摘要
从水工混凝土的配合比设计视角,对比分析了水工混凝土和建工混凝土的胶凝材料用量、掺合料和机制砂石料的品质要求、骨料的基准含水状态、强度等级的设计龄期、配合比的设计原则等,指出建工混凝土宜加大掺合料应用、积极使用机制砂石料、在设计混凝土配合比时逐步使用以饱和面干状态作为砂石料的基准含水状态、延长强度等级的设计龄期和贯彻实施强度与耐久性并重的混凝土配合比设计原则。
The amount of binding materials, quality requirements on mineral admixtures and artificial aggregates, benchmark moisture status of aggregates, design age of strength grade, design philosophy of mix proportion of hydraulic concrete and concrete for building projects were compared and analyzed from the view of mix design of hydraulic concrete and points out that the concrete for building projects should better increasing application of mineral admixtures, using artificial aggregates positively and gradually taking the mois- ture - laden and surface - dry condition as the benchmark moisture status of aggregates when designing the concrete mix proportion, ex- tending the design age of strength grade and implementing the design principle of concrete mix proportion of that regard the strength and the durability as equally important factor.
