Building energy consumption is one of the main sources of global energy consumption, and improving building energy efficiency is crucial for achieving sustainable development.
Phase change materials (PCM) can effectively regulate indoor temperature and reduce energy consumption in buildings by absorbing and releasing latent heat during the phase change process.
However, there is a risk of leakage when traditional PCM is directly added to concrete, and shape stabilization needs to be achieved through supporting materials.
Silica fume (SF) and rice husk ash (RHA), as industrial/agricultural wastes, can both stabilize PCM and serve as auxiliary cementing materials, but their effects on PCM stability and thermal performance in foam concrete are still unclear.
In this study, a shape stabilized PCM insulation board based on foam concrete was developed, and its mechanical properties and thermal performance were systematically tested.
