“…The 63.2% porosity was obtained for GPC‐SSPCM‐100. The greater porosity of GPC as well as the weak interaction between PCMs and the binder are the main reasons reported in literature 32 . Sukontasukkul et al 22 demonstrated that incorporating paraffin as phase change material determined improving the thermal properties of lightweight GP.…”

The cooperation between phase change materials (PCMs) and geopolymer (GP) is energy-efficient way for improving the thermal performance of construction materials. This study discusses the effect of PCM combination with GP matrix on obtained concretes' mechanical and thermal properties. Attapulgite/lauric-capric acid eutectic mixture (ATP/LCEM) composite was fabricated as shape-stable composite phase change material (SSPCM) and then integrated with GP concrete (GPC) for improvement of the thermal mass of buildings. Thermal, mechanical, physical, morphological, thermal energy storage (TES) characteristics, and solar thermoregulation performances of the developed GPC-SSPCMs were experimentally characterized. The compressive strength was found over 6 MPa for GPC without aggregates (only SSPCM). The compressive and flexural strengths were relatively low, but above the requirements of the current standards. Other properties as thermal conductivity and solar performance make the produced GPC-SSPCMs promising materials for advanced TES applications in buildings. The apparent porosity was around 45% for GPC-SSPCM-50 and 63% for GPC-SSPCM-100, while water adsorption around 21% for GPC-SSPCM-50 and 30% for GPC-SSPCM-100. Thermal conductivity values of 0.375 W/mK for GPC without aggregates recommended this material as an insulator. The produced SSPCM composite melts at 19.00 C with corresponding latent heat of 73.9 J/g, while the GPC-SSPCM melts at 18.30 C with corresponding latent heat of 6.57 J/g. Based on the obtained outcomes, the energy-saving was determined as 5.56 kWh, which is corresponding to the CO 2 saving of 15 kg-CO 2 , 14.68 kg-CO 2 , and 2.41 kg-CO 2 in case of using coal, natural gas, or electricity, respectively as energy source.

“…2 Phase change materials (PCM), with their capacity for endothermic and exothermic effects during phase transitions, 3 possess a distinctive capability to store and release energy, 4 thereby enabling diverse forms of energy storage such as solar thermal energy storage for heating purposes, 5 utilization of industrial waste heat, 6 and integration of PCM with building materials to facilitate year-round temperature regulation. 7 Additionally, PCM can enhance the energy conservation efficiency of existing temperature-control equipment. 8 In brief, widespread implementation of PCM for effective energy storage and utilization holds potential to curtail energy consumption while addressing challenges associated with limited energy supply and uneven distribution.…”

Wood-based phase change materials (WBPCM) have the potential to significantly reduce energy consumption in plywood structures, but the quest for a streamlined production strategy to facilitate their industrialization remains a formidable challenge. In this work, phase change plywood (PCP) was prepared by phase change adhesive (PCA), in which urea-formaldehyde resin (UF) served as the adhesive and different contents of paraffin wax (PW) as phase change materials (PCM). The use of PCA enabled the efficient and simplified production of wood-based composites with excellent energy-saving properties. By combination of the low thermal conductivity of wood with the energy storage capabilities of PCA, PCP demonstrated a high latent heat capacity of 67.53 J/g at 47.6 °C. 2D correlation Fourier transform infrared (2D FTIR) was carried out to analyze the phase transition mechanism. By adding PCA, the heat transfer time of PCP-3 from 40 to 55 °C was extended by 181%, compared with conventional plywood, which indicated an excellent energy-saving ability. Furthermore, finite element simulation was conducted to statistically simulate the thermal transition process of PCP. Our work presents a strategy for the design of phase change plywood with excellent energy-saving properties, while also enabling large-scale production.

“…3 Geopolymers have a lot of advantages such as good formability, simple and easy manufacturing, low cost, 4 reduced CO 2 emissions, energy consumption, and the problem of landfilling of waste materials, 5 as well as providing good mechanical strength and durability. 6 The geopolymer structure was defined as an amorphous or nanocrystalline aluminosilicate gel. Depending on the type of alkali activator, the gel structure is defined as N-A-S-H and K-A-S-H, where alkali cations act as charge balancers.…”

Admixtures used in concrete have been produced for conventional concrete and the behavior of these additives in geopolymer/alkali‐activated systems is still complicated. In this study, the effects of different types of water‐reducing admixtures on the fresh and mechanical properties of Class F fly ash‐based geopolymer mortars and alkali‐activated slag mortars were investigated. For this purpose, flow diameter, rheological examination, compressive and flexural strength tests were carried out. The data obtained showed that the admixtures used in the study did not have a positive effect on the fresh properties of geopolymer/alkali‐activated mortars, and the improvements in the flow properties were due to the extra water contributed by the admixture. The flow diameters of the mixtures containing the same amount of water with the mixture containing plasticizer were generally higher than those of the mixtures prepared with the admixture up to 10.3% in the fly ash‐based mortars and 15.4% in the slag‐based mortars. Addition of plasticizers reduced the compressive strength of fly ash‐based geopolymer and slag‐based alkali‐activated mortars up to 31.7% and 29.7%, respectively.
