How to calculate the cement and water quantity for cement grout
If the proportion of
grout is given, the shortcut calculation has been developed, called the CBS
FACTOR; the calculation has been shown below…….
|
Cement Quantity= Grout in Litres/CBSFACTOR
(Cement Qty. in
Bags) Water Quantity = Cement
Quantity X proportion of water (Water Qty. in litres) |
Where,
CBS FACTOR = 65.66 for 1:1 (one cement and one water)
= 60.66 for 1:0.9 (one cement and 0.9 water)
=55.66 for 1:0.8 (one
cement and 0.8 water)
=45.66 for 1:0.6 (one
cement and 0.6 water)
=40.66 for 1:0.5 (one
cement and 0.5 water)
From the above formula,
we can calculate the quantity of cement bags and water in litres instantly with
simple division or multiplication.
For example….
For a proportion of grout of 1:0.5 for 1000 litres of grout, the quantity of cement and water has been calculated…
Cement Qty. = 1000/40.66 = 24.59 bags X 50 = 1229.71 kgs
Water Qty.
= 1229.71X0.5 = 614.85 Litres
The above calculation
can be verified using mathematical techniques.
Note- These formulas
are for plane grout; no chemicals and additives are added.
