C50 钢纤维泵送混凝土配合比试验研究及工程应用

以泸州市沱江四桥及连接线工程跨江大桥C50钢纤维泵送混凝土配合比设计为例,采用泸州地区当地生产的原材料配制C50钢纤维泵送混凝土,介绍了C50钢纤维泵送混凝土的配合比设计试验过程,并对该混凝土施工性能和力学性能进行了试验研究,确定了符合设计和施工要求的混凝土配合比。

Experimental study and engineering application of C50 steel fiber pump concrete mixture ratio

Taking the fourth bridge of Tuojiang River in Luzhou City and the C50 steel fiber pump concrete mix proportion design of the connection project cross river bridge as an example, the C50 steel fiber pump concrete that produced by the local raw materials in Luzhou City was used, the mix proportion design process of the C50 steel fiber pump concrete was introduced, the concrete construction property and mechanical property were tested and studied, and the concrete mix proportion that accords with the design and construction requirements was determined.
