How to calculate the Cement and Water quantity for cement grout
If the proportion of
grout is given, the short-cut calculation has been developed, called as 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 above formula,
we can calculate the quantity of cement bags and water in litres instantly with
simple division or multiplication.
For example….
For Proportion
of grout is 1:0.5 for 1000 Litres grout, the Quantity of Cement and Water
have 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 technique.
Note- These formulas
are for plane grout, no chemical and add mixtures are added.
