Chlorine salt influence on durability and strength of additive-free EPS lightweight concrete

This study explores the formulation of lightweight concrete (LWC) by incorporating expanded polystyrene (EPS) pearls as a partial replacement for coarse aggregate without supplementary bonding agents. The investigation focuses on assessing the resilience of the concrete in a sodium chloride environment, achieved by subjecting the material to immersion in two distinct salty water concentrations. Key parameters under scrutiny include EPS content, concrete strength, and salt concentration. Eight concrete groups were established, varying the replacement of natural coarse aggregate with EPS at volumes ranging from 0 to 70
