Based on the deterioration mechanism of corrosive medium, a lot of polymer such as ternary-polymer, adding-felt addition, hydrophobe and polypropylene fiber were added to enhance the performance of anti-corrosion, anti-penetration, conglutination and anti-cracking of original cementious material. The microstrure of cementious material was changed from the simplex hydration product of cement to the superposition structure of the hydrolysate of polymer and the hydration product of cement. A lot of the corrosive ions were prevented from the interior of concrete by this stable structure. The results of tryout indicated that the mending material has the good effect at the corrosion form of corrosive medium.

根据介质腐蚀形式的劣化机理，该文以提高修补材料耐腐蚀性能、抗渗透性能、粘结性能和抗裂性能为出发点，采用添加有机硅改性三元共聚物、增粘剂、孔隙憎水剂等多种聚合物和聚丙烯纤维对原水泥基材料进行改性，使得修补材料的内部微观结构从单纯的水泥水化产物转变成聚合物和水泥水化产物叠合的空间网状结构，这种稳定的结构能有效抵抗各种介质离子的侵蚀，在实际工程上的试用也显示出新修补材料良好的使用效果。
