HOW TO CALCULATE QUANTITY OF CEMENT SAND IN PLASTER

Before Starting Calculation of Quantity of Cement, Sand in Plaster Some Assumption to be made:-

1. Assume Size Of Wall on Which Plaster Applied :- 10 Mtr. X 5 Mtr.

2. Assume Thickness of Plaster To be Applied :- 12 mm (It May Be 15mm)

3. Assume Ratio of Proportion :-  1:6

• WHAT IS DIFFERENCE BETWEEN PLASTERING AND POINTING

CALCULATION :-

1. Area on Which Plaster Applied = 10 X 5 = 50 Sqmt.

2. Thickness of Plaster = 12 mm = .012 Mtr.

3. Volume of Cement Mortar Required = Area of Wall X Thickness of Plaster

    = 50 X 0.012

= 0.6 Cum

• WHAT IS THE DIFFERENCE BETWEEN ONE WAY SLAB AND TWO WAY SLAB

( This is Volume of Wet Mortar. Than we Assume Bulking Of Sand = 34% And Wastage of Material 20%. Many of People Use 1.54 As a Constant. This Constant Use for Bulking of Sand & Wastage of Material)

Than Volume of Dry Mix =  1.54 X 0.6

= 0.924 Cum.

• HOW TO CALCULATE NUMBER OF BRICKS IN A WALL

Cement : Sand (Ratio) = 1 : 6

Than Quantity of Cement =  0.924 X (1/7)       (i.e. Total Part = 6+1 = 7 & Part of Cement = 1)

= 0.132 Cum.

No. of Bags of Cement = 0.132/ 0.0347 = 3.80 Bags

(i.e. volume of one bag of cement = 0.0347 cum.)

Than Quantity of Sand = 0.924 X (6/7)            (i.e. Total Part = 6+1 = 7 & Part of Sand = 6)

= 0.792 Cum.
