The objective of the present study is to investigate high-strength recycled coarse aggregate-based geopolymer concrete (HRGC) using recycled coarse aggregate and ultra-fine ground granulated blast furnace slag (UFGGBS). The current investigation is split into two phases. In Phase 1, geopolymer recycled coarse aggregate grades (GRM), GRM70, and GRM80 are developed with partial replacement of GGBS with UFGGBS. The optimization of UFGGBS is done through workability and compressive strength (CS) for both grades at 7 and 28 days. In Phase 2, the Tensile strength and Flexural strength are compared with limiting values of conventional concrete as per the IS 456:2000 guidelines. The results showed that, as the amount of UFGGBS content increased, the workability of both grades of concrete declined with an increase in CS. At 7 days, GRM 70 and GRM 80 have achieved a CS of 82-86%. Target strength for 28 days was attained at 100% replacement of UFGGBS for both grades. [ABSTRACT FROM AUTHOR] |
