Abstract

The invention relates to the technical field of pavement bricks, and provides a preparation method of a composite layer pavement brick, which comprises the following steps: preparing an assistant layer on the inner surface of a mold, and sequentially preparing a surface layer, a connecting layer and a bottom layer; wherein an auxiliary agent layer is formed, a hydration reaction of the concrete incontact with the mold surface is delayed, and the setting time of the concrete in contact with the mold surface is prolonged, so that cement paste on the surface of the concrete in contact with the mold surface is flushed away in the subsequent flushing treatment, and the composite-layer pavement brick with the rough surface is obtained. then the surface abrasion resistance of the composite-layerpavement brick is provided, meanwhile, the surface layer and the bottom layer are connected through the connecting layer containing the gravels, the interface bonding force of the surface layer and the bottom layer can be increased, and the bearing capacity of the composite-layer pavement brick is improved; the preparation method is simple, the combination degree of the surface layer and the stratum can be improved, it is guaranteed that the surface layer and the bottom layer are not prone to falling off, meanwhile, the contractility of the material is reduced, and the composite-layer pavement brick material is high in bearing capacity, good in anti-skid performance, good in durability and suitable for wide application.

Description

technical field [0001] The application belongs to the technical field of pavement bricks, and in particular relates to a composite layer pavement brick and a preparation method thereof. Background technique [0002] Pavement bricks are a common type of brick in my country, also known as pavement bricks, which are usually widely used in sidewalks, residential areas, and squares. It is made of cement, gravel, and sand as raw materials. It is shaped by vibration, and the surface is cut into stripes or squares. It looks like granite. Some are elegant and rough, and some are romantic and soft. [0003] The production of concrete pavement bricks also has a certain history. The early concrete pavement bricks were relatively thin, and their strength, wear resistance and flexural resistance were relatively low, so their service life was short. The concrete pavement bricks used in some cities in our country are poured with plastic molds. Although this kind of pavement bricks are brig...
