M-Sand is manufactured sand by crushing aggregates produced from hard granite stone which is cubically shaped with grounded edges, washed and graded with consistency to be used as a substitute of river sand. Vasthu Shastra says building material must be free from traces of human body or animal. M-sand is free of such material and is produced by crushing hard granite stone when compared to river sand that is produced naturally from weathered rock.

The superior shape, proper gradation of fines, smooth surface texture and consistency in production parameter of chemically stable sands provide greater durability and higher strength to concrete by overcoming the deficiencies like segregation, bleeding, honey combing, voids and capillary. Builders say they are discouraging the use of river sand in constructions and maximising the use of m-sand for the same

River sand is one of the materials left by the erosion of various forms of rocks. To be described as sand the individual grains must be between 0.06mm and 2mm. If the grains are smaller the material is silt, larger and it is gravel. The colour of sand is determined by both its parent material and any additional materials, such as silt or minerals, that may be present.

When viewed in close-up the granules of river sand are distinctly rounded from rolling and cascading down riverbeds. Because of the rounded nature of the particles, lots of tiny gaps are formed, even when compressed, and that creates one of the desirable properties of this sand – good drainage. You will find both the coarse and fine varieties are washed and clean.

Crushed stone is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from gravel which is produced by natural processes of weathering and erosion, and typically has a more rounded shape.

Crushed stone is one of the most accessible natural resources, and is a major basic raw material used by construction, agriculture, and other industries. Despite the low value of its basic products, the crushed stone industry is a major contributor to and an indicator of the economic well-being of a nation. The demand for crushed stone is determined mostly by the level of construction activity, and, therefore, the demand for construction materials.
