Utilization of marble waste as fine aggregate in the composition of high-performance concrete containing mineral additions

Abstract

This study investigates the effect of adding marble waste (MW) as fine aggregate on the properties of high-performance concrete (HPC). To achieve this objective, 10%, 20%, 30%, and 40% of MW fine aggregate were substituted for ordinary fine aggregate in the composition of HPC mixtures containing silica fume and ground blast furnace slag. The fresh properties were studied using slump, fresh density, and air content tests, while the hardened properties were assessed using compressive and flexural strengths, ultrasonic pulse velocity, water absorption, and chemical acid attack tests. The results obtained revealed that the addition of MW fine aggregate significantly improved the properties of HPC and increased its resistance to chemical acid attacks. The composition-based ground blast furnace slag containing 40% MW fine aggregate outperformed all other compositions, increasing compressive strength by 30.98%.
