TK聚合物砂浆修补最早在20世纪80年代末应用于河北省岳城水库溢流坝面的修补中,在20世纪90年代中后期开始较多应用。它是一种新型的混凝土表面修补加固材料,具有粘结强度高、干缩变形小、抗压模量低,抗氯离子和硫酸盐离子侵蚀能力强的特点,而且可显著提高护筋阻锈能力,还具有一定的补偿收缩性能,同时价格比同类产品低。 As early as the late 1980s, TK polymer mortar repair was applied to repairing the overflow dam surface of Yuecheng Reservoir in Hebei Province. It was applied more and more in the mid and late 1990s. It is a new type of concrete surface repair and reinforcement material, which has the characteristics of high bond strength, small shrinkage deformation, low compressive modulus, strong resistance to chloride ions and sulfate ions, and can significantly improve the rust resistance Ability, but also has some compensation shrinkage, while the price is lower than similar products.
