Abstract : Silico manganese is an essential alloy in the manufacture of steel which imparts hardness and strength and works as an oxidizing agent. A large amount of non bio-degradable slag is produced during the manufacture of the alloy, which was considered for use in cement mortar in the form of manufactured sand as fine aggregates. The use of SiMn slag requires detailed knowledge of its chemical, mineralogical, pozzolanic, volume expansion and strength properties in addition to reaction kinetics which plays an important role in the final valorization of slag as pozzolanic material. This research paper discusses the experimental investigations into thirteen proportions of different sands (i.e. standard sand, manufactured sand and local sand), fly ash and cement in the mix. The results of compressive strengths at 3,7,14 and 28 days were compared. The manufactured sand particles have irregular shapes, and the sand contains more fine particles contributing to improved compressive strength as compared to natural sand. It was observed that manufactured sand mortars have compressive strengths close to standard sand mortars and natural sand mortars.
