The safety performance of building materials in real earthquake scenarios is the most convincing proof of their quality, and EPS Cement Sandwich Panel has shown very excellent performance in many practical seismic tests and actual earthquake events. The lightweight characteristic greatly reduces the mass of the wall, so the inertial force generated during an earthquake is far smaller than that of a heavy brick wall, avoiding the huge destructive force that the wall applies to the main structure. The flexible connection structure between the panel and the main frame allows the wall to move slightly with the main structure during an earthquake, absorbing seismic energy instead of resisting it rigidly, which greatly reduces the probability of wall fragmentation and collapse. In many post-earthquake reconstruction projects, buildings built with EPS Cement Sandwich Panel have shown very good integrity, with only slight cracks at the panel joints, and no large-area wall collapse that causes casualties. This reliable seismic performance has been recognized by many seismic research institutions, making the panel widely recommended for residential and public building construction in high seismic intensity zones. It not only meets the national seismic design code requirements but also provides an extra layer of safety protection for people’s lives and property.
