Disadvantages of M-Sand. Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete.

impurities, clays, etc., are totally overcome. Manufactured sand is widely used around the world and technicians of major projects around the world insist on the compulsory use of manufactured sand because of its consistent grada-tion and zero impurity. The use of this sand results in dense and cohesive concrete thus increasing the strength and ...

To explore the influence of manufactured sand content on the flexural performance of self-compacting lightweight aggregate concrete (SCLC) beams, five SCLC beams with different manufactured sand dosage have been designed and fabricated for four-point bending tests. The workability and mechanical properties of the concrete …
