dc.description.abstractThe study investigated the impact of Accelerated Carbonation Curing (ACC) on the performance of concrete containing OPC 43 and PPC cements. The evaluation encompassed both strength aspects, such as compressive strength, and permeability properties, including water absorption, chloride permeability, and sorptivity. The research also delved into the microstructure of OPC 43 and PPC cement concrete through SEM and XRD analyses. The curing methods encompassed water curing and carbonation curing for varying durations (3 to 24 hours), followed by subsequent water immersion until testing at 7, 28, and 56 days. Results revealed that while early carbonation fostered initial concrete strength, this effect waned in later stages. Carbonated samples exhibited reduced water absorption at 1, 3, and 28 days, alongside diminished sorptivity and enhanced resistance to chloride permeability. The optimal carbonation durations were identified as 15 and 12 hours for OPC 43 and PPC cements, respectively. Microstructural analysis showcased the replacement of calcium hydroxide (Ca(OH)2) with calcium carbonate (CaCO3) in carbonated concrete, contributing to its strength. Moreover, denser microstructures were observed at 12 and 18 hours of carbonation compared to traditional water curing methods.en_US
