RECYCLING SPENT COFFEE WASTE FOR INNOVATIVE THERMO-PLASTERS: DEVELOPMENT OF A PROTOTYPE
This paper presents an experimental study aimed at testing the real energy performance of a thermo-plaster prototype made of an ordinary mortar boosted by various percentages of spent coffee ground. That is one of the wastes of the brewing process that are usually disposed of in landfill with great concerns for the possible environmental footprint due to its organic nature and possible harmful components. In this paper, the mortar was manufactured froman ordinary Portland cement and sand, partially substituted by the waste. Specimens characterization is briefly outlined and a careful examination of the thermal properties is carried out. A plastering prototype was manufactured and placed in …
Building the space: vaults’ geometry and stereotomy. Materials and architectural technologies in the Mediterranean area
Costruire una volta ha sempre nei secoli rappresentato un’arte pratica che si nutriva del contributo di chi operava in cantiere: indispensabile risultava la tecnica, il sapiente taglio della pietra e l’opportuna collocazione della stessa nel gioco statico dell’organismo murario. Un sapere tecnico, questo, che combinava l’estetica con la organizzazione strutturale della fabbrica costruenda; l’esperienza pratica aveva dettato a muratori e scalpellini i precetti in merito ai differenti compiti organizzativi e alle relative gerarchie degli esecutori dell’opera edilizia, all’attrezzature e alle macchine da cantiere, agli utensili e alle lavorazioni da usare, incentivando una spiccata attitudine …
