Title: On the use of different wastes to formulate mortars for sustainable building materials
Biography: Andrea Saccani
Circular economy and low-impact materials production are the desired targets of the future. In the field of building materials, Portland cement based mortars are being questioned because of their high CO2 footprint. Geopolymers matrix may offer an alternative to the traditional binders, particularly when deriving from industrial wastes. In the present study, the possibility to formulate alkali activated blends made of metakaolin and up to a 50 % wt, bottom ashes deriving from urban waste incinerations is investigated. Moreover, to increase the mechanical properties in particular to reduce brittleness and increase flexural strength and increase the dimensional stability of mortars scraps deriving from the production of epoxy-carbon fiber have been recycled in the same materials without any chemical or high temperature treatments. Positive results have been obtained thus supporting this recycling route.
