Strength and abrasion performance of recycled aggregate based geopolymer concrete

This experimental work evaluated geopolymer concrete containing fly ash and slag by partial replacement of natural coarse aggregate (NCA) with recycled (RCA) to manufacture environmental-friendly concrete. The proportion aggregates considered consists 10%, 20%, 30%, 40% the total amount. Also, a steel fiber ratio 0.3% was utilized. mechanical properties abrasion resistance ash/slag-based were then assessed. Majorly, strength samples decreased increase RCA content. gave 28.3% lesser compressive 24% lower splitting tensile than NCA at one year. flexural specimens reduced 35% (from 5.34MPa 3.5MPa) incorporation RCA. 30% caused 23% 22.6% reduction in 56 days year, respectively. not significantly (less 10%) inclusion up 30%. Furthermore, wear thickness every sample less 1mm. 20% produced either insignificant or better results compared reference mixtures. As result, it that combination leads an eco-friendly mix acceptable short long-term engineering would lead sustainability production utilization sector.
