泵送高强轻集料混凝土的研究
Study on the Pumping High-strength Light-weight Aggregate Concrete
【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 ,并成功应用于桥面铺装工程
【Abstract】 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.
