This study aimed to assess the mechanical and durability properties of high-strength limestone calcined clay cement (LC3) concrete and its comparison with high-strength concrete (HSC) using waste glass powder (GP). The novelty of this research is the addition of waste glass powder as an alternative to silica fume in HSC mixes with 0%, 5%, 10% and 15% replacement by weight of ordinary Portland cement (OPC) and LC3. The aim was to investigate the efficiency of this recycled material in providing eco-friendly concrete in order to reduce hazardous materials during conventional concrete production. The mechanical properties of both concrete types included compressive strength, flexural strength and split tensile strength, and the durability properties included resistance against carbonation, permeability and water absorption. The experimental results of the mechanical properties showed that LC3 concrete with 10% replacement of OPC with GP performed better than LC3 and OPC control. The use of 10% GP as partial replacement was found to be ideal in terms of compressive, flexural and split tensile strength. The compressive strength and split tensile test showed that strength increased with an increase in the carbonation exposure period for both concrete types, and after 12 months of carbonation exposure, LC3 concrete containing 10% of glass powder replacement exhibited the maximum compressive strength. The average water penetration depth of OPC and LC3 concretes decreased with an increase in glass powder replacement. OPC exhibited greater water absorption or less resistance to water penetration, whereas LC3 exhibited lower water absorption. The carbonation depth of LC3 concrete was observed to be less than that of OPC, as the penetration depth was lower than OPC.
