摘要

Following growing awareness concerning indoor air quality and energy efficiency, two different solutions became prominent in this research field: latent heat storage capabilities (for energy savings) and photocatalytic mortars (for elimination of air pollutants and self-cleaning). Indoor air quality in buildings is now going far beyond the simple indoor temperature regulation. Aspects like contamination of the indoor air by pollutants, are gaining importance and being included into building regulations. These functionalities, heat storage and self-cleaning, have been always considered separately, so the products available so far only include one. With the increasing demand for new and more innovative materials, future research will tend to include several functionalities in one single product.ududWithin this work a new multifunctional mortar combining energy storage, self-cleaning and air depolluting capabilities has been developed. The paper discusses the manipulation of mortars microstructure, by studying the microstructural modifications with different amounts of PCM (phase change material) and nanoparticles of titanium dioxide. Using the correct combination of both additives, the mechanical strength will not be compromised. The paper demonstrates that it is possible to develop new advanced mortars for building applications, more complex and with multiple functions, opening a new field of opportunities for the construction sector.
