| Abstract | ||
| In this study, the optimization of concrete reinforced with iron chips, a waste product from the iron and steel industry was carried out. To this end, the Response Surface Method was used in the experimental design and empirical modelling phases. Genetic algorithm was also used to determine the optimum values. Different concrete samples with water/cement ratios of 0.40, 0.50 and 0.60 were prepared for the experimental studies. During the production of the concrete samples, waste iron chips with different shapes (flat, spiral and mixed) were added to the mix as reinforcement, based on the proportions of 0.25%, 0.50% and 0.75% of the total volume. Compressive strength and ultrasonic pulse velocity tests were performed on the concrete samples prepared in 12 series. Analysis of variance (ANOVA) was used to determine the statistical effects of the parameters on the experimental results. As a result of the study, optimum parameter levels were determined to achieve the desired properties in concrete samples reinforced with waste iron chips. | ||
