However, no matter what kind of material form, the mixed-use development has a key feature, that is the close physical and functional connection among the various parts of the project
In this material form, each single building has no common basis, but are linked through some sort of connection body in the ground or air.
This 'compact unit' mode on the community scale, not only greatly improved the compact space and function, but also greatly enhanced the overall operating efficiency and the quality of the space environment . 6 References [1] Bi Jun.Construction Path of the Low Carbon City on the Post-crisis Era [J].Nanjing Social Sciences ,2009（11）：12-16

Peel away the fiber sheet material that damage specimens stuck outside, found in the fiber cloth surface sticks has the 2-5 mm mortar, this suggests that fiber cloth and concrete have enough bonding strength between them; Internal core concrete has nearly pressure crisp, but the shape keep intact; Central to the concrete specimens are obviously a drum, has completely crushed and with the core concrete completely separated, seen in Fig. 3.
