The study aims to understand the performance and durability of a sodium carbonate alkali-activated slag (AAS) based on a performance-approach. Equivalent performances were obtained between the AAS and CEM III/C-based concretes having a water/binder ratio of 0.4 regarding compressive strength, porosity, resistance to nitric acid, and sodium sulfate. AAS exhibited higher resistivity and better resistance to chloride, assessed by a chloride migration test. The AAS showed similar carbonation resistance to CEM III/C and CEM III/B concretes with w/b ratios of 0.47 and 0.53, respectively. A discussion of durability tests for their application to this type of binder is conducted.

基于性能的方法评估碳酸钠碱激活矿渣混凝土的耐久性

该研究旨在基于性能方法了解碳酸钠碱激活渣（AAS）的性能和耐久性。水/粘合剂比为 0.4 的 AAS 和 CEM III/C 混凝土在抗压强度、孔隙率、耐硝酸和硫酸钠方面获得了相同的性能。通过氯化物迁移测试评估，AAS 表现出更高的电阻率和更好的耐氯化物性。 AAS 表现出与 CEM III/C 和 CEM III/B 混凝土相似的抗碳化性能，水灰比分别为 0.47 和 0.53。对此类粘合剂的耐久性测试进行了讨论。
