透水混凝土制备工艺研究

Study on preparation technics of pervious concrete

针对透水混凝土的特点,对其制备技术进行了试验研究,试验得出,特殊的集料表面包裹搅拌法能保证集料被稠度适宜的胶结材均匀包裹,振动/压制复合成型使透水混凝土具有很好的密实度和透水性,标准养护或覆盖薄膜保湿养护有利于胶结材强度的正常顺利发展。

A series of preparation technics of pervious concrete are studied based upon its structure characteristic. It can be concluded by experiments that aggregate can be wrapped equably with binder in virtue of special mixing method,vibration associated with pressure can make pervious concrete to have good compactibility and permeability,and the binder strength can be developed normally and successfully by standard curing or keeping binder humidity curing with squeeze film.
