Considerable environmental issues arise as concrete manufacturing involves extensive emission of carbon dioxide while the built structures suffer from cracking and chemical deterioration. The study aimed at enhancing the durability and mechanical properties of superabsorbent polymer concrete reinforced with nanozirconia (NZ/SAPC) by preparing the concrete through the incorporation of superabsorbent polymers (SAPs) and nanozirconia (NZ). The higher performing experimental mix with addition of 1 percent SAP and 1 percent NZ by the weight of cement exhibited compressive strength of 41 MPa at self-curing, 18% and 14% better flexural strength and split tensile strength and 30% less chloride penetration against corrosion. The statistically optimal blend which was determined as 0.542 percent NZ and 1 percent SAP, demonstrated a very similar performance and was confirmed by confirmatory tests. The combination of NZ and SAPs in concrete enhanced concrete strength by pore refinement and enabled internal curing. Through elongating the life of the infrastructures, NZ/SAPC formula solutions support carbon emission reductions. Implementing NZ/SAPC brings in new changes and enhancements in concrete used in construction, thus creating buildings that can adapt to climate change with self-curing capability.
