配合比设计是确保混凝土耐久性最关键的环节之一，提出混凝土最大水胶比、最小胶凝材料用量限值，就是有效而可行的措施。掺加矿物掺和料已被证明是改善混凝土施工性能、提高混凝土耐久性能的重要技术措施。所以，高性能混凝土必须掺加矿物掺和料和化学外加剂。在以往按强度设计混凝土配合比的设计方法中，首先按强度等级计算水灰比，如今按耐久性要求设计混凝土配合比时，首先是根据环境类别和作用等级，确定混凝土的水胶比和各种胶凝材料用量。在条件许可的情况下，尽量选用较低的水胶比，减少单方用水量和胶凝材料用量，有利于提高混凝土的密实性，降低混凝土的渗透性并减少收缩量，对提高混凝土的耐久性非常有利。另外，降低水胶比是发挥矿物掺和料对混凝土强度贡献的重要条件。但过少的胶凝材料用量对混凝土的强度、耐久性和工作性能不利，因此胶凝材料用量应有最小限值。
