“…It was shown that the thermal conductivity coefficient, compressive strength, and dry unit weight decreased depending on the increase in porosity. 10,34 This situation can be associated with the decrease in the use of BA and especially EP in this paper. In addition, there is a strong relationship between these features.…”

“…Since cement is a material that has a strong effect on weight, the parameter B had the greatest effect on dry unit weight and its value was 150, which corresponded to the lowest cement dosage. 10,14 On the other hand, the importance of the parameter C-EP/BA reduced to the second order because BA was also a very lightweight material and the optimum value of the parameter C was EP/BA = 1. Although EP has relatively lighweight, the EP/BA level not being optimal at the highest level can be attributed to the extreme brittleness of the EP material.…”

Perlite and some recycled materials are preferably used to provide thermal insulation and lightness in mortar. Cement is often used as a binder in such a composite, although it makes the composite heavier and impairs its insulation properties. In this study, recycled bottom ash (BA) and expanded perlite (EP) as the aggregate, and cement as the binder and the optimum solution were investigated by using Taguchi Method. Depending on the specimens prepared using orthogonal array L9, the values of compressive strength, flexural strength, flowability, dry unit weight, water absorption, capillarity coefficient, and thermal conductivity coefficient were calculated. In general, it was found that the cement dosage was the most effective parameter and the thermal conductivity coefficient increased in parallel with the increase in unit weight and strength.

Design and Thermal Characterization of Two Construction Solutions with and without Incorporation of Macroencapsulated PCM

et al. 2022

Improving the energy efficiency of new and existing building stock while fostering the use of renewable energy is one of the major goals of the Renovation Wave initiative promoted by the European Union. In this framework, the present research focuses on the design of an innovative and efficient construction solution for an external envelope and internal partitions that can improve energy efficiency and thermal comfort in lightweight construction technology for buildings. The use of phase change materials (PCMs), particularly in the macroencapsulated form, in building construction solutions or components enhances the buildings’ thermal mass without significantly increasing the solutions’ weight. Therefore, the solution herein developed is essentially targeted at lightweight building technology since the incorporation of a macroencapsulated PCM core will allow to store and release large amounts of energy per volume unit, in order to attenuate high indoor temperature fluctuations. In the scope of this study, the use of a thermally active core in a lightweight construction solution was designed and thermally characterized. Thus, an experimental campaign on the thermal properties of the solution containing macroencapsulated PCMs was performed, intended for applications in two twin full-scale cold-formed steel lightweight tiny houses. Regarding the hot box heat flux meter approach, the results revealed the following: good correlation between thermal conductivity and mean specimen temperatures for both construction assemblies tested, and significant thermal amplitude reduction with the use solution containing the macroencapsulated PCM core.
