Criteria for the Utilization of Perlite By-products in Traditional Mortars
Climate change has become the main problems of humanity, affecting all the everyday actions and habits. The decrease of CO2 emissions is mandatory for the protection of the environment and the construction sector has a 36% share of the global problem. On the other hand, conservation of cultural heritage remains one of the main targets in European level. In the case of conservation works, the materials and the techniques used follow specific regulations included in relative norms. The aim of this work is to combine the needs mentioned above for sustainable and qualitative materials that can be used for restoration works. In this frame, the properties (chemical, physical, mineralogical, mechanical) of four perlite by-products were tested and the results were reviewed to meet the criteria set by the regulations which they will determine the possibility to use them in air lime mortar production. Fineness, color, salt content, chemical composition and reactivity were determined. The alumisilicate content of the binders was measured to comply with regulations for natural pozzolans and the pozzolanicity index of the binders was also tested. The research results to the possibility to follow specific criteria to evaluate industrial by-products, saving natural resources and increasing the environmental profile of air lime-based mortars.
