Abstract

The control of carbon emissions and energy conservation, and environmental protection are hot spots of global concern. In this paper, phase change paraffin wax is applied to porous materials for adsorption and storage, and nature’s eco-friendly materials are selected as the porous matrix to propose an eco-friendly phase change concrete using eco-friendly materials as raw materials. It was obtained that the strength of the phase change concrete utilizing environmentally friendly materials was 25.4% to 36.8% lower than that of ordinary concrete, while some of the phase change light aggregates were found to produce slip damage with the cement paste in the damage study. By constructing a small-sized test room for thermal properties, we obtained a phase change concrete that utilizes environmentally friendly materials to control the temperature better than the commonly studied phase change concrete, with a peak temperature drop of up to 2.6°C in the phase change test room compared to the normal test room and a delay in the peak temperature.
