Mechanical Properties of Gypsum-PCM Composite Refined with the Acrylic Copolymer

Abstract

Nowadays, the construction sector is changing rapidly towards more energy-efficient solutions. Many companies strive to improve the properties of building materials by reducing the weight of materials, increasing mechanical properties, and improving insulation properties. Therefore, to bring closer the problems that need to be solved, it was proposed to develop a new gypsum composite that will be used in a drywall. In addition, phase change material (PCM) and copolymer were used to improve thermal properties and tighten the final product against paraffin leakage. The main goal of the study was to check the mechanical properties. The results of endurance tests were presented. Based on that, it was determined that PCM affects the strength properties of the gypsum. In analyzing the obtained results, it can be stated from a mechanical point of view that to a certain extent, it was possible to confirm the correctness of using PCM in gypsum with an acrylic copolymer. The other part of the article presents the course of research and the results confirming the presented hypothesis.

Application of the Hot Wire Method to Measure the Thermal Conductivity Coefficient of a Gypsum Composite

“…The compressive strength test was not carried out according to the applicable standards. This was due to the comparison of the results of the compressive strength measurement from the previous study [ 22 ], where the tests according to the PN-EN 13279-2: 2014-02 standard were carried out. In addition, 105-day long-term studies were performed in this work from the production of the samples.…”
