Strength and Durability Assessments of Induction Furnace Slag - Quarry Dust -Based High Performance Self - Compacting Concrete

Abstract

Induction furnace slag (IFS) and quarry dust (QD) were reported as good materials in making ordinary concrete. Studies were not done on utilizing IFS and QD as constituents of high-performance-self-compacting-concrete (HPSCC). This study aims at assessing the effects of induction furnace slag and quarry dust on the strength and durability of high-performance self-compacting concrete. Strength tests including compressive, flexural, split tensile, rebound hammer tests were conducted on HPSCC. Likewise, durability tests including water absorption, total porosity and electrical resistivity tests were conducted. IFS at 0 % to 50 % (at 10 % intervals) replacement with Portland cement was used. Also, the optimum IFS content was combined with QD at 0 % to 50 % (at 10 % intervals) replacement with river sand. The results revealed an increment in strength up to 20 % IFS, 50 % QD with a rise of 15.34 % compressive strength over the control. The durability improved up to 20 % IFS, 60 % QD with a rise of 16.86 % electrical resistivity over the control. These showed that IFS and QD can be used for the production of HPSCC.
