Effect of phase change material on mechanical and thermal properties of cementitious composites

Abstract

Cleaning the snow/ice formed on the pavement surface during winter months causes great time loss and high labor costs. In this context, phase change materials (PCM) can be considered as an effective alternative for cleaning the snow/ice on the pavement surface. In this study, microencapsulated PCM (mPCM) was added to cement mortars at 0%, 2%, 4%, 6%, 8% and 10% by weight of cement. The prepared cement mortars' flexural strength, compressive strength, and ultrasonic pulse velocity were investigated. In addition, to observe the effect of mPCM on thermal properties, reference, and 6% mPCM, added mortar samples of 100 mm × 100 mm × 20 mm were produced, and thermocouples were placed inside them. As a result, it was observed that the mechanical properties of cement mortars decreased as the mPCM ratio increased. However, the mechanical strength of cement mortars remained sufficient for many structural applications. Thermal property tests showed that mPCM added mortars heated and cooled down slower than the reference mortar. This is important, especially in regions with a very high day-night temperature difference. Cracking, one of the biggest problems seen in cement-based pavements and caused by the day-night temperature difference, can also be reduced with mPCM.
