Abstract:
The aim of this paper is to investigate the mechanical properties of self-consolidating concrete (SCC) incorporating ground copper slag (GCS) as cement replacement. Herein, SCC has been produced using GCS as cement replacement by weight ratios of 5, 10, 15, 20, 25, and 30%. The mechanical and durability properties of self-consolidating ground copper slag concrete (SCGCSC) have been investigated in related tests as compressive, flexural, and splitting strengths; unit weight; water absorption; free drying shrinkage; water penetration; and alkali-silica reaction (ASR). Self-consolidating ability tests such as V-funnel, J-ring, slump flow, and L-box were also conducted to ensure the SCCs fulfilled the requirements for self-consolidating. The experimental results indicate that the compressive, flexural, and split tensile strengths of the SCC containing 5% GCS are the highest among the mixtures. However, up to a replacement level of 15%, hardened strengths and unit weights are almost equal to or slightly better than the control mixture.
