泵送钢纤维混凝土在桥梁工程的配制及应用情况

Processing and application of steel fiber concrete carried by pump at bridg construction

从湖南省益阳市南县茅草街大桥的工程实际出发,着重论述怎样通过理论指导和试配实践来确定主桥桥面现浇层CF40泵送钢纤维混凝土的原材料和配合比,以及怎样进行现场泵送时的质量控制。

Strafing from the engineering of Maocaojie Bridge at Yiyang Nan county in Hunan province,the paper is devoted to discuss how to determine the level of raw material and mixture-ratio of CF40 with in the guidance of theory and experimentation, which is applied in main bridge deck of cast-in-place. Also it is presented that how to control the quality of concrete at pumping locale.
