Abstract: In this study, PCM based on paraffin’s adhered to a silica-based matrix appear to be a suitable option in the search for techniques for incorporating Phase Change Materials (PCM) into Portland cement mortar mixtures. When water is added, though, paraffin particles have been seen to elude the silica matrix. There is a paucity of information on how the use of such PCM impacts mortar behavior. Portland mortar mixtures with 15%, 20%, 25% and 30% PCM content were developed using Portland cement in order to assess the impact of this PCM addition. Both fresh and dry samples were examined for physical characteristics like concentration, accessible pore volume, relative density, and water absorption. According to the results, more cement and water are needed in the PCM-Silica added mixtures compared to regular mortar mixtures to achieve comparable compressive strengths & flexural strength. Here is 20% PCM mixtures had a highest tensile strength of 13.45 MPa, whereas 25% PCM mixtures had values 10.99 MPa. As a result, the proposed study broadens our knowledge of PCM cement mortar mixture behavior and proportioning.
