BRICKS & MORTER CALCULATOR

EXAMPLE WITH CALCULATION STEPs:

(A) Single Brick size = One brick (Length x Breadth x Height) in m = 0.230 x 0.115 x 0.075 m = 0.00198 cum
(B) Total Brickwork Quantity in Cum  = Wall (Length x Breadth x Height) in m = 1x1x1 =1 cum
Mortar Ratio = Cement:Sand = 1:6(C) Dry volume factor of mortar = 1.33
(D) Mortar Thikness in m=10mm = 0.01m
(E) Brick size with Mortar = 0.240 x 0.125 x 0.085 m = 0.00255 cum
(F) Brick Required = (E) / (B)= 1 / 0.00255 cum =  392.15  Nos
(G)  Total Brick Volumn = (F) x (A)= 392.15 x 0.00198 = 0.78 cum
(H)  Mortar Volumn = (B) - (G)= 1 - 0.78 = 0.22 cum 
(I)  Mortar Wet Volumn = (H) x (C)=  0.22 x 1.33 = 0.2926 cum 
(CV) Required Cement Volume in cum =  (I) x (Cement Ratio/Sum of Ratio)= 0.2926 x 1/(1+6) = 0.425 cum Cement in Bag = (CV) / 0.034722 = 1.22 Bags* Volume of 1 Bag Cement is 0.034722 Cum
(SV) Required Sand Volume =  (I) x (Sand Ratio/Sum of Ratio)= 0.2926 x 6/(1+6) = 0.2548 cum Sand in Cft = (SV) x 35.3147 = 9 Cft* 1 m3 = 35.3147 Cft

FAQs: 

For 125mm of Half Brick Work put Thickness 0.125
Wet volume of plaster mix is 33 % higher than dry volume so, When we calculate the mix proportion of  plaster it should be multiplied with 1.33, its call Dry Volumn Factor of Mortar
This is the Volumn ratio of mixing plaster, This ratio should as per your plaster grade i.e. -   Morter standard thickness 10 to 16 mm,  & Ratio for 250 mm wall 1:6, 125mm wall 1:4
