Partial Replacement of Coarse Aggregate with RCA and Cement with Waste Glass Powder & Slag in M30 Rigid Pavement

Abstract

The construction of rigid pavements traditionally relies on natural aggregates and cement, both of which have significant environmental impacts. In recent years, there has been growing interest in utilizing waste materials as alternative components in pavement construction to promote sustainability and reduce the ecological footprint. This study looks into how waste products, like ground granulated blast-furnace slag (GGBFS),waste glass powder(WGP) and recovered concrete aggregates, can be used to make construction more sustainable especially when it comes to cement-based materials used for hard pavements. Reducing CO2 emissions from cement production, encouraging waste recycling, and reducing the use of natural resources were the objectives. Recycled concrete aggregates (RCA) was added to concrete mixes in different weight percentages (0% to 40%) in place of natural aggregates. at order to enhance the mechanical qualities of the concrete, the study additionally investigated the application of both slag and waste glass powder (WGP) as a supplemental cementations material at various percentage. Concrete specimens that had been cured for seven and twenty-eight days were tested for compressive strength, splitting tensile strength, and flexural strength. The findings showed that as compared to ordinary concrete, the strength decreased as the percentage of recycled concrete aggregates increased. But when GGBFS and WGP were added, the strength increased; the mix with 30% recycled aggregate, 28% slag and 27% WGP showed the greatest results. This mix performed exceptionally well in every strength test and proved that using WGP, GGBFS and recycled aggregates lessens the need for Portland cement and natural aggregates, which promotes more environmentally friendly building methods. According to the results, secondary roads can benefit from the use of recycled concrete with GGBFS and WGP since it strikes a balance between sustainability and strength. The study emphasizes how concrete performance for certain applications can be maintained while environmental effect can be decreased.
