The manufacturing of Portland cement is responsible for a big amount of energy and greenhouse gas (GHG) emission. Therefore, to date, it is imperative to find alternative materials to replace a major part of cement for sustainable concrete constructions. The present study forms a part of an on-going research project on the application of new cementitious matrices produced using different types of recycled materials. In particular, it focuses on the use of pulp and waste paper to partially replace Portland cement at varying percentages for producing a new lightweight mortar, frequently named papercrete. The development of this economical and eco-friendly material may permit of recycling a big amount of waste paper leading to lower housing costs with also ecological benefits. To this scope, an experimental campaign in the laboratory is carried out to characterize this new innovative material from a physical and mechanical point of view. The preliminary results of this on-going experimental campaign are illustrated and commented on in this paper. The obtained results confirm the possibility of applying this partially-recycled material as a possible alternative for strengthening existing panels of masonry.
The traditional Mediterranean architecture shows the balance between nature and human activities, whose conservation has to consider the local characters and the low recovery technologies and lead to the recovery design, by favoring the criterion of minimum intervention.
The research has found a complete systematization from the identification of housing types representative of the historical construction materials (calcareous sandstone and stone block) present in Puglia and Basilicata regions. Consequently you can assess the energy and static vulnerability of the pre-consolidation state and identify qualitatively and verify quantitatively the traditional recovery solutions, exportable on similar constructive units present in other environments
The Sassi of Matera are a unique example in the world of rock settlements, developed from natural caves carved into the rock and molded into increasingly complex structures inside two large natural amphitheaters. Research focuses on the compatibility of the energy efficiency measures applied in Sassi buildings with the recent MiBACT guidelines on "Energy efficiency improvements in cultural heritage" and AiCARR guidelines on "Energy efficiency of historical buildings". The paper aims to analyze energy and environmental performance of different building typologies and monuments of the Sassi site
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
