Effect of tile aggregate and flyash on durability and mechanical properties of self-compacting concrete

Effect of tile aggregate and flyash on durability and mechanical properties of self-compacting... Self-compacting concrete (SCC) increases the working conditions and qualities because of the extraction of compaction in construction areas. However, the loss of strengths and density are high in concretes at different attacks. Therefore a novel Spider Monkey-based Loss Percentage Optimization (SMbLPO) framework has been developed to optimize the percentages of losses on concrete. Moreover, to increase the SCC strength, broken tiles and fly ash were selected as partial replacement materials that are SSC-M30 and SSC-M40 grades were selected for this study. Furthermore, the selected mix percentages for SSC-M30 and SSC-M40 are 0–40% of fly ash and broken tiles as a partial replacement with equal intervals. However, as per the European Federation of National Associations Representing for Concretes (EFNARC) standards, the fresh and hardened properties of concrete were evaluated. From the result of hardened properties, the optimum mix replacement was selected, and the results demonstrated that the 30% replacement was the optimum mix in both grades. In addition, the optimum mix specimen’s durability was tested by chemical attack tests like acid attack, alkali attack, and sulphate attacks for 28 and 90 days.

Abstract

Self-compacting concrete (SCC) increases the working conditions and qualities because of the extraction of compaction in construction areas. However, the loss of strengths and density are high in concretes at different attacks. Therefore a novel Spider Monkey-based Loss Percentage Optimization (SMbLPO) framework has been developed to optimize the percentages of losses on concrete. Moreover, to increase the SCC strength, broken tiles and fly ash were selected as partial replacement materials that are SSC-M30 and SSC-M40 grades were selected for this study. Furthermore, the selected mix percentages for SSC-M30 and SSC-M40 are 0–40% of fly ash and broken tiles as a partial replacement with equal intervals. However, as per the European Federation of National Associations Representing for Concretes (EFNARC) standards, the fresh and hardened properties of concrete were evaluated. From the result of hardened properties, the optimum mix replacement was selected, and the results demonstrated that the 30% replacement was the optimum mix in both grades. In addition, the optimum mix specimen’s durability was tested by chemical attack tests like acid attack, alkali attack, and sulphate attacks for 28 and 90 days. The fitness of spider monkey reduces the loss percentages by tuning the parameters in MATLAB. After tuning of concrete cubes strength and density, SMbLPO was implemented to optimize the loss percentages mathematically. Moreover, the obtained results are compared with other existing specimen’s strengths, and the result demonstrated that the presented specimens had attained higher strengths.
