Abstract

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.

一种低碳水泥(LC3)作为高强度混凝土中的可持续材料:绿色混凝土

石灰石煅烧粘土水泥(LC3)技术是一种低碳水泥，它将石灰石、煅烧粘土和熟料结合在一起，旨在将生产过程中的二氧化碳排放量减少40%-50%。在这项研究中，进行了大规模的调查，以探索LC3作为传统水泥(CC)的潜在替代品。对LC3进行了力学和耐久性试验，并与CC和PC混凝土进行了比较。结果表明，LC3混凝土具有与CC混凝土相似的早期强度。然而，在90天时，LC3的强度比CC混凝土高10%。此外，LC3的抗湿性显著提高了45%，表明其耐久性优于CC混凝土。这些结果突出了低碳水泥在开发三元混合水泥方面的功效，这种水泥提供了早期强度和增强的耐久性，使其成为建筑行业可行的环保替代品。
