透水混凝土在奥运羽毛球场馆室外铺装工程中的应用

透水混凝土具有极好的透水、透气性,水泥用量、粗集料种类和级配以及外加剂等均是影响混凝土透水性和强度的主要日素.通过改变水泥用量,采用不同种类的粗集料,加入适量外加剂,对搅拌工艺进行合理的控制,解决了透水混凝土在搅拌站生产困难的问题,并在北京工业大学奥运羽毛球馆广场工程中得以应用.

Pervious concrete for the project of Olympic Badminton Stadium of Beijing University of Technology

The pervious concrete features for excellent water permeability and air permeability.The amount of cement,variety and gradation of coarse aggregate and additive can deeply aflect water permeability and strength of the pervious concrete.The experiment solved the problem that it was difficult to produce the pervious concrete in mixing station through changing the amount of cement,using different kinds of coarse aggregate,mixing the appropriate amount of additive and controlling the mixing process properly.Fin...
