| Abstract: | The PCM technology, which has important research value for the energy conservation in construction and the solution of energy shortage, becomes a hot topic in the field of materials in recent years. Diatomite and expanded graphite are taken as the adsorption substrate in this research,on which the wax based PCM（the phase change point of the wax is moderate）are adsorbed on them. Then the three-ele- ment composite PCM are made and mixed into the cement mortar. The power plant slag is also used as the fine aggregate replacing the sand, in order to make the light-weight and high-strength thermal storage floor. By using solar energy or the industrial waste heat,the PCM store heat intermittently, so as to realize the energy conservation and environmental protection. The findings of the simulation test of the PCM floor model indicate that the PCM floor possesses commendable heat storage capacity and economic and environ- mental benefits. The achievement provides an efficient approach to the warm supply in south areas of Chi- na, in order to relieve the energy shortage due to the central heating. |
