This article is about the methods and techniques used in the building "retrofit" in modernist style designed by the architect Affonso Eduardo Reidy in the fifties, and also about the project of the new Rio de Janeiro MIS (Museum of Image and Sound), under construction, by The North-American office Diller Scofidio + Renfro, both located in the city of Rio de Janeiro. These constructions present a wide view of the concept of sustainability, not commonly used in public buildings in Brazil. In the building designed by Reidy, which belongs to the State of Rio de Janeiro, the regeneration to host the new headquarters of the State Department of Taxation and Finance respected its original characteristics and used smart and sustainable design techniques, as well as recyclable materials. On the other hand, the project of the new museum at Copacabana Beach was entirely planned on sustainable bases and it includes the application of building techniques concerning that purpose. This article presents a study of these two cases and evaluates the techniques and materials used in one another. Observing the principles of sustainability in construction is a pioneering initiative of the State Government. This article aims at making the scientific community aware of the needs of immediate adoption of sustainability techniques in Civil Engineering, not only in the construction of new buildings, but also in the regeneration of the existing ones, as well as the need of imperious adoption of sustainable techniques when it comes to maintainability. 相似文献

就化学的观点分析了水对不同胶凝材料产生的不同作用,列举了相关水泥著作中所阐明的不能将胶凝材料(即使是硅酸盐水泥)与水的反应笼统地称为水化反应之观点.胶凝材料与水的反应实际上有水解、水化反应,水还可以起溶解反应物的介质作用,甚至水不是反应物而是生成物. 相似文献
