As an approximate 30% dry mortar may be taken. Calculation of Cement and Sand ...
Mix mortar for laying flagstones, flooring, bricks and tiles. Use a ratio of 3 parts sand to 1.5 parts cement. Adding hydrated lime to the mixture will reduce shrinkage cracks. It will also make the mortar more waterproof. If you add lime, the mixture will be 15 gallons of sand, 6.38 gallons of cement
A 3:1 ratio of sand and cement are mixed without the addition of ANY water. None. At all. Not a drop. The resulting powder should be of a uniform colour indicating the sand and the cement are thoroughly mixed. It is then scattered onto the surface of the paving and swept into the joints using a soft brush.
For a given type of cement, aggregates of same type and size, and same methods of mixing, the concrete develops a maximum compressive strength of 380 Kg/cm 2 at a W/C=0.4.. When this ratio is increased to 0.5, 0.6 and 0.7, etc., The resulting batches of concrete show considerably less compressive strength.
Sep 26, 2016 I was going to do a ratio of 9:1 for sharp sand and cement for the dry mix, to a depth of 40-50mm is this ok? or should the ratio be less sand And for the pointing, I was going to leave a 5mm gap between the slabs and then let them set for 24 hrs, and then do another mix of dry mortar, with ratio of 3:1 sand/cement, is this ok.
All of the ratios are based on dry weight. Type of Range of ratios aggregate (cement:aggregate) Sand and gravel 1:8 to 1:12 Limestone 1:7 to 1:12 Pumice 1:4 to 1:6 Cinders 1:6 to 1:8 Slag (expanded) 1:5 to 1:7 Slag (air cooled) 1:8 to 1:12 Clay (expanded) 1:6 to 1:9 5b.
Here, water cement ratio = 0.50. Water Cement ratio = weight of water / weight of cement. Weight of water = 383.04*0.5 = 191.52 kg (ltr) From above method, we can calculate the quantity of sand, cement and water in mortar. Water Cement ratio of different grade of Concrete – Table
