Abstract

The application of the present invention discloses a preparation method and product of an inorganic binder sand-based permeable brick, which belongs to the field of building materials. The fluidity is more balanced and the contact area with cement is increased to improve the pore uniformity of the surface layer and the bonding strength between adjacent sand particles. In addition, the addition times and the number of water, cement, surface sand and primer in the fabric and base material are changed. The timing of adding changes the bonding force and pore structure between cement and surface sand, cement and base material, and increases the contact area between cement and water through two "water-cement" adding methods, so that the cement can be more fully hydrated and improve its own Coagulation strength. The method of the invention solves the problem that the strength, wear resistance and water permeability of the existing sand-based permeable bricks cannot be balanced, and also solves the problem of using an organic binder to improve the strength, wear resistance and water permeability of the existing sand-based permeable bricks The rate reduces the problem of weather resistance and service life.

Description

technical field [0001] The invention belongs to the field of building materials, and more specifically relates to a preparation method and product of an inorganic binder sand-based permeable brick with high performance and simple composition. Background technique [0002] With the continuous advancement of urbanization, the number and scale of cities have grown rapidly. In the planning and design of urban construction, in order to improve the appearance of the city and improve the passability of the road surface, the road surface is usually covered with impermeable concrete layers, asphalt or concrete bricks. These hardened road surfaces block the heat of the urban surface and the atmosphere In exchange with water, it is also difficult for rainwater to penetrate into the underground soil, causing serious water shortage in the surface soil, resulting in a significant increase in the cost of urban landscaping, and at the same time increasing the risk of urban waterlogging and ...
