Jul 26, 2017 · Total volume of 35 blocks required = 0.502 m 3. Let the number of wheel barrow trips of sand be x. Hence, (volume of 1 bag of cement) + (Total volume of sand) = Volume of 35 blocks Hence, 0.03472 + x(0.065) = 0.502 m 3 On solving, x = 7.1889 unheaped wheelbarrow trips of sand The volume of sand required to make 35 blocks = 7.1889 × 0.065 = 0.46728 m 3

In all cases the sand should be clean, free of organic material, be well graded (a variety of sizes) and not exceed 3mm of silt in the sedimentation test. In most cases, particle size should not exceed 3mm as the mortar will be "harsh" and difficult to work with. Lime mortar is typically mixed 1 part lime to 3 of sand

Cement : Sand : Aggregate (in Kgs) is 50 kgs : 115 kgs : 209 kgs (by weight) Water required for the mixture = 27.5 kgs. Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum

So, Sand required = 0.072*1600 = 115 kgs. and Aggregate required = 0.144*1450 = 209 kgs. Considering water/cement (W/C) ratio of 0.55. We can also arrive at the Water required = 50*0.55 = 27.5 kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 27.5 kgs of water to produce M20 grade concrete
