Abstract

The invention provides anti-corrosion and anti-shrinkage pavement bricks and a preparation method thereof and relates to the technical field of production of pavement bricks. Each anti-corrosion and anti-shrinkage pavement brick comprises a surface layer, a first middle layer, a second middle layer and a bottom layer. The preparation method comprises the following steps: (1) preparing materials of the surface layer; (2) preparing materials of the first middle layer; (3) preparing materials of the second middle layer; (4) preparing materials of the bottom layer; (5) molding, de-molding, stacking and curing. By adopting the anti-corrosion anti-shrinkage pavement bricks, the problems of existing pavement bricks that the anti-corrosion property is poor, the anti-shrinkage property is poor, the compressive strength is low and wastes cannot be reutilized are solved.

Description

technical field [0001] The invention belongs to the technical field of pavement brick production, and in particular relates to a corrosion-resistant and shrinkage-resistant pavement brick and a preparation method thereof. Background technique [0002] As a paving material, pavement bricks have a wide range of applications and a huge daily consumption of raw materials. It is urgent to find other alternative materials to save the development and utilization of raw materials. [0003] Applying construction waste materials and industrial waste to pavement bricks not only solves the problem of excessive consumption of pavement brick materials, but also solves the problem that construction waste materials and industrial waste cannot be recycled and reused. [0004] In addition to the high demand for materials, pavement bricks also have high requirements for their own performance. However, the current pavement bricks have the problems of poor corrosion resistance, poor shrinkage r...
