Abstract

<jats:title>Abstract</jats:title><jats:p>Using wastes products in concrete contributes towards sustainability in civil engineering construction. Producing high-performance-self-compacting concrete (HPSCC), using induction furnace slag (IFS) contributes positively to the sustainability of concrete technology. Many researchers have developed self-compacting concrete (SCC), but there are minimal investigations reported considering the high-performance in the development of SCC. The aim of this paper is to determine the fresh characteristics of HPSCC, using IFS as a supplementary cementitious material. Tests were conducted on filling ability, passing ability, as well as resistance to segregation of the fresh HPSCCs, containing IFS at percentage replacement of 0%, 10%, 20%, 30%, 40% and 50%. Slump flow and T<jats:sub>50cm</jats:sub> slump flow tests were conducted to determine the filling ability. L-Box test was used to determine the passing ability. V-funnel at T<jats:sub>5minutes</jats:sub> test was conducted to determine the resistance to segregation. The results showed that the slump flow ranged between 652 and 687 mm, the T<jats:sub>50cm</jats:sub> slump flow ranged between 2.59 and 3.97 seconds, the L-box value ranged between 0.81 and 0.95, while V-funnel at T<jats:sub>5minutes</jats:sub> ranged between 1.88 and 3.11. The fresh properties criteria, according to EFNARC were fulfilled, except for few concretes with IFS content greater than 20%. It is therefore recommended that induction furnace slag be incorporated as a supplementary cementitious material (SCM) when producing HPSCC.</jats:p>
