نبذة مختصرة : Limestone Calcined Clay Cement (LC3) Technology is a low carbon cement that combines limestone, calcined clay, and clinker, aiming to reduce CO2 emissions by 40%-50% during production. In this study, large-scale investigations were conducted to explore LC3 as a potential substitute for conventional cement (CC). Mechanical and durability tests were performed on LC3, comparing results with CC and Pozzolana Cement (PC) concretes. The findings revealed that LC3 concrete exhibited promising early-stage strength similar to CC concrete. However, at 90 days, LC3 showcased a 10% higher strength compared to CC concrete. Additionally, LC3 displayed a remarkable 45% increase in resistance to moisture ingress, indicating improved durability over CC concrete. These results highlight the efficacy of low carbon cement in developing ternary blended cements that offer early strength and enhanced durability, making it a viable eco-friendly alternative in the construction industry. ; La tecnología de cemento de arcilla calcinada con piedra caliza (LC3) es un cemento con bajo contenido de carbono que combina piedra caliza, arcilla calcinada y clínker, con el objetivo de reducir las emisiones de CO2 en un 40 %-50 % durante la producción. En este estudio, se realizaron investigaciones a gran escala para explorar LC3 como un posible sustituto del cemento convencional (CC). Se realizaron pruebas mecánicas y de durabilidad al LC3, comparando resultados con los hormigones CC y Cemento con Puzolanas (PC). Los hallazgos revelaron que el hormigón LC3 exhibió una prometedora resistencia en la etapa inicial similar al hormigón CC. Sin embargo, a los 90 días, LC3 mostró una resistencia un 10 % mayor en comparación con el hormigón CC. Además, LC3 mostró un aumento notable del 45 % en la resistencia a la penetración de agua, lo que indica una mayor durabilidad que el hormigón CC. Estos resultados destacan la eficacia del cemento con bajo contenido de carbono en el desarrollo de cementos mixtos ternarios que ofrecen una resistencia temprana y una ...
