混凝土界面剂是一种聚合物改性水泥浆沙，它可以加强与基层的粘合力，使物体更加牢固，它还有例如耐热，防水，抗冻融性能强等特点。在日常生活中，我们的墙壁是不允许出现抹灰层空鼓，起壳的现象，而混凝土界面则能够很好的避免这些缺陷。它主要用于混凝土基层抹灰界面处理和大型砖块的表面处理。
Concrete interfacial agent is a kind of polymer modified cement slurry sand, which can strengthen the adhesion with the base and make the object more firm. It also has such characteristics as heat resistance, waterproof, freeze-thaw resistance and so on. In our daily life, our walls are not allowed to appear the phenomenon of plastering layer empty drum, shell, and the concrete interface can well avoid these defects. It is mainly used for plastering interface treatment of concrete base and surface treatment of large bricks.
