River Sand : M Sand: Excessive and illegal quarrying of Natural sand at river beds, resulting in soil erosion and danger to the reservoir structures : 100% replacement to River sand and & It is One of the hi-product of aggregates : Scarcity due to ban on quarrying activities near the river bed by the Govt. to prevent depleting of natural resource

Feb 29, 2016 Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials

Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material

Jan 20, 2017 M Sand or Manufactured sand is an Eco-friendly & economical alternative for river sand, which has become widely popular for use in all constructional purposes. It is manufactured by crushing huge rocks & boulders to fine sand particles. Three different types of m sand are manufactured which fulfill the Indian Standards set by the BIS

Only sand manufactured by V.S.I. Crusher is cubical and angular in shape. Sand made by other types of machines is flaky , which is troublesome in working. There is no plasticity in the mortar. Hence the mason are not ready to work with machine made crushed stone sand. For the same reason inferior river sand may be used
