【Abstract】 From the point of gradient material, the function-structure compound design was put forward. Double structure or multiple structure were selected according to different functional requirement. The decoration and property optimization of the whole structure could be realized by adding the design of functional structure on the common concrete. The coated surface layer, decorative function layer and basic structure layer were combined organically by using the special construction technique. The test results show that the three stage gradient changes of the decoration and the physical mechanical performance are realized through the scientific design of materials and structures, such as: gradient changes as strength of 90-70, 80-40, 50-30 MPa and ion diffusion of 667,780-(1 000), (1 310) C etc. The optimization of the material, structure and performance are obtained through it.更多还原
