Abstract
A lot of water is contained in the gypsum waste. When a fire breaks out, it becomes steam and the temperature rise is delayed. It becomes an effective fireproof coating material for concrete explosion prevention measures by constructing it to the surface of a high-strength concrete. The effectiveness was confirmed as a result of mixing gypsum waste with the light cement mortar by a current research, and examining it based on a fireproof experiment. In addition, we attempted reduction in costs by using a lot of gypsum waste like customers' needs' being answered. The fireproof coating material was given by the examination body that imitated a concrete segment and the examination body that imitated the iron frame pillar, and the fire-resistive performance was verified by the heating test.
