| dc.title | Mechanical performance and microstructure of binary cement under flow-through CO₂ curing | en_US |
| dcterms.abstract | In this study, 50% of the Portland cement (PC) was replaced with reactive MgO cement (MOC) and a flow-through CO₂ curing method at ambient pressure was adopted to cure the MOC-PC binary pastes. Different CO₂ curing regimes influences on the carbonation degree and compressive strength of the binary cement were studied, including CO₂ concentration, curing time and relative humidity. CO₂ uptake, the formation of carbonation products and compressive strength of blocks were investigated. Results revealed that (1) OPC-MOC binary cement showed a weaker compressive strength compared to OPC samples. (2) CO₂ curing significantly improved the compressive strength of the OPC-MOC binary cement. (3) 50% relative humidity was the most appropriate for the carbonation of OPC-MOC binary cement. (3) Either increased in CO₂ concentration or curing duration enhances the carbonation and mechanical properties of the samples. | en_US |
