Abstract

The invention discloses an inorganic permeable brick and a preparation process thereof. The inorganic permeable brick is provided with a water-permeable surface layer and a water-permeable bottom layer, and the water-permeable surface layer is made of fine aggregate, the first inorganic binder coated with fine aggregate and silicate and / or phosphate compound, the second inorganic adhesive binder, the water-permeable bottom layer uses coarse aggregate and the third inorganic binder covering the coarse aggregate, and the use of the first inorganic binder and silicate and / or phosphate compounds can increase the strength of the aggregate The smoothness of the surface makes the pores of the formed permeable surface layer uniform and smooth, not easy to be blocked, and prolongs the life of the permeable brick. At the same time, using the inorganic system composed of the first inorganic binder, the second inorganic binder and the third inorganic binder, the aging resistance and freeze-thaw resistance of the inorganic permeable bricks are improved.

Description

technical field [0001] The invention belongs to the technical field of water-permeable building materials, and in particular relates to an inorganic water-permeable brick and a preparation process thereof. Background technique [0002] Permeable bricks originated in the Netherlands. At first, the brick body of permeable bricks was not permeable. The gap of about 2mm reserved between bricks can allow rainwater to penetrate into the ground through the brick joints when it rains, replenishing water to prevent ground subsidence. Later, this permeable brick joint technology was improved into a permeable brick that achieves water permeable effect by absorbing water, permeating water, and conducting water through the brick body, and is widely used in urban road reconstruction. [0003] With the rise of the concept of sponge city in my country, and in order to alleviate the harm of urban waterlogging in summer, water seepage pavement and rainwater collection system have been paid at...
