Study on Thermal Properties of Plastering Mortar mixed with Paraffin type Phase Change Material

Abstract

The objective of this project is to study thermal properties of plastering mortar mixed with paraffin type phase change material. PCM used in this study is paraffin 6035 (with melting temperature of 58°C.) The test samples consist of ordinary mortar (OM) (without PCM) and plastering mortar mixed with paraffin volume fractions: 2.5%, 5.0%, 10.0% and 15.0%. Plastering mortar have thicknesses 1 and 2 cm. The tests are carried out in the laboratory. Data is collected continuously during and often testing period. The collected data is analyzed to determine the optimum PCM content. From the test’s result, plastering mortar mixed with paraffin (PPM) slow better performance in thermal properties than ordinary mortar (OM) due to heat storage at the plastering surface carry slower rate of heat transfer. The insulation properties also increases with the PCM content.
