三掺法配制高抛免振捣混凝土在清水混凝土立柱中的研究

Three blending method had high thrown of non-vibrating concrete research in concrete column

采用三掺法的设计思路,阐述了三掺法的技术优势,通过正交试验研究配制出高抛免振捣清水混凝土,以此解决立柱施工对混凝土性能的要求,并设计出混凝土浇筑施工工艺,解决高抛施工清水混凝土的施工难题。

Three mixing method is used to design train of thought.It expounds the technical advantages of three blending method, through orthogonal experimental study makes a cast high ofnon-vibrating concrete, in order to solve the performance of concrete pillar con- struction requirements, and designs the concrete pouring construction technology, solve cast high construction of as-cast concrete construction problem.
