The specific gravity of concrete material is as follows: cement = 3.15, sand = 2.6, coarse aggregate = 2.6. The assumed percentage of entrained air is 2%. 1:1.5:3 The mixing ratio of the dry volume of the material can be expressed by mass:- cement = 1 x 1500 = 1500 sand = 1.5 x 1700 = 2550 coarse aggregate = 3 x 1650 = 4950.

Since Sand is usually measured in cft = 0.0133 X 35.3147 = 0.47 cft = 21.5 Kg. Ans :- Cement consumption in 12mm thick plaster 1:5 for 1m2 plastering of brick wall is 0.077 bags (3.8 kg) cement. Cement consumption for 1m2 = 3.8 kg. So cement consumption for 10m2 = 38 kg. Cement consumption for 100 m2 = 380 kg.

Concept: i) For Wet volume of concrete = 1 m 3. ii) Dry volume of concrete should be taken to be 54 % more than its wet volume. iii) Concrete ratio = 1 : 2 : 4, which implies for 1 cubic meter of concrete contains 1 part cement, 2 part sand or fine aggregates and 4 parts aggregates or coarse aggregates.

One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft. Aggregate required = 209/0.167 = 1251 kgs …

Nowadays, we typically use a 1:2:4 mix ratio when building a reinforced concrete single-story house. As a nickname, we can call this mix M15 grade, which comes from its corresponding 15 MPa compressive strength.If we want to build a 2-story house, we would need a stronger mix like the M20 grade mix, which follows a 1:1.5:3 mix ratio.. …

According to Abram's Law water-cement law, lesser the water-cement ratio in a workable mix greater will be the strength.
