- Des+construção sénior, sentimento e teatroPublication . Inácio, Catarina Madruga; Wengorovius, Rita; Antunes, DavidNo âmbito do Mestrado em Teatro da Escola Superior de Teatro e Cinema, com especialização em Teatro e Comunidade, desenvolvi um trabalho de projeto com uma comunidade sénior pertencente à Fundação Liga. O objetivo primordial foi criar e construir sonhos com esta comunidade através de ferramentas teatrais, demonstrando assim que o teatro contribui para o desenvolvimento e bem estar da comunidade, neste caso a sénior. O projeto culminou na apresentação do espetáculo DES+CONSTRUÇÂO no dia 3 de Março de 2013 criado por todos os elementos do grupo. Um espetáculo realizado pela comunidade e para a comunidade, refletindo os seus obstáculo mas também as suas alegrias e vitórias.
- Durability performance of self-compacting concrete (SCC) with binary and ternary mixes of fly ash and limestone fillerPublication . Raposeiro Da Silva, Pedro; De Brito, JorgeThe basic objective of this work is to evaluate the durability of self-compacting concrete (SCC) produced in binary and ternary mixes using fly ash (FA) and limestone filler (LF) as partial replacement of cement. The main characteristics that set SCC apart from conventional concrete (fundamentally its fresh state behaviour) essentially depend on the greater or lesser content of various constituents, namely: greater mortar volume (more ultrafine material in the form of cement and mineral additions); proper control of the maximum size of the coarse aggregate; use of admixtures such as superplasticizers. Significant amounts of mineral additions are thus incorporated to partially replace cement, in order to improve the workability of the concrete. These mineral additions necessarily affect the concrete’s microstructure and its durability. Therefore, notwithstanding the many well-documented and acknowledged advantages of SCC, a better understanding its behaviour is still required, in particular when its composition includes significant amounts of mineral additions. An ambitious working plan was devised: first, the SCC’s microstructure was studied and characterized and afterwards the main transport and degradation mechanisms of the SCC produced were studied and characterized by means of SEM image analysis, chloride migration, electrical resistivity, and carbonation tests. It was then possible to draw conclusions about the SCC’s durability. The properties studied are strongly affected by the type and content of the additions. Also, the use of ternary mixes proved to be extremely favourable, confirming the expected beneficial effect of the synergy between LF and FA. © 2015 RILEM.
