How to find quantity of cement mortar?
I want to know the req quantity of cement for plastering 300
sft in final coat with 12 mm. Any math involved? Plz help
Answer Posted / er. jawed
Since area to be plastered = 300sft = 300/10.76 =27.88 sqm
qty of mortar =27.88*.012 = 0.335
now increase this qty by 20% for filling of joint, followed
by 1/3rd of initial qty (i,e; 0.335)which is equivalent to
dry mortar qty
Now, qty of mortar = 0.335+0.20*.335+1/3*0.335 = 0.514 Cum
for mortar Ratio 1:4 , sum of ratio =1+4 =5
Qty of Cement =.514/5 = 0.1028 Cum , (2.96 = 3 Bag )
as 1cum cement =28.8 Bag
Qty of sand = .1028*4 =0.4112 Cum = 13.27 Cft
Hope this will be helpfull for you
