Concrete anti-carbonization surface protective agent
The invention relates to a concrete anti-carbonization surface protective agent, and belongs to the technical field of building structure protection. The protective agent is composed of a component A protective pre-coating liquid and a component B inorganic protective agent, wherein the component A is composed of calcium hydroxide, magnesium hydroxide and water according to the mass ratio of (7-9): (1-3): (80-90); the component B is composed of sodium silicate, lithium silicate, a dispersing agent polyethylene glycol, a silicate stabilizer and water according to the mass ratio of (20-30): (20-30): (0.3-0.8): (0.1-0.5): (40-50); the protective agent realizes dual protection through capillary crystallization and increase of surface alkalinity, enhances the concrete anti-carbonization effect of the protective agent, can permeate into the surface layer of a building by 15-25 mm, fills pores in the surface of concrete, plays a role in densifying the surface layer and prevents harmful gas from entering, and is high in durability and environmentally friendly.
本发明涉及一种混凝土抗碳化表面防护剂，属于建筑结构防护技术领域。所述防护剂由A组分防护预涂液和B组分无机防护剂组成；其中A组分防护预涂液由氢氧化钙、氢氧化镁和水按照质量比(7～9)：(1～3)：(80～90)组成；B组分无机防护剂由硅酸钠、硅酸锂、分散剂聚乙二醇、硅酸盐稳定剂和水按照质量比(20～30)：(20～30)：(0.3～0.8)：(0.1～0.5)：(40～50)组成；所述防护剂通过渗透结晶作用和增加表面碱度，实现双重防护，增强防护剂的混凝土抗碳化效果，能够渗透进建筑物表层15～25mm，填充混凝土表面的孔隙，起到表层致密化作用，防止有害气体进入，耐久性强，绿色环保。
