Now some people unilaterally think that the bonding strength of putty of polymer mortar wall is faster, better, better, more elastic, better. In fact, this is not the case. After forming the strength of cement hydration, it is rigid and can not be flexible. The so-called elasticity is that it can not reach the normal cement strength and the sealing ability of high elastic material is strong. It can close or even completely seal porous cement, hinder cement hydration and prevent water. Self-maintenance (breathing) of mud under natural conditions is not conducive to the release of internal stress in cement.

　　Polymer mortar and putty of exterior wall have high bonding strength. As far as material performance is concerned, cement is an inorganic hydraulically cementing material. Its bonding strength is good. Even if: 4 compared with cement bricks and stones, the precondition is full hydration. Because cement hydration and setting hardening are a continuous process, the strength formation and stability of cement is a gradual and rather long process. After the first setting, the result of setting and hardening depends on the degree of hydration of cement and concrete by using self-maintenance ability, natural conditions, that is to say, as long as the cement hydration condition is good and the maintenance condition is good, the strength of cement may increase after 10 years, and ErSanTian will never achieve the ideal or 28-day strength. The strength of cement is realized on the water surface, but not on the water surface. It is adding glue to improve strength, which is the experience and lesson we should learn.

　　We believe that polymer cement mortar, main raw materials, external wall putty and cracks are mainly due to the drying shrinkage process of cement after hydration, so we should control the characteristics and mechanism of cement materials, choose cement hydration, save water, reduce and control the strength of cement and the drying shrinkage force of concrete to form functional polymer products. This is the current situation. The main cracks, the main technical solutions.

　　Otherwise, in the grass-roots problem, attention should be paid to the uniformity of the strength of the grass-roots, the difference of materials and the pre-treatment of cracks. In the construction method, attention should be paid to that the thickness should not be too thick. If the thickness is too thick, it should be divided into two or more times.

　　The key technology of putty cracking and cracking in polymer mortar wall is to fully understand the properties of cement materials. On the basis of the choice of cement hydration, it can sustain self-maintenance of water and cement, reduce drying shrinkage of cement, improve the stability of late strength of cement and functional polymer products. It can effectively fundamentally solve the problem of cracking and cracking.
