摘要：
PROBLEM TO BE SOLVED: To provide a surface modifying agent which has high permeation property to mortar or concrete using alumina cement and improves the strength of the fragile surface layer formed by dry out or the like, and further which reduces dry shrinkage and neutralization and improves acid resistance, and to provide a surface modification method using the same.
SOLUTION: The surface modifying agent, obtained by mixing lithium nitrite and a resin, is applied onto the surface of concrete. Thereby, the lithium nitrite is ionized, deeply permeates into the concrete, and accelerates a reaction. The resin remains at the surface and forms a film so as to prevent the evaporation of water from the inside and to enhance the permeation property and the reactivity. Accordingly, the concrete is protected.

要解决的问题：提供一种表面改性剂，其使用氧化铝水泥具有对砂浆或混凝土的高渗透性，并且提高由干燥等形成的脆性表面层的强度，并进一步降低干缩率， 中和并提高耐酸性，并提供使用其的表面改性方法。 解决方案：将混合亚硝酸锂和树脂获得的表面改性剂施加到混凝土表面上。 因此，亚硝酸锂离子化，深入渗透到混凝土中，并加速反应。 树脂保留在表面并形成膜，以防止水从内部蒸发并增强渗透性能和反应性。 因此，混凝土受到保护。 版权所有（C）2009，JPO＆INPIT
