Phase-change energy-storing composite foam concrete block
The invention discloses a phase-change energy-storing composite foam concrete block which includes a foam concrete block body. A cement-base phase-change material is composited onto an inner side wall of the foam concrete block body and is composed of following components: 48-80% of cement, 0-30% of fly ash, 1.5-3% of re-dispersible latex powder, 0.1-0.3% of cellulase, 0.3-1% of fiber, 10-25% of a shaped phase-change energy-storing material, 0-1% of a water reducing agent and 0-1.5% of a water repellent agent. The cement-base phase-change material is directly poured onto one side wall of the foam concrete and the phase-change energy-storing composite foam concrete block is obtained after hardening maintenance. The concrete block has both a thermal-insulation performance and a temperature-self-adjustment performance, can store heat at a high temperature and release the heat at a low temperature to maintain a relative constant indoor temperature, thereby further enhancing a building energy-saving effect. The concrete block, when being used for wall body, is high in surface strength, is convenient to construct, is leakage-resistant, is good in durability and can satisfy a requirement of energy saving in buildings.
