Sustainable Concrete with GGBS as Partial Replacement for Cement and PVC Granules for Fine Aggregates
摘要
India’s cement industry is at a crucial juncture, poised for substantial growth while concurrently facing pressing environmental challenges. The amalgamation of industrial by-products into concrete designs emerges as a fascinating avenue for sustainable practices. This practice not only alleviates the burden of disposal of industrial waste, but also brings about tangible enhancements to the mechanical properties of concrete. By enhancing its durability, strength, and resistance to severe environments, this approach emphasizes the likely for sustainable waste management while reinforcing the structural integrity of concrete infrastructure, thus contributing to the circular economy. GGBS and PVC granules offer potential solutions as they are industrial by-products or recycled materials, thereby decreasing dependence on original resources and mitigating ecological impact. Our research presents a green concrete M25 grade improved by utilizing GGBS as a partial replacement for cement that has shown improved concrete properties such as durability, strength, and improved chemical resistance. Similarly, using PVC granules as a substitute for fine aggregate has offered reduced density and improved workability, potentially leading to improved characteristics in concrete, thereby validating the efficacy of these materials in enhancing structural integrity and performance and paving the way for greener concrete. Increasing the PVC ratio by 30% shows a noticeable decrease in concrete compressive strength compared to a 20% replacement. Interestingly, for higher replacements of PVC granules, the split tensile strength increases.
