Structure and method for improving bonding performance of concrete repairing interface through carbonization
The invention discloses a structure and method for improving the bonding performance of a concrete repair interface through carbonization, and the structure comprises a to-be-repaired concrete matrix, a carbon-sequestration-carrier-containing cement-based repair material layer and a common cement-based repair material layer, the carbon sequestration carrier-containing cement-based repair material layer is positioned between the to-be-repaired concrete matrix and the ordinary cement-based repair material layer; a carbon-containing carrier in the cement-based repair material containing the carbon sequestration carrier is a porous carbon-loaded aggregate encapsulated with carbon dioxide, an encapsulation film is dissolved in water or an alkaline environment, and the pressure intensity of the encapsulated carbon dioxide is 0.2-5 MPa. The repairing material layer of the to-be-repaired surface contains a carbon sequestration carrier, so that carbon dioxide can be conveniently released to an interface transition area. The carbon dioxide waste is consumed; meanwhile, the interface adhesion is improved and repaired. The carbon dioxide reacts with the calcium hydroxide enriched on the repairing interface to generate calcium carbonate, the calcium hydroxide enriched on the interface is consumed in the process, the preferred orientation of calcium hydroxide enrichment is avoided, and the compact effect of the interface is achieved. And the bonding performance of the repaired interface is improved.
本发明公开了一种碳化提升混凝土修复界面粘结性能的结构及方法，包括待修复混凝土基体、含固碳载体水泥基修复材料层和普通水泥基修复材料层，其中，含固碳载体水泥基修复材料层位于待修复混凝土基体与普通水泥基修复材料层之间；所述含固碳载体水泥基修复材料中的含碳载体为封装有二氧化碳的多孔载碳骨料，封装膜遇水或碱性环境溶解，封装的二氧化碳的压强为0.2‑5MPa。待修复表面的修复材料层含有固碳载体，方便释放二氧化碳到达界面过渡区。消耗二氧化碳废弃物的同时提升修复界面粘结。二氧化碳与修复界面富集的氢氧化钙反应，生成碳酸钙，该过程消耗界面富集的氢氧化钙，避免氢氧化钙富集择优取向，界面实现致密效果。实现修复界面粘结性能的提升。
