Alkali-activated mortars for sustainable construction material: effects of binder-to-aggregate ratio and curing conditions
Valorisation and reuse of industrial wastes has become a worldwide compelling topic to improve the sustainability of processes and materials. This paper discusses an alternative way to recycle the biomass fly ash, generated by the kraft pulp industry, to manufacture novel geopolymeric mortars intended for applications in construction. Biomass fly ash was used as a raw material, in partial substitution of the commonly used metakaolin, natural siliceous sand as aggregate. The followed manufacture process is highly simple and reproducible. Various proportions binder to aggregate were tested to study the effect on the final mortars properties. The mortars mechanical resistance was also studied …
Material and immaterial culture of the internal minor centres. Studies and researches for the ecological transition of the Madonie inner mountain area in Sicily
Presently, the European Union strategies aim at strengthening the rural areas that are characterized by a deep depopulation, people aging, and a weak employment market. In these "marginalized" areas, the urban regeneration process may be assisted by the creation of smart villages, realities that will cooperate and create innovative small towns. The Sicilian inner mountain area, in particular, consists of twenty-one villages - mostly dating back to the Middle Age - that present an attractive localization due to naturalistic, landscape and cultural features, also qualified by a well-preserved geographical area whose main building typological features were not altered during time.
