泵送粉煤灰混凝土在地下工程中的应用

The Application of Pumping Flyash Concrete in Underground Works

根据粉煤灰的物理和化学特性及其对泵送混凝土技术参数的优化效应,结合工程实际应用,提出了对泵送粉煤灰混凝土原材料和配合比设计方法等方面的技术要求,给出了适应于地下工程的泵送粉煤灰混凝土的配合比,可供粉煤灰应用人员从事泵送混凝土施工时参考。

According to the physical and chemical characteristics of flyash,and its optimized effect of technical parameters for the pumping concrete, combined with practical application in the underground works, the technical requirements for raw material and mixture ratio of the pumping flyash concrete wrer proposed. The suitable mixture ratio adapted to pumping flyash concrete in the underground works was also put forward, This research can offer a reference for personnel who may engage in pumping concrete construction.
