Residue fluidized catalytic cracking in lightweight polystyrene concrete: A sustainable construction solution

Abstract

This study explores the potential of Polystyrene concrete, a globally recognized lightweight concrete, in the context of Vietnam's construction industry. The research incorporates non-hazardous industrial waste, specifically Residue Fluidized Catalytic Cracking (RFCC), as a novel additive in the production of lightweight concrete. The systematic approach involves evaluating different cement types and gradually replacing cement with RFCC to identify an optimal formula for lightweight Polystyrene concrete. The study aligns with global sustainability goals and addresses local gaps by contributing practical insights and solutions to challenges in traditional brick production. The experimental setup utilizes Expanded Polystyrene (EPS) granules, standard cement types (PCB50, PCB40, and PCB30), and super foaming additives. Results indicate the feasibility of replacing up to 10% of cement with RFCC, offering a promising avenue for effective industrial waste management. This research aligns with the Sustainable Development Goals (SDGs) and contributes to a more environmentally conscious scientific community.
