“…However, some supporting materials with very low thermal conductivity also cause a decrease of the thermal conductivity of the organic form-stable PCMs. [101] When the thermal conductivity of the recyclable supporting materials was lower than that of PCMs, it would make a certain decrease in the thermal conductivity of the form-stable PCMs. For instance, Xiong et al [38] used industrial waste sludge incorporated ash (SIA) as a skeleton and NaNO 3 as PCMs to prepare the form-stable PCMs.…”

With the expansion of the global population, the energy shortage is becoming increasingly acute. Phase change materials (PCMs) are considered green and efficient mediums for thermal energy storage, but the leakage problem caused by volume instability during phase change limits their application. Encapsulating PCMs with supporting materials can effectively avoid leakage, but most supporting materials are expensive and consume huge of natural resources. Carbon materials, which are rich and renewable resources, can be used as economical and environmentally friendly supporting skeletons to prepare form‐stable PCMs. Although many researchers have begun to use recyclable materials especially various derivatives of carbon as supporting skeletons to prepare form‐stable PCMs, the preparation methods, thermophysical properties and applications of form‐stable PCMs with recyclable skeletons have rarely been systematically summarized yet. Form‐stable PCMs with a recyclable skeleton can be used as green and efficient thermal storage materials due to their high heat storage capacity and good thermophysical stability after 2000 thermal cycles. This review investigates the effects of recyclable skeletons on the thermophysical properties including phase change temperature, latent heat, thermal conductivity, supercooling, and thermal cycling reliability. Four major kinds of recyclable skeletons are focused on: biomass, biochar, industrial by‐products as well as waste incineration ash. Additionally, the application scales of form‐stable PCMs with recyclable skeletons are explicated in depth. Moreover, the main challenges confronted by form‐stable PCMs with recyclable skeletons are discussed, and future research trends are proposed. This article provides a systematic review of the form‐stable PCMs with recyclable skeletons, giving significant guidance for further reducing carbon emissions and promoting the development of sustainable energy.

“…However, limited studies are available in this area [ 310 ]; hence, continuous research and motivation are required to develop the use of PCMs in concrete structures without affecting the traditional properties of concrete. In addition, achieving passive cooling [ 335 ] and long-term stability with microencapsulated PCMs in concrete requires further investigation in order to realize its potential application in real concrete structures.…”

Supplementary cementitious materials (SCMs) and chemical additives (CA) are incorporated to modify the properties of concrete. In this paper, SCMs such as fly ash (FA), ground granulated blast furnace slag (GGBS), silica fume (SF), rice husk ash (RHA), sugarcane bagasse ash (SBA), and tire-derived fuel ash (TDFA) admixed concretes are reviewed. FA (25–30%), GGBS (50–55%), RHA (15–20%), and SBA (15%) are safely used to replace Portland cement. FA requires activation, while GGBS has undergone in situ activation, with other alkalis present in it. The reactive silica in RHA and SBA readily reacts with free Ca(OH)2 in cement matrix, which produces the secondary C-S-H gel and gives strength to the concrete. SF addition involves both physical contribution and chemical action in concrete. TDFA contains 25–30% SiO2 and 30–35% CaO, and is considered a suitable secondary pozzolanic material. In this review, special emphasis is given to the various chemical additives and their role in protecting rebar from corrosion. Specialized concrete for novel applications, namely self-curing, self-healing, superhydrophobic, electromagnetic (EM) wave shielding and self-temperature adjusting concretes, are also discussed.
