石板坡长江大桥复线桥工程专用水泥对混凝土性能影响研究

Research on Effects of Shi-banpo Multiple Track Bridge Special-Purpose Cement on Properties of Concrete

针对石板坡长江大桥复线桥结构和施工特点生产的专用水泥通过对水泥矿物组成及水化热的控制,对降低混凝土温升,提高混凝土体积稳定性和耐久性起到了直接、有效的作用。采用专用水泥配制的高性能混凝土具有良好的综合技术性能。

Special-purpose cement is produced to fit for the structural and constructive characteristics of Shi-banpo Yangtze multiple track bridge. Through controlling mineral consistence and hydration heat of the special purpose cement, it can reduce the temperature rising, improve the volume stability and durability of concrete directly and effectively. By using the special-purpose cement, HPC possesses good synthetic technical performance.
