortar of 0.3 cum = 0.34 cum
for cm 1:4 = 1+4=5
quantity of cement 1/5 x 1 x 0.34 = 0.068 cum
1 bag of cement = 0.035 cum
0.068/0.035 = 1.94 i.e 2 bag
sand =1/5 x 4 x 0.34= 0.27 cum

Answer / suneel.p

brick size 0.23*0.1*0.1(1:4)
valum of brisk : 0.0023cum
say 12mm thick mortar or brick layar((0.23+.0006)*(0.1+.0006)*(0.1+.0006)
so volume of brick: 0.00265
no.of bricks in 1cum=1/0.00265=378 no.s
volum of brik for 1cum=378*0.0023=0.869cum
volum of mortar 1-0.869=0.131
add30% for dry mortar of =0.30cum
add 10% for wastages =0.10cum

total volum of mortar =0.40 cum
for c:m =1+4=5
qantay of cemant 1/5*0.4=0.08 cum
1cum of cemant =(1440/50)=28.8bags
=.08*28.8=2.304bags
sand =4/5=0.8*0.4=0.32cum

Answer / a.sanjeeva karna

brick size 0.23*0.1*0.1(1:4)
valum of brisk : 0.0023cum
say 12mm thick mortar or brick layar((0.23+.006)*(0.1+.006)*
(0.1+.006)
so volume of brick: 0.00265
no.of bricks in 1cum=1/0.00265=378 no.s
volum of brik for 1cum=378*0.0023=0.869cum
volum of mortar 1-0.869=0.131
add30% for dry mortar of =0.170 cum
add 10% for wastages =0.013 cum

total volum of mortar =0.183 cum
Say =0.200 Cum
for c:m =1+4=5
qantay of cemant 1/5*0.2=0.04 cum
1cum of cemant =(1440/50)=28.8bags
=.04*28.8= 1.152bags
sand =4/5=0.8*0.2=0.16cum

Answer / er. anil kumar

brick size - .23*.115*.075
1 cum dry volume of mortar- .30
mortar ratio -1:6
for cement-.3*1/7 =.042cum
1 cum of cement - 28.8 bags
for cement- .042*28.8= 1.23 bags
for send - .30*6/7= .257cum

Answer / pradip mahato

Brick size 230mmx115mmx75mm (1:4)
volume of 1 brick= 0.00198cum
say 10mmthk mortar on brick layer
so vol of 1 brick 0.00255 cum
No. of bricks in 1cum = 1/0.00255 = 393 num bricks
volume of bricks for 1cum = 393x0.00198=0.778 cum
volume of cement mortar 1-0.778=0.22cum
add 15% for wastae=0.15 cum
add 30% for dry mortarof 0.3 cum
total=.15+.3=0.45cum
for cm 1:4 = 1+4=5
qnty of cement 1/5 x 0.45 = 0.09 cum
volume of 1 bag cement = 0.035 cum
cement=0.09/0.035 = 2.571 bag
sand = 4/5 x0.45 = 0.36 cum =12.715cft
