Abstract：
Bluestone slate has many excellent characteristics, such as light weight, water imperviousness and corrosion resistance, etc. Wet sticking process is used to stack and press the bluestone slate basal edge at the upper layer onto the bluestone slate at the lower layer, realizing a natural drainage form similar to tile roof. ZTE Nanjing R&D Center Phase III engineering adopts European style design and uses stacking wet sticking process to satisfy the shape-building requirements of external wall and roof, and to realize the simple and practical effects.
