Abstract
The invention disclosed a composite permeable brick comprising a permeable surface layer and a permeable base layer. The surface layer and the permeable base layer, which respectively comprise an aggregate and a binder adhering to the aggregate, are closely combined together. The binder in the permeable surface layer at least comprises a hydrophilic binder. The permeable brick according to the invention has a good permeability and is of low cost, because of the compact and permeable surface of the brick. The invention also discloses a mixture for preparing the composite permeable brick, comprising an aggregate and a binder adhering to the aggregate. The binder at least comprises a hydrophilic binder, and the binder/aggregate ratio is from 1:100 to 20:100 by mass. The composite permeable brick and the mixture of the invention may be used for road surfacing, water circulation, water filtration and water purification, promoting the full utilization of rainwater resources and improving the urban water circulation.
