manufactured sand instead of natural river sand in making concrete. m-sand is obtained by crushing the natural granite stone in the vertical shaft impact crushers and screening the output form the fine aggregates of size less than 4.m. some studies has been reported the effect of m-sand on strength and durability properties ofhammer mill has the advantage that the rotatable hammers will recoil backwardly if the hammer cannot break the material on impact. one significant problem with hammer mills is the wear of the hammers over a relatively short period of operation in reducing dirty products which include materials such as nails, dirt, sand, metal, and the like.types of sand & classification of sand. followings are the classification of sand: based on the grain size of the particle, sand is classified as fine sand, medium sand, and coarse sand based on origin, sand is classified as pit sand, river sand, sea sand, and manufactured sand.
generally consist of natural sand or crushed stone with most particles smaller than mm coarse aggregates consist of one or a com-chapter aggregates for concrete bination of gravels or crushed stone with particles predominantly larger than mm and generally between 9.5 mm and 37.5 mm in now, we are discussing the alternative of sand. surkhi is one of the artificial fine aggregate replacing sand. surkhi is a powdered form of over burnt broken brick or clay balls. the name surkhi is derived due to its reddish colour. It shows pozzolanic properties and is composed of about of silica by weight. It is also called as western management, llc operates residential communities that include manufactured homes, apartments, and recreational vehicle parks. the manufactured home communities offer residents the choice of renting, purchasing, or renting to buy their homes.
