Technology for improving wear resistance and durability of concrete by controlling thickness of laitance of concrete
The invention discloses a technology for improving wear resistance and durability of concrete by controlling the thickness of concrete laitance, which comprises the following steps: S1, binding a pouring reinforcing mesh on a construction surface, pouring first concrete grout on the pouring reinforcing mesh, paving and vibrating to obtain base layer concrete; and S2, before initial setting of the common concrete formed in the step S1, a surface wear-resistant material is poured. The mortar layer and the laitance layer formed through layered paving and pouring are thinner, the formed wear-resistant layer is tightly combined and solidified with the foundation concrete and the reinforcing mesh, the connection strength between layered structures can be high, the wear-resistant durability of the wear-resistant layer is greatly improved, the maintenance period is prolonged, and the service life of the wear-resistant layer is prolonged. The problem that the strength of the anti-impact and wear-resistant concrete is difficult to control and control cracking at high temperature is solved, the use amount of the wear-resistant concrete is reduced by 50-80% due to the layering position, the manufacturing cost of the wear-resistant concrete is reduced, and the use amount of raw materials is reduced.
本发明公开了一种通过控制混凝土浮浆厚度提高混凝土耐磨耐久性技术，包括以下步骤：S1、在施工面绑扎浇筑钢筋网，在浇筑钢筋网上浇筑第一混凝土浆，摊铺振捣，得到基层混凝土；S2、在步骤S1形成的普通混凝土初凝前，浇筑表面耐磨材料。通过如此分层摊铺浇筑形成的砂浆层和浮浆层更薄，且形成的耐磨层与基础混凝土以及钢筋网紧密结合凝固，可以使形成分层结构之间连接强度高，通过使用耐磨材料的骨料，大幅度提高耐磨层的耐磨耐久性，延长维修周期，并解决了抗冲耐磨混凝土强度高温控防裂难度大的难题，分层位置使耐磨混凝土的使用量减少50％～80％，降低了耐磨混凝土的造价，减少了原材料的用量。
