近年来、随着建筑工业的发展和人民生活水平的提高,这样就促使建筑工业广泛采用装配式钢筋混凝土大板结构来加快建设速度。因此用聚合物油膏之类的嵌缝材料牢固而耐久地保护装配式结构的接缝问题,就具有特殊的意义。对嵌缝材料的基本要求是:在建筑物整个使用过程中、要保持弹性、对结构物[混凝土、构件木材]表面要具有良好的粘结性、在温度变
In recent years, with the development of the construction industry and the improvement of the people’s living standards, this has prompted the construction industry to widely use prefabricated reinforced concrete slab structures to speed up construction. Therefore, it is of special significance to use a caulking material such as a polymer ointment to firmly and permanently protect the joint structure of the fabricated structure. The basic requirements for caulking materials are: to maintain elasticity throughout the use of the building, to have good adhesion to the surface of the structure [concrete, component wood], change in temperature
