Concretes with a high thermal energy storage capacity were fabricated by mixing microencapsulated phase change materials (MPCM) into Portland cement concrete (PCC) and geopolymer (GPC). The effect of MPCM on performance compressive strength PCC GPC investigated. It was found that the replacement sand resulted in lower conductivity higher storage, while specific heat remained practically stable when material (PCM) liquid or solid phase. Furthermore, as function concentration reduced at rate...
The effect of frost conditions on the physical and mechanical properties geopolymer concrete (GPC) Portland cement (PCC) containing two different micro-encapsulated phase change materials (MPCM) was examined. Microstructural studies revealed that freeze-thaw induced deterioration can be contributed to microcracks appearing at weak interfacial transition zones between paste/aggregate paste/MPCM. addition MPCM provided an excellent resistance against cycles with minor reduction compressive...
Microencapsulated phase change materials (MPCM) were added to geopolymer concrete (GPC) for utilization as a thermal energy storage passive building applications. Three different MPCM compared examine the influence of hygroscopic nature shell, PCM core/polymer shell ratio, and size on microstructure, properties compressive strength GPC. The combination polymer high core/shell small found improve interface bonds between microcapsules GPC matrix, increase capacity GPC, results in good...
The volatile compounds that comprise lavender essential oils, including linalool and linalyl acetate, have demonstrative therapeutic properties. supercritical CO2 extraction (scCO2) has demonstrated efficiency selectivity for the of oils from vegetable matrices. solubility oil in scCO2 was determined using a high-pressure variable-volume modeled by semiempirical models. Supercritical carried out at pressure 180, 250 300 bar temperature 40–60 °C, with without cosolvents. kinetic curve been...
Microencapsulation of PRS paraffin wax was carried out by means suspension-like homopolymerization methyl methacrylate (MMA) and the copolymerization this monomer with acrylate (MA) methacrylic acid (MAA). The influence type monomers their proportion as shell materials, mass ratio polyvinylpyrrolidone to (PVP/monomers), (PRS/monomers) on properties phase change material (PCM) microcapsules has been studied. analytical techniques used for characterization particles were differential scanning...
The potential of utilizing geopolymer concrete (GPC) walls containing microencapsulated phase change material (MPCM) in buildings at different environmental conditions has been investigated. effect climate (temperature, solar radiation) and MPCM design (shell thickness, concentration) on the energy efficiency was systematically analyzed based numerical calculations finite differences method with an balance approach. found to increase higher levels addition for thicker walls. When outdoor...
To reduce pollution and global warming, the energy consumption needs to be decreased. Incorporation of Phase Change Materials (PCMs) into building materials can help lower needed cool warm buildings, while keeping indoor temperature at a comfortable level. However, incorporation PCMs construction alter their performance. In this study, effect addition two different Micro-encapsulated (MPCM) geopolymer concrete (GPC) Portland cement (PCC) pastes was investigated. The samples were examined...
Non-isocyanate polyurethanes (NIPUs) based on biobased polyamines and polycarbonates are a sustainable alternative to conventional (PU). This article discloses novel method control the crosslinking density of fully isocyanate-free polyurethanes, synthesized from triglycerides carbonated previously in scCO2 different diamines, such as ethylenediamine (EDA), hexamethylenediamine (HMDA) PriamineTM-1075 (derived dimerized fatty acid). As capping substances, water or bioalcohols used way that can...
