Abstract

Concrete that incorporates waste materials as the coarse aggregate, such as electrical insulator ceramic scrap, can have beneficial properties. Because durability is an essential element of concrete performance, researching the durability properties of concrete made from waste materials is essential to ensure its long-term dependability. Permeation characteristics like water permeability or chloride permeability are widely used to evaluate the durability of concrete. This study quantifies the qualities of ingress, chemical assaults, and corrosion of the reinforcing steel to assess the concrete's resistance to several types of degradation, including moisture. It improve the long-term durability of concrete structures while also reducing waste output by creating sustainable concrete technologies and using waste materials as aggregates. For "Green" concrete to be used widely and consistently, it is crucial to keep researching and enhancing its durability qualities. Its usage reliability will also improve as a result of studies into its durability. Permeation features are widely used to gauge the durability properties of concrete. The results of an experimental research on the permeation features (volume of voids and water absorption (ASTM C642-06), chloride penetration (ASTM C1202-10), and sorption of concrete with ceramic electrical insulator waste coarse aggregate, hereafter referred to as recycled aggregate concrete) are compared in this study with cement replacement by silica fume with 0%, 5%, 10%, 15%, m-sand as fine aggregate, and coarse aggregate replacement by ceramic insulator (0% to 100%). From this result experimentally various combination carried out 10% of silica fume and 80% of ceramic insulator better durability properties of concrete. When compared to the control mix, CC MS, the water absorption of the mixture CW80 SF10 was reduced by 3.2%. At 28 days of immersion in (H2SO4), the weight loss percentage for the CW80 SF10 mix is 16% lower than that of the control concrete. After 28 days of immersion in (H2SO4) solution, the identical mix's compressive strength decreased by 4.41%, which is 18.2% less than the control concrete. 1.4% less concrete was immersed in (MgSO4) for 28 days than the control concrete. At 28 days of immersion in (MgSO4) solution, the same mix's percentage compression strength reduction is 8.52% lower than that of control concrete
