It is empirically well known that a moist fire protection material shows a good fire resistant characteristics. From this fact, a fire protection material is made of a mixture of cement mortar in which water storage materials such as silica gels or moist perlites are mixed. The latent heat of water in the fire protection material plays an important role in the resistance of temperature rise. In this study, the fire resistance tests for a fire protection material of high water content is conducted and the temperature response of the test material is obtained. The test material consists of the perlite motar in which the gels which absorbed the aqueous solution of calcium chloride are mixed as the water storage material. The water content of the test materials were also measured. And also the numerical predictions for the fire resistance test were conducted and the results were compared with the experimentally obtained temperature responses.
