摘要
根据青藏铁路环境特点,分析了低温早强耐久防腐高性能混凝土的技术要求,重点对原材料选择和依据正交试验优化混凝土配合比等进行了介绍,依据本文方法设计的混凝土配合比完全满足施工及规范要求。
According to the environment features in Qinghai-Tibet railway line, the technique requirements for erosion resistant enduring concrete of early strength under low temperature are analyzed, and the selection of raw materials of concrete and concrete mix proportion design through orthogonal test are emphatically introduced. Concrete mix proportion from the method in this paper perfectly satisfies the requirements of construction and specification.
