The Efficiency of By-product- Based Geo-polymer Concrete

Abstract

Geo-polymer concrete (GPC) and industrial byproducts have developed expeditiously as eco-benevolent substitutes for OPC. Whereas elevated curing temperature is essential. This research studies the applicability of producing byproduct-based GPC cured under ambient temperature. The effect of the incorporation of ceramic squander powder (CSP) and rice husk ash (RHA) is assessed. All the investigated mixtures contain 40% Slag, 10% fly ash (FA), and a 50% combination of CSP and RHA. Four different combinations of CSP/RHA namely; 10/40, 20/30, 30/20, and 40/10 are utilized. w/b ratios; 0.3, 0.4, and 0.45 are tested. Compressive, splitting tensile, and flexural strengths are examined as indicators of mechanical properties. Acid resistance, water absorption, sorptivity, and chloride permeability are evaluated as indicators of durability aspects. The results revealed that the 30/20 combination is optimum in terms of mechanical properties, while, all combinations attained applicable durable properties compared to the control mix with 90% slag and 10% FA.
