Now-a-days good sand is not readily available, there is a need to find some substitute to natural river sand. The practice of replacing natural river sand with M-Sand is taking a tremendous growth M-Sand is produced from hard granite stone by crushing. M-sand can contain larger amounts of fine particles than natural sand, this can affect the strength and workability of the concrete and this fine particles are dumped as a waste by-product called M- Sand dust which cannot be used in any civil engineering applications. Thus, the main objective of this study is to find the suitability of M-sand silt in civil engineering application by conducting tests such as grain size distribution, specific gravity, standard proctor test, permeability test, direct shear and CBR test. Based on the results, the suitability of M-Sand dust for plastering, concrete, pavement, filter media, landfilling and reinforced earth wall backfill are discussed.
