“…The porous inclusion technique follows the impregnation of PCM into the porous inclusions, and that composite material can be used in concrete for improving the thermal insulation [ 90 ]. Among these techniques, the research on PCM-filled lightweight aggregate and its effect on mechanical and thermal performance has been widely conducted [ 91 , 92 ]. Hitherto, concrete was specifically designed to obtain robust mechanical properties and durability.…”

“…However, certain recent attempts, such as the coating of PCM containing LWA, the use of nanomaterials in PCMs, pipes filled with PCM, the use of supplementary cementitious materials in concrete to overcome the degradation effect of PCM, and PCM impregnation into concrete pores from the surface, all show performance improvements of PCM-containing concrete [ 91 , 148 , 149 ]. Jafarabad et al [ 28 ] reported that the compressive strength was improved by 25% by using the silica fume in a cement matrix and polyethylene glycol as a PCM compared to a specimen without silica fume.…”

“…Similarly, PCM deposited into PVC pipes and then embedded into the concrete pavement is an efficient technique to improve the performance of concrete [ 152 ]. Haider et al [ 91 ] investigated the interaction of low-temperature phase change material with concrete prepared with lightweight aggregate. The normal aggregate was replaced with 50% and 100% epoxy coated and PCM impregnated lightweight aggregate.…”

The use of phase-change materials (PCM) in concrete has revealed promising results in terms of clean energy storage. However, the negative impact of the interaction between PCM and concrete on the mechanical and durability properties limits field applications, leading to a shift of the research to incorporate PCM into concrete using different techniques to overcome these issues. The storage of clean energy via PCM significantly supports the UN SDG 7 target of affordable and clean energy. Therefore, the present study focuses on three aspects: PCM type, the effect of PCM on concrete properties, and connecting the outcome of PCM concrete composite to the United Nations sustainable development goals (UN SDGs). The compensation of reduction in strength of PCM-contained concrete is possible up to some extent with the use of nanomaterials and supplementary cementitious materials. As PCM-incorporated concrete is categorized a type of building material, the large-scale use of this material will affect the different stages associated with building lifetimes. Therefore, in the present study, the possible amendments of the different associated stages of building lifetimes after the use of PCM-incorporated concrete are discussed and mapped in consideration of the UN SDGs 7, 11, and 12. The current challenges in the widespread use of PCM are lower thermal conductivity, the trade-off between concrete strength and PCM, and absence of the link between the outcome of PCM-concrete composite and UN SDGs. The global prospects of PCM-incorporated concrete as part of the effort to attain the UN SDGs as studied here will motivate architects, designers, practicing engineers, and researchers to accelerate their efforts to promote the consideration of PCM-containing concrete ultimately to attain net zero carbon emissions from building infrastructure for a sustainable future.

Refrigeration plays an important role in several sectors in 21st-century life, such as food, air conditioning, healthcare, industry, and energy. In food industry it plays a vital role for reducing the post-harvest losses and in the preservation of food products. In this paper different amounts of a microencapsulated paraffin having a melting temperature of À10 C were used as phase change material (PCM) for the preparation of multifunctional rigid polyurethane foams (PUF) for refrigeration applications. The processability issues, the microstructural and thermo-mechanical properties of the resulting panels were comprehensively investigated. Morphological analysis evidenced a tendency of the incorporated PCM to damage the original closed cell structure of the PUF, and a fully open-cell microstructure was obtained for PCM contents higher than 20 wt%. Differential scanning calorimetry (DSC) evidenced a proportional correlation between the PCM concentration while the thermal energy storage efficiency of the prepared panels was also confirmed by monitoring the trend of the inner temperature in cubic specimens subjected to programmed heating and cooling ramps. Concerning the mechanical response, flexural tests evidenced that the stiffness of the foams was not substantially influenced by the PCM content, while a heavy drop of the failure properties was detected.
