Abstract

Abstract: This paper investigates the influence of granite waste (GW) on the abrasion resistance and sorptivity characteristics of SCC as a replacement of fine aggregate (or river sand). GW was incorporated to replace fine aggregate in the amount of 0–100% with an increment of 20%. Total of six SCC mixtures was designed by maintaining a constant powder content of 545 kg/m 3 and water to powder ratio of 0.37. Slump flow, T500 time, V-funnel time, J-ring, and L-box tests were performed in the fresh state, while compressive strength, abrasion resistance and sorptivity tests were performed in the hardened state. Satisfactory workability properties of SCC mixtures were found on the incorporation of GW up to 80%, confirming to EFNARC standard. The compressive strength and abrasion resistance properties of SCC mixtures increased on the incorporation of up to 40% of GW and up to 60% of GW respectively. Also, better endurance capacity to the ingress of water was witnessed on the incorporation of up to 40% of GW. It was thus concluded that GW (up to 40%) could be prominently used in the production of SCC without compromising its hardened characteristics.
