Experimental Investigation of Basic Oxygen Furnace Slag (BOFS) As Fine Aggregate with Partial and Full Replacement of Natural Sand for Use in Masonary Mortar

This experimental research work investigates the possibility of utilizing Basic Oxygen Furnace Slag which was taken from Lloyds Steel Industry Wardha as a sand substitute in cement mortar. The natural sands which are used in this study are local Sand. In this investigation, BOFS at 0, 25, 50, 75 and 100% replacement to natural sand for constant w/c ratio of 0.5 is considered. The work is extended to 100% replacements of natural sand with BOFS and Cement mortar mix 1:5, 1:4, 1:3 by weight were selected. The w/c ratio was taken as per standard consistency test of cement. For compressive strength test 2 samples were tested for 7, 14 and 28 days for all the replacements. The study gave comparative results for mortar compressive strength test. The experimental results obtained show that fully substitution of ordinary sand by slag gives better results in both the sands from this study it is observed that BOFS could be utilized fully as alternative construction material for natural sand in mortar applications for good compressive strength result.
