This paper examines the thermal performance of 20 different mortar mixes, which were prepared in order to study the behaviour of mortar incorporating Phase Change Materials (PCM). The PCM was used at a rate of 10, 20 and 30% by weight of total solid materials. Silica fume was added to the mixes by 10, 20, 30 and 50% by weight of cement to enhance the mortar properties. Mortars which incorporate phase-change materials (PCM) have the capability to help regulate the temperature inside buildings, contributing to the thermal comfort while decreasing the amount of mechanical heating and cooling energy required, therefore they have the potential to reduce building carbon emissions. The mechanical characteristics and physical properties of the mortar with PCM were studied. The results show that mortar with Phase Change Materials up to PCM20% can be used with an optimal compressive strength. Silica fume (SF), up to a 20% SF addition, enhanced the mechanical properties of the mortar.

Ultrafine Cement

By mixing several binder materials and additions with different degrees of fineness, the packing density of the final product may be improved. In this work, ultrafine cement and silica fume mixes were studied to optimize the properties of cement-based materials. This research was performed in mortars made of two types of cement (ultrafine Portland cement and common Portland cement) and two types of silica fume with different particle-size distributions. Two Portland cement replacement ratios of 4% and 10% of silica fume were selected and added by means of a mechanical blending method. The results revealed that the effect of the finer silica fume mixed with the coarse cement enhances the mechanical properties and pore structure refinement at a later age. This improvement is somewhat lower in the case of ultrafine cement with silica fume.
