加固材料的各项力学性能应优于被加固材料，其物理性能应接近被修补材料．这样，修补后便能长期与被修补材料共同承担各种破坏作用，达到修补加固的目的．无机粘结胶具有上述性能．在工程中应用获得良好的社会效益．
The mechanical properties of the reinforcing material should be better than that of the reinforced material, and its physical properties should be close to that of the repaired material. In this way, after repair, it can be used for a long period of time in conjunction with the repaired material to bear all kinds of damage and achieve the purpose of repair and reinforcement. Inorganic cement has the above properties. Applied in the project to obtain good social benefits.
