Difference Between M Sand and River Sand

M Sand:

• M sand is manufactured in factories.
• It is manufactured by quarrying stones, crushing rocks, or larger aggregate pieces into sand size particles in a factory or quarry.
• The shape is cubical and angular, has a rough texture, and is hence better for concrete.
• It has a low moisture content.
• This sand highly recommended for RRC purposes and brickwork

River Sand:

• This is naturally available on riverbanks.
• This is naturally extracted from the riverbanks or river beds.
• The shape of natural sand is rounded and has a smooth surface.
• Moisture is generally present between the particles. Hence, it affects the assumptions of concrete mix designs and the quality of concrete.
• River sand is recommended for RCC, Plastering, and brick block.
