Abstract:This paper aims to introduce steel slag as a green construction material. The object of the study is to investigate the possibility and effect of replacing natural coarse aggregate in concrete paving block with electrical arc furnace slag (EAFS) to enhance its properties. The effect of different mixing ratios of EAFS on abrasion resistance, compressive strength, and water absorption were evaluated. It is observed that all the mixtures achieved most of the required ASTM C936 limits. The abrasion resistance and compressive strength of the slag-based mixtures showed higher values compared to the control mixture with conventional limestone aggregate. However, the abrasion requirement for interlocking concrete pavers is debated in the light of ASTM C936 standards. A suggested adaptation of the standard specification for solid concrete interlocking paving units, ASTM C936, is argued to consider macrotexture characteristics of the paver surface—ASTM E965 or ASTM E2157—as one of the paving requirements.
