摘要
结合苏通大桥承台的特点,阐述了大体积混凝土的配合比设计原则,从水化热角度进行了外加剂优选,同时进行了承台大掺量粉煤灰混凝土配制和系统的性能研究,并提出了苏通大桥超大体积承台施工用混凝土配合比。
According to the characteristics of platform in butong bridge preparation were introduced. The optimum additive was chosen by analyses of hydration heat. The preparation and performance of mass concrete with high volume fly-ash were studied, and then concrete mix ratio for the mass concrete of platform in Sutong bridge was proposed.
