Burning a concrete building is a catastrophic event that poses significant threats to human life and the environment. Sima, as a construction material, is designed to be durable and resistant to fire, but under extreme heat conditions, it can become unstable and collapse. The intense heat generated by the fire can cause the concrete to crack and weaken, potentially leading to the collapse of the entire structure.
