Roller compacted concrete interlayer surface treatment method
The invention provides a roller compacted concrete interlayer joint surface treatment method, which comprises the following steps: firstly, roller compacting concrete after concrete pouring, bulldozing the compacted concrete by using a leveling machine, and preparing cement paste from water, cement, a water reducing agent, a retarder and water according to a weight ratio of (630-680): (900-1050): 1.2: 0.1; after the roller compacted concrete starts to enter the warehouse, cement paste starts to be spread, and the cement paste is directly spread on the surface of the warehouse surface through a conveying hose; after the neat cement paste is spread, the roller compacted concrete is poured on the bin surface on which the neat cement paste is spread; within 16 hours after roller compacted concrete is finally set, treatment is not needed, during 16-32 hours, bristles are brushed on the interlayer joint surfaces, cement paste is laid and sprayed, and during 32-48 hours, bristles are flushed on the interlayer joint surfaces, and cement paste is laid and sprayed. The construction method has the beneficial effects that the construction method is simple and convenient to operate, the construction quality is improved, the continuous lift of roller compacted concrete construction is ensured, and the cement paste has better fluidity and higher permeability.
本发明提出了一种碾压混凝土层间结合面处理方法，首先，在混凝土浇筑后碾压混凝土，碾压后的混凝土用平仓机推平，将水、水泥、减水剂、缓凝剂、水按照（630~680）:（900~1050）:1.2:0.1的重量比配置水泥净浆；碾压混凝土开始入仓后既开始铺洒水泥净浆，水泥净浆铺洒使用输送软管直接铺洒在仓面表面；水泥净浆铺洒完毕后，碾压混凝土倾倒在铺洒水泥净浆的仓面上；在碾压混凝土终凝后16小时以内，无需处理、在16到32小时之间采时对层间结合面刷毛并铺洒水泥净浆、在32到48小时之间采用对层间结合面冲毛并铺洒水泥净浆。其有益效果是：本发明施工方法简单、便于操作，提高施工质量，保证碾压混凝土施工可连续升程，水泥净浆具有流动性更好、渗透性更强。
