摘要
为提高海水环境中钢筋混凝土的使用寿命,从低砂率、低坍落度、低水泥用量方面优化混凝土配合比设计,采用改性木钙、引气剂复合使用和不同养护条件等三方面对改善低水灰比大掺量磨细矿粉大体积混凝土体积稳定性问题进行了探讨。
The mixing ratio design of concrete is optimized from the fields of low sand-ratio, low slump and low dosage of cement. Adopting such three fields as modified ligneous calcium, the compound use of leading gas agent and various maintainable conditions, the problem of improving the cubic stability of low cement-water ratio concrete with a large additive amount of grinding fine ore is discussed.
