Concrete carbonization inhibitor, preparation method and application
The invention discloses a concrete carbonization inhibitor, a preparation method and application, and belongs to the technical field of building materials. The concrete carbonization inhibitor is prepared from the following raw materials: modified calcium oxide, alkylol amine, an organosilicon waterproofing agent, a polycarboxylic acid water reducing agent, a filler and a defoaming agent, wherein the modified calcium oxide is calcium oxide subjected to siloxane surface hydrophobic modification. According to the concrete carbonization inhibitor, concrete is compacted through the filling agent and the modified calcium oxide reaction product, the amount of permeating carbon dioxide is reduced, water transmitted into the concrete is reduced by doping the waterproof agent, and meanwhile carbon dioxide permeating into the concrete is consumed through chemical reaction. According to the concrete carbonization inhibitor, through the dense hydrophobic and chemical combination effect, the effect of improving the carbonization resistance of concrete is achieved; the admixture can improve the carbonization resistance and long-term stability of concrete and effectively reduce the carbonization depth of the concrete.
本发明公开了一种混凝土碳化抑制剂、制备方法及应用，属于建筑材料技术领域。所述混凝土碳化抑制剂制备原料包括如下组分：改性氧化钙、醇胺、有机硅防水剂、聚羧酸减水剂、填充料、消泡剂，所述改性氧化钙为经过硅氧烷表面疏水改性的氧化钙。本发明混凝土碳化抑制剂通过填充剂以及改性氧化钙反应产物密实混凝土减少渗透二氧化碳的量，掺入防水剂减少水分传输到混凝土内部，同时通过化学反应消耗渗透到混凝土内部的二氧化碳。本发明混凝土碳化抑制剂通过上述密实疏水和化学结合作用，实现提升混凝土抗碳化性能的作用；所述外加剂能实现提升混凝土抗碳化性能与长期稳定性，有效降低混凝土的碳化深度。
