Sponge urban construction has become one of the heated topics in the fields of science and technology, and faces many disputes. There are different opinions and cognitions to the connotations, objectives, contents and effects of sponge urban construction. But investigating its foundation of sponge city is the basis of the permeable brick. The purpose of this test is to find the optimum mix ratio of permeable bricks, that is, to make them have good permeability on the premise of satisfying certain strength. Through experiments, aggregate cement ratio is fixed; water cement ratio and gluing ratio are adjusted. The conclusion is that the best mixing ratio is aggregate cement ratio 3.5, water cement ratio 0.38 and gluing ratio 2%, which is to meet the requirements of the sponge city for the compressive strength and permeability coefficient of single brick.
