In this study, a combination of Capric (CA)-Palmitic acid (PA) with optimum mass ratio of 85–15% is used and impregnated with recycled concrete powder (RCP). The resulting composite is produced as foam concrete and tested for a series of physico-mechanical, thermal and microstructural properties.
This study integrates micro-encapsulated phase change material (MPCM) into the AARS foamed concrete, aiming to balance its mechanical properties and thermal performance for sustainable building applications.
The stability of the PCMs, the problems in relation to using them in concrete, as well as their thermal performance in concrete are also presented.

The impact of foamed cement containing MPCMs on building energy consumption was analyzed in five different climate zones in China using EnergyPlus. The results show that energy savings are more significant in cities with higher heating demand.
The compressive strength, thermal conductivity, pore microstructure, and thermal storage characteristics of the two types of phase change foamed concrete were tested and analyzed.
Phase change material (PCM)-enhanced concrete offers a promising solution by enhancing thermal energy storage (TES) and reducing energy demands for heating and cooling in buildings. However, challenges related to PCM leakage, mechanical strength reduction, and encapsulation durability hinder widespread adoption.
The findings indicate that increasing the thermal conductivity and enthalpy will substantially improve the thermal performance of phase change heat storage concrete blocks. A CFD model was used for the thermal simulation of concrete wallboards infused with PCMs (Essid et al., 2022).
The possible incorporation of phase change materials (PCMs) in building materials has attracted a lot of research interest worldwide due to the concern on global warming and the ability of PCMs to reduce energy consumption in building because of their thermal energy storage abilities.
Moreover, bio-based materials offer significant environmental benefits due to their renewable nature, biodegradability, and low carbon footprint (Ahmed et al., 2022). When combined with PCMs, these materials can further enhance the thermal storage capacity of concrete (Baylis & Cruickshank, 2023).
