Abstract

Highlights: Integration of PCM into concrete screed slab to contribute to energy efficiency. Compression and bending strength characterization of concrete incorporating PCM. Resistance losses of 66% and 52% in compression and bending respectively. Energy storage capacity of the concrete incorporating microencapsulated PCM. Abstract: Evolution towards sustainable building design is a current goal worldwide, shaping codes and policies, to achieve such goal the construction industry and sector requires new energy saving concepts and building materials. The objective of this study is to quantify the influence of microencapsulated phase change material (PCM) over the concrete mechanical and thermal properties. The experimental tests on concrete with PCM yielded resistance loss up to 66% and 52% for compression and bending strength respectively, comparatively with the reference concrete specimens, without PCM. Thermal performance of concrete incorporating PCM was also evaluated. The results showed that the incorporation of PCM can contribute to reduce the energy demand in buildings.
