Mechanical Properties of Mortar by Partial Replacement of Slag Sand and Slag to M-Sand and OPC

Abstract

The present study is undertaken to investigate the viability of partially replacing GBFSS (Granulated Blast Furnace Slag Sand) and GGBFS (Ground Granulated Blast Furnace Slag) with M-Sand (Manufactured Sand) and OPC (Ordinary Portland Cement) individually and amalgamated in varied mix proportions. The cement mortar cubes were subjected to compressive strength tests at the end of 3, 7, 28, 56, and 90-day curing. The compressive strength of 30% and 35% mix proportion of individually and blending (GBFSS and GGBFS) was 20.4%, 18.3%, and 5.8% (46.3N/mm², 45.5N/mm^2, and 40.7N/mm²) higher than the reference for 90-day curing. The partial replacement of Slag Sand and Slag to M-Sand and OPC not only eliminates the waste management problems and their impact on the environment but also leads toward sustainable development through the conservation of natural resources.
