Thermal energy storage is based on sensible and/or latent thermal energy storage methods [14]. With the sensible method, heat is released or stored by lowering or raising the thermal mass material''s temperature. Whereas with the latent method, heat is released or stored as a material''s phase change [15]. The amounts of sensible and latent …
The thermal performance of the phase change materials depends on the melting temperature, thermal conductivity and energy storage density. Among the different types of PCM suitable for thermal energy storage, the most suitable material is one with a fast melting and solidification point [15]. Not all existing PCM''s can be used for thermal …

When the drum is almost horizontal (inclination ≈ 0°), more energy is provided to the concrete because more concrete is lifted to the full diameter of the drum before dropping. It is during the drop that the concrete is knitted and mixed. Therefore, the higher the drop, the higher the energy imparted to the concrete.

For e.g., concrete has energy storage capacity of 0.91 kJ/kg K −1 whereas a commonly used PCM known as paraffin wax has energy storage capacity of 174.4 kJ/kg. It means that concrete will store thermal energy equivalent to paraffin wax when the temperature rise of almost 175 K will occur [ 18 ].
Research on phase change material (PCM) for thermal energy storage is playing a significant role in energy management industry. However, some hurdles during the storage of energy have been perceived such as less thermal conductivity, leakage of PCM during phase transition, flammability, and insufficient mechanical properties. For …
