Super-permeable concrete surface reinforcing agent as well as preparation method and application thereof
The invention relates to a super-permeable concrete surface reinforcing agent as well as a preparation method and application thereof. The super-permeable concrete surface reinforcing agent is prepared from the following raw materials: a dispersing agent, fluosilicate, nano oxide, an early strength agent and water. The super-permeable concrete surface reinforcing agent is good in permeation effect, the chemical reaction generated when the super-permeable concrete surface reinforcing agent permeates into the surface of concrete and the concrete is milder, and the action time is longer. The concrete surface reinforcing agent is a multi-component chemical reagent, is small in viscosity, is brushed or sprayed on the surface of concrete, can quickly permeate into the concrete and react with cement hydration by-products in the concrete to generate a large amount of gel, and the gel can block capillary micropores in the concrete, so that the concrete surface reinforcing agent can be used for reinforcing the concrete surface. Therefore, the surface performance of the concrete, such as compactness, compressive strength, hardness, wear resistance, air tightness, impermeability and carbonization resistance, is improved.
本发明涉及一种超渗透型混凝土表面增强剂及其制备方法和应用。所述超渗透型混凝土表面增强剂的制备原料包括分散剂、氟硅酸盐、纳米氧化物、早强剂和水。本发明所述超渗透型混凝土表面增强剂不仅渗透效果好，而且渗透到混凝土表面和混凝土产生的化学反应更加温和、作用时间更长。本发明所述混凝土表面增强剂是一种多成分化学试剂，粘度小，涂刷或喷涂在混凝土表面，能快速渗透至混凝土内部，与混凝土中水泥水化的副产物发生反应，生成大量的凝胶，这些凝胶能堵塞混凝土内部毛细微孔，从而增加混凝土的表面性能，如密实性、抗压强度、硬度、耐磨性，气密性、抗渗及抗碳化能力。
