摘要
针对高强轻集料混凝土泵送施工难的特点 ,采用粉煤灰和高效减水剂复掺技术配制出了混凝土抗压强度高达CL6 0 ,初始坍落度大于 2 0 cm、扩展度大于 5 0 cm,6 0 m in坍落度大于 18cm的轻集料混凝土 。
It is difficult to pump Light-weight Aggregate Concrete(LWAC), especially for the High-strength LWAC. Therefore, the problems of pumping LWAC are resolved successfully through mixing up fly-ash and superplasticizer. This technology is also applied to the Caidian Hanjiang river bridge project.
