新旧混凝土接续面上泛浆现象的基础特性研究

Basic characters study of bleeding generated on the jointing face of successive layers of concrete

阐述了在旧混凝土上沿铅直方向浇筑新混凝土时,在接续面上产生的泛浆将影响接续面边界生成物的生成过程,通过设置不同管径的圆筒容器来改变水泥浆的接续界面,由此来研究接续面边界的变化对泛浆特性的影响。

When jointing the new concrete on the old concrete in vertical direction, the bleeding generated on the jointing face of successive layers will affect the generating. In this paper various tests are preformed by installing some cylinder container of different pipe diameters to study the result of bleeding through changing of the jointing face of successive layers.
