Composite-layer pavement brick and preparation method thereof
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.
本申请涉及路面砖技术领域，提供的复合层路面砖的制备方法，该制备方法在模具内表面先制备助剂层，再依次制备面层、连接层和底层；其中，形成助剂层，推迟接触模具面的混凝土的水化反应，延长接触模具面的混凝土的凝结时间，从而使与模具面接触的混凝土在后续冲刷处理中冲洗掉表面的水泥浆，得到具有粗糙表面的复合层路面砖，进而提供复合层路面砖的表面耐磨性，同时利用含有碎石的连接层连接面层与底层，能够增加面层与底层的界面结合力，提高复合层路面砖的承载力；该制备方法简单，能提高面层与地层的结合程度，保证面层和底层材料之间不易脱落，同时，降低材料的收缩性，使复合层路面砖材料承载力高，防滑性能好，耐久性能好，适合广泛应用。
