Abstract:

Using of passive systems to improve Indoor Air Quality (IAQ) could be very useful in terms of energy savings and comfort of occupants. This study focused on an innovative and multifunctional mortar able to improve IAQ. The action of photocatalytic binder coupled with adsorbent materials used as aggregates was investigated. Results show better water vapour permeability and moisture buffering capacity, and lower mechanical properties of unconventional-aggregate based mortars with respect to the traditional ones. With respect to VOC, depollution capacity of the former was up to 65% higher than the mortar prepared with sand. The addition of UV irradiation positively influences depollution capacity even in presence of conventional aggregate.
