· Yes. Adding sand to compost is a great way to add bulk while also improving aeration and drainage. Some gardeners opt to add sand directly to their active compost piles. Others mix the sand and compost immediately before adding it to their gardens. When mixed, sand and compost closely resemble traditional potting soil.
Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample; W B is weight of fraction passing the appropriate sieve
However, maximum allowable limit of material finer than 75 µm particle is 4% for natural sand, 9% for crushed rock sand for use in heavy duty floor finishes and 16% for crushed rock sand in normal use(Ref 3). Coarse aggregate is defined as aggregate mainly retained on 5mm sieve.

As we know 1m3 = 35.3147 cft and density of River sand is 1710 kg/m3, weight of 1 cft river sand = 1710/35.3147 = 48.5 kg, so 1 CFT river sand weight is 48.5 kg. 1 CFT M sand weight in kg. M sand is artificial or manufactured sand by crushing of granite stone in crusher mill. It is partial replacement of river sand used in construction line.
Manufactured Sand. Our Manufactured Sand can be kiln dried. It creates more reliable and consistent cement and mortar mixes compared to river sand. Manufactured Sand is also a superior alternative to decomposed granite or paver sand. It lacks the impurities found in river sand and is stronger than decomposed granite, so it will last longer.
