| description | To enhance the carbon sequestration of concrete and the mechanical properties of polyurethane foam concrete (PFC), a novel formulation was developed using ordinary Portland cement, basalt stone powder, diphenylmethane diisocyanate, and polyether polyol. This study investigated the optimized production of PFC and its CO2 capture efficiency. The optimal polyurethane crosslinking was achieved with a specific diphenylmethane diisocyanate (MDI) to polyether polyol (PP) ratio, resulting in PFC with ideal densities for structural applications. Comprehensive testing after a curing period of 48 hours yielded a maximum compressive strength of 9.16 MPa and an improved flexural strength of 4.3 MPa, demonstrating the formulation's effectiveness. Thermogravimetric analysis highlighted the CO2 absorption capacities of PFC at various densities. Furthermore, an accelerated carbonization study revealed significant depth increases within the initial 8 hours. Microstructural analysis confirmed that lower-density PFC samples exhibited enhanced carbonization, with notable increases in CaCO3 content, suggesting improved carbon sequestration potential. These findings indicate that the tailored PFC formulation not only strengthens material properties but also contributes to environmental sustainability by effectively capturing CO2. |
