In regions with high seismic activity, wall materials must withstand strong ground shaking without collapsing to protect lives and property, and standardized seismic performance tests have proven that the EPS cement sandwich wall panel far outperforms traditional brittle wall materials. A series of lab tests conducted by the China Academy of Building Research showed that a building using EPS cement sandwich wall panel can resist a magnitude 8 earthquake with no major structural collapse, while traditional clay brick walls would break apart under the same intensity.
The secret behind the excellent seismic performance of the EPS cement sandwich wall panel lies in its flexible composite structure. The lightweight design of each EPS cement sandwich wall panel reduces the overall building mass, which lowers the seismic force acting on the structure by 40% compared to heavy brick walls. The embedded EPS core also acts as a natural damping layer, absorbing and dissipating the seismic energy through slight deformation instead of transferring all the force to the wall structure.
Many post-earthquake reconstruction projects in Turkey, Nepal and Sichuan have adopted the EPS cement sandwich wall panel as the standard wall material, because it not only meets strict national seismic codes, but also allows fast reconstruction to help affected families move back into safe homes in the shortest possible time.
