大粒径高流态泵送混凝土的研究与应用

Research on the bulkily granular and high flowing pump concrete and its application

根据大粒径高流态泵送混凝土施工的要求,研制出了符合管道下料的大粒径高流态泵送混凝土,并对其发展进行了介绍,结合工程实例,阐述了它在建井工程中的应用和不同强度等级的配合比设计,并对试验结果进行了分析,以推广该混凝土的应用。

According to construction specifications on the bulkily granular and high flowing pump concrete corresponding pump concrete is prepared, which meets the requirements on the construction of pipes. Combined with practical work the application of the bulkily granular and high flowing pump concrete in shaft engineering as well as mix proportion design of concretes with different strength levels are elaborated. Analysis is also made, in order to promote the application of this kind of concrete.
