Bending behavior of reinforced geopolymer concrete beams with varying proportions of slag and polyamide fibers in oven and ambient curing

This study examined the impact of different ratios of slag and polyamide fibers on the load deformation behavior of reinforced geopolymer concrete. To achieve this objective, the performance of geopolymer concrete was assessed by varying the ratios of slag-polyamide fiber and the percentage of replacement. Additionally, the utilization of a combination of ambient and oven curing methods in the reinforcing of geopolymer concrete was also examined. Adjustments were made to the ratio of slag in a number of different proportions, including 5%, 10%, and 15% to achieve this purpose. The ratios of polyamide fibers, on the other hand, were chosen to be 1%, 2%, and 3% respectively. This objective was accomplished by producing a total of twelve different mixing ratio samples. A cross-sectional area of 100 mm by 150 mm and a length of 1000 mm were the dimensions that were utilized in the construction of the examples. This was done to achieve the intended outcome. The study investigated the effect of varying the slag ratio while keeping the polypropylene fiber ratio constant. A 10% increase in the slag ratio resulted in a direct improvement of 26% and 45.5% in the load bearing capabilities of R-C-Bs for Ambient and Oven curing, respectively. In addition, it was observed that increasing the polypropylene fibers ratio by 1% during the ambient and oven curing process led to a significant 31.9% and 31.7% enhancement in the load carrying capacity of R-C-B. At the conclusion of the studies, it was shown that strengthening the reinforcing geopolymer concrete significantly benefited from the concrete being subjected to an oven curing method.
