摘要：

Production of self-compacting high-strength concrete (SCHSC) needs a colossal quantity of cement, which is perilous for the environment and economy. Researchers are intended to lower down the dependency on this cement and seeking for alternate green materials. The incorporation of industrial by-products together with mineral admixtures has been found suitable to minimize aforesaid problems. This investigation is, therefore, aimed to study the durability performance of SCHSC by comprising silica fume and fly ash (mineral admixture), and waste marble slurry (WMS) as an alternative to cement. The durability of such SCHSC mixes was evaluated by performing water permeability, chloride penetration, carbonation, corrosion, and drying shrinkage tests. X -Ray Diffraction (XRD) analysis was carried out for the microstructural formation of SCHSC mixes. The results revealed that the incorporation of mineral admixture and WMS improved the durability performance of the mixes. The durability parameters confirm the optimal performance of the SCHSC made with 10% of WMS and 15% of fly ash, with 5% of silica fume.
