即使配合比设计（水泥含量，W/C比）对混合水泥混凝土的耐久性有影响，养护条件，特别是养护时间，也会影响混凝土抗碳化的耐久性。养护时间的选择取决于水泥含量，必须根据混凝土设计（28天强度，水灰比）进行调整。水泥含量低（或水灰比高）的混凝土必须比水泥含量高的混凝土养护更长时间。最后，一些相关性表明，在养护结束时的强度，它考虑了配合比设计和养护条件，能够评估混凝土抗碳化的耐久性。
Even if mix design (cement content, W/C ratio) has an effect on durability of concrete mixed with blended cement, curing conditions, particularly curing time, also affect concrete durability against carbonation. The choice of curing time depends on cement content, and must be adjusted to concrete design (28 day strength, W/C ratio). Concretes with a low cement content (or a high W/C ratio) must be cured longer than those having higher cement content. Finally, some correlations show that strength at the end of curing, which takes into account both mix design and curing conditions, is able to assess durability of concrete against carbonation.
