核废料储存库需要高度耐用的胶凝材料，才能在抵抗淋溶和降解的情况下运行数千年以上。通过降低渗透率和将水泥水化产物转变为较难溶解的基质，可以有效地提高胶凝材料的耐久性。本文介绍了以富贝利特水泥和γ-2CaO·SiO_2为主要组份的碳化新型胶凝材料的性能。此外，利用预测淋溶模型考察了该水泥的长期淋溶性能，并与普通硅酸盐水泥进行了比较。
Nuclear waste repositories need highly durable cementitious materials to function for over thousands of years while resisting leaching and degradation. The durability of cementitious material can be effectively improved by reducing permeability and by changing cement hydrates to a less soluble matrix. This paper describes the properties of carbonated new cementitious materials containing belite-rich cement and γ-2CaO·SiO2as main components. In addition, the long-term leaching properties are investigated and compared with ordinary Portland cement by using a predictive leaching model.
