13. Contribuições para a ciência e engenharia de materiais cimentícios: processamento, durabilidade e resistência mecânica. / Contributions to science and engineering of cementitious materials: processing, durability and mechanical strenght
A engenharia de materiais proporcionou os avanços mais notórios sobre o desempenho mecânico dos materiais cimentícios nas últimas décadas, ora por meio das técnicas de conformação, ora pelo projeto da microestrutura. Com isso, demonstrou-se ser falsa a idéia de que baixas resistências mecânicas seriam inerentes aos materiais cimentícios, mas, ao

14. Comparative analysis of costs in the structure of buildings of armed concrete when projected by the NBR-6118:2003 and NBR-6118:1978 / Análise comparativa do custo da estrutura de edifícios de concreto armado quando projetados pela NBR-6118:2003 e NBR-6118:1978
In March of 2004 the new version of the Brazilian Code for design of concrete structures, the NBR 6118(2003), has replaced its predecessor the NBR 6118(1978). Amongst the new presented concepts, the greatest impact is related to the question of the durability of the concrete structures. The present work evaluates the influence of the new normative criteria,

15. Study of the interface between the concrete and the material for repair by using microscopy / Estudo da interface entre o concreto e o material de reparo mediante microscopia
During the history of the Civil Engineering, it is witnessed the appearance of a new age, which emphasizes quality in general, and durability, in particular, of the concrete structures. As a result of a continuable search for quality, an evolution in a relatively new field is observed, named Structural Pathology, which relates to the study of structural impe
