Performance of Fine Aggregates: A Comparative Study on Sands of Goa

Abstract

Natural sand is commonly utilized in the manufacture of cement concrete and mortar. Due to a scarcity of good quality natural sand and the negative environmental effects of extracting natural sand from river beds, various research institutes are researching to identify and characterize alternative materials that can replace natural sand. However, it received attention as a result of the building industry's hue and cry on the resource crunch. Even literature history confirms this fact. The present work brings an insight into the physical properties of sands available in and around Goa. The rheological and mechanical properties of mortar and concrete have a large impact on their durability. The properties of the fine aggregates get influenced significantly by their particle size distribution, specific gravity, and surface roughness to name a few. The chemical characteristics of fine aggregates are frequently impacted by the elastic modulus, mineralogical composition, toughness, and degree of change of the aggregates. Research was done on 5 different type of sands, and their compatibility was evaluated using physical and chemical parameters. The study materials include standard (as per IS650) sand , river sand, manufactured sand, fine silica sand, and coarse silica sand. The properties of all sands are compared with that of Standard sand. The data is more important to the construction industry. The building sector necessitates such a thorough investigation.
