优化C60高强度泵送混凝土的配合比设计

Optimized Design of Mixture Ratio of C60 High Strength Pump Concrete

本文在确定C60高强泵送混凝土的设计要求后,充分利用宁波地方特色的建筑材料,引入了多指标等水平的正交设计方法,通过重复性试验对混凝土的塌落度、收缩率、强度塌落度损失等指标进行验证,达到预期的要求。

The paper introduces the orthogonal design method by using the building materials typical of Ningbo and determining the design requirements of C60 high strength pump concrete, whose effect is proved through repeated experiments on the slump, the shrinkage and the intensity slump loss, etc. of the concrete.
