how much quantity of blocks, cement and sand is required to
complete 1sq.m of CC Hollow blockwork. Size-16"x8"x8". Also
what is the cement sand ration commonly used?
Answer Posted / balamurugan
1.Qty of Hollow block is 11 to 12 Nos/ sqm
2.For 9" wide wall Cement sand ratio is 1:6 & 4" wide wall
Cement sand ratio is 1:4.
Volume of mortar/Sqm = (No of Blocks required for the size
of without mortar thick -No of Blocks required for the size
of block including mortar thick)x No of Blocks required for
the actual size of block
For 9" wall
No of Blocks required for the size of without mortar
thick=1/(0.40*.20*.20)=62.5
No of Blocks required for the size of block including mortar
thick= 1/(0.41*.21*0.21)=53.31 Nos
Volume of mortar/Cum= [62.5-55.31]x[0.4x0.2*0.2]
=0.115 Cum
Add wastage 30% extra
Volume of mortar/Cum= 0.115*30% =0.150Cum
Cement sand calculation/Cum of Block work:
Ratio 1:6
Cement =[1/7*1440]*.150 =31Kg
Sand =[(6/7)*.15]=0.129Cum =4.55 Cft
Cement sand calculation/Sqm of Block work:
Ratio 1:6
Cement =[1/7*1440]*.15*.23 =7.13Kg
Sand =[(6/7)*.15*.23]=0.03Cum =1.05Cft
