透水混凝土在奥林匹克森林公园的工程应用

Application of pervious concrete in the Beijing Olympic Forest Park

主要介绍透水混凝土的研制和应用过程。比较了粒径为10～20mm和5～10mm的碎石透水混凝土的性能差别,论证了水泥用量、水灰比对透水混凝土强度、透水系数和孔隙率的影响,达到了C25强度等级混凝土的较高强度,并且在奥林匹克公园得到了成功的应用。

It introduces research and application of pervious concrete,and compares concrete performance of the aggregate diameter for 10-20 nun with 5- 10 mm, and demonstrates the effect of a series factors （cement dosage, water-cement ratio） on concrete performance.The concrete strength reaches C25 grade, and it＇s high in pervious concrete.It is applied successfully in the Beijing Olympic Forest Park.
