- Influence of curing conditions on lime and lime-metakaolin mortarsPublication . Faria, Paulina; Martins, Ana Isabel G.Air-lime mortars with or without pozzolanic components were largely used in historic buildings. Due to natural or accidental degradation it is often necessary the application of repair mortars, durable and compatible with the masonries of historic buildings. Within this context and associating the improvement of mortars characteristics to the necessity of sustainable construction practices, some mortars formulated with lime and the addition of pozzolans have been studied. In previous papers, the influence of some types of air-lime (powder hydrated lime or lime putty) and the addition of metakaolin in lime mortars have been presented. Each type of mortar presents its specificities. In pure lime mortars the setting occurs by carbonation and in lime-metakaolin mortars it occurs both by carbonation and hydration. A crucial question in order to optimize the characteristics of the mortars (and its applicability) is related with the curing conditions. This article describes an experimental campaign with different pure air lime mortars and lime-metakaolin mortars, cured under different conditions of relative humidity and CO2 content. Properties of the mortars, mainly in terms of mechanical behaviour and open porosity, capillary water absorption and drying capacity, are obtained, compared and discussed. The benefits in some properties revealed by the different mortars are correlated with the laboratorial curing conditions and with in situ applications possibilities.

- Avaliação da introdução de resíduo da indústria têxtil em argamassasPublication . Pereira, Cristiana Gonilho; Martins, Ana Isabel G.; Faria, Paulina; Fangueiro, RaulO setor têxtil produz uma grande quantidade de resíduos de natureza fibrosa e, embora a sua utilização na construção seja hoje uma realidade, a acumulação destes resíduos em aterros sanitários continua a ser uma preocupação. Tendo em vista o desenvolvimento sustentável, através da diminuição da acumulação destes resíduos e da promoção da sua reutilização, apresenta-se o desenvolvimento da aplicação de resíduos fibrosos com aplicação técnica, na construção. Este artigo apresenta a caracterização de argamassas de cimento reforçadas com fibras resultantes da indústria têxtil e pretende demonstrar a influência da dosagem de fibras no desempenho das argamassas.

- Um sistema ágil na gestão da construçãoPublication . Fernandes, Manuela Cristina TimóteoAtualmente a indústria da construção civil vive uma das maiores crises dos últimos tempos, a juntar a alterações legislativas muito exigentes. As empresas de construção evidenciam então necessidades de se adaptarem a este novo mercado, ao cliente mais exigente, às inovações tecnológicas, aos ciclos de vida curtos dos produtos e aos custos reduzidos. A agilidade é assim uma capacidade que as empresas podem desenvolver para sobreviver e prosperar neste ambiente de negócio tão turbulento, impondo a si próprias práticas ágeis. No processo da construção existem vários intervenientes: Clientes, projetistas, construtores, fiscais, certificadores, fornecedores de produtos, pelo que se torna exigível que exista uma entidade que regule, que comunique e que imponha as boas práticas, e que acima de tudo “AGILIZE O PROCESSO”. Para este objetivo considera-se ser a Fiscalização, a entidade que melhor pode desempenhar estas funções, recorrendo de um condutor tecnológico. O AgileConstruct é um sistema proposto para agilizar o processo, que permite o arquivo, a partilha de toda a documentação, o controle do planeamento e a comunicação online entre todos os intervenientes. Este sistema foi testado numa obra pública tendo sido verificada e validada a sua eficácia na obtenção de um produto com maior qualidade e menor custo.
- Sustainability as architecture for people: the case of football stadiumsPublication . Lucas, Susana; Afonso, Armando Silva; Ferreira, VictorThe football stadiums are a center of emotions. In use the assembly is of thousands of people in a short period of time, a few hours. The sustainability of these sports facilities can not only be associated with its construction and operation. In 2011 the Quality Manual of Stadiums developed by UEFA appears the concept of Sustainable Architecture - Architecture for people. The concept of "architecture for people," emphasizes the need for well-being, comfort, and both psychological and physical, which should be an integral feature of any construction project sustainable. This can be defined as sustainable architecture for the planet and for people. Sustainable architecture can be considered as a simple, but important to the human scale, psychology, culture and ergonomics. It also encourages the design sensibility and interpretation that seeks to go beyond the basic requirements of the customer and therefore aims to give added value to the project. Sustainable architecture also focuses on the importance of creating a sense of place and encourage social interaction, which is particularly significant buildings, such as stadiums, where the idea of promoting the community is very important. This can be promoted through a variety of additional activities and facilities within the stadium complex that can offer the community recreation options as needed, without forgetting the business benefits they will bring to the development of the stadium itself. Thus presents the current situation of the Euro 2004 stadiums in relation to the parameters of Sustainable Architecture defined by UEFA as well as what they can improve, given that facilities that are still present only one fifth of its useful life. Football stadiums can thus leverage new forms of interaction, connection and even change their mindsets thousands of users.
- Improving by sustainability in sport facilitiesPublication . Lucas, Susana; Afonso, Armando Silva; Ferreira, VictorSporting structures particularly in Portugal, which were built for Euro 2004, in addition to belonging to clubs, the rest, have a very low utilization rate. But all in general have high operating costs and little control in the use of resources available. From the cases of stadiums Letzigrund, Zurich, Switzerland and Amsterdam Arena, the Netherlands, there may be a new vision for the improvement of Portuguese stadiums. In the case of the stadium was the Letzigrund stadium in its construction was dubbed the Green Stadium, built for Euro 2008. Among the recommended measures were implemented immediately: Green roof: with a photovoltaic system with an area of 2500 m2 and Solar Thermal Collectors 90 m2, heating by pellets; Promoting green transport: public transport; Waste management by implementing reusable cup; Lighting System: Minergie. The Amsterdam Arena, even having been built in 1998, has now the objective for 2015, be the first zero carbon stadium. The Amsterdam ArenA strives: to be a platform for sustainable innovations; to reduce our own environmental impact, and that of our events; to be a good neighbor and a positive boost for the economy; to increase our sustainable impact together with others. It presents an analysis of the measures advocated by these two football stadiums for sustainability, and measures can be defined and advocated an example and be applicable in Euro 2004 stadiums. It is considered that the implementation of measures for sustainability in sports facilities can be made throughout his life in order to have lower cost and operating efficiency.
