{"title":"Enabling thermal energy storage and mechanical enhancement in concrete containing CO2-cured core-shell structured phase-change lightweight aggregates","authors":"Ewald Kuoribo, Dongxing Xuan, Chi Sun Poon, Daniel Wai Ming Chan","doi":"10.1016/j.jobe.2026.117467","DOIUrl":"https://doi.org/10.1016/j.jobe.2026.117467","url":null,"abstract":"The porous structure of lightweight aggregates (LWAs) makes them an effective medium for the absorption of phase change materials (PCMs). However, their incorporation into concrete as aggregates is largely constrained by liquid-state PCM leakage and strength degradation. This study presents a CO<ce:inf loc=\"post\">2</ce:inf>-cured core-shell structured strategy for phase-change lightweight aggregates (C-CS-PCLAs) to achieve thermal energy storage and mechanical enhancement in concrete. C-CS-PCLAs were produced by impregnating LWAs with paraffin, pelletizing steel, and ground granulated blast-furnace slag powders as partial cement replacements, and then subjected to CO<ce:inf loc=\"post\">2</ce:inf> carbonation. The leakage characteristics, physical properties, and thermal performance of the individual aggregates were systematically evaluated, followed by concrete scale trials. Macro-scale thermal regulation was monitored using an infrared thermal camera, while structural viability was validated through compressive strength testing. The results show that the C-CS-PCLAs, with an average CO<ce:inf loc=\"post\">2</ce:inf> uptake of 7.65%, exhibit a dense structure that reduces porosity, limits water absorption to below 11%, and mitigates PCM leakage by more than 50%. Furthermore, the resulting aggregates maintained thermal stability, achieved a latent heat storage capacity of 11–21 J/g, show enhanced particle strength alongside increased thermal conductivity. At the concrete scale, replacing 100% of the raw LWAs with C-CS-PCLAs reduced surface temperature by up to 7.5 °C compared to the reference concrete samples under heat exposure. The 28-day concrete compressive strength reached 35–54 MPa, restoring the strength loss associated with uncoated PCLAs in concrete. Ultimately, the core-shell design for PCLAs leverages calcium-rich industrial solid waste to create a resource-efficient and promising aggregate for enabling thermal energy storage in high-strength construction materials.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"3 1","pages":"117467"},"PeriodicalIF":6.4,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149123845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
