ABSTRACT:
This paper focuses on the stress-strain behavior of 25% recycled coarse aggregate-based geopolymer concrete (RAGC). In this study, an 8-molarity concentration of NaOH and an alkaline liquid ratio of 2.5 was used. This study includes the stress-strain behavior along with the Modules of elasticity for the GRM20, GRM30, and GRM40 grades. Tests were carried out on 150 x 300 mm cylindrical RAGC specimens. The test results experimental to theoretical elastic modulus were in good correlation. Stress-strain relations of RAGC under ambient curing conditions were satisfactory.
