Avaliação do comportamento endurecido do concreto autoadensável com incorporação de adições minerais nas composições dos traços. 2016. 16 f. TCC (Graduação) - Curso de Engenharia Civil, Departamento de Engenharia Civil, Universidade Federal do Rio Grande do Norte, Natal, 2016.https://repositorio.ufrn.br/handle/123456789/40612The environment aggression caused by the concrete production process has a great impact due to the high consumption of virgin raw material. However, substantially greater impact is caused by the production of Portland cement, an indispensable material used to produce concrete. The use of self-compacting concrete (SCC) appears as an alternative to reduce the environmental damage caused by the production of traditional concrete, since it allows the usage of high levels of mineral additions, such as sugarcane bagasse ashes, rice husk ashes, kaolin and active silica. Such materials, when used in combination with Portland cement and, under certain conditions, can perfectly replace high cement contents in the mixtures and still generate a significant increase of durability according to studies developed in the last decade. The use of SCC has increased significantly because of its high fluidity and cohesion characteristics and the possibility of molding in-situ without the necessity of vibration, forming a fault and void-free product which has also flowability by its own weight filling completely the molds and reaching compaction even in heavily armed structures. In this context, this study aims to evaluate the mechanical and durability properties of self-compacting eco-concretes at one year of age, with high levels of mineral additions in the mix, reducing the cement level. Five types of concrete mixtures will be analyzed, one being a self-compacting concrete with conventional materials, without mineral additions, used as a parameter, and self-compacting concrete mixtures with 40% and 50% of mineral additions to replace the cement. The expected results are that the concretes produced with a considerable reduction of the cement usage do not lose their main mechanical properties and durability, thus contributing to the sustainability of the construction industry, minimizing the environmental impacts generated.openAccessConcreto AutoadensávelEco-concretoBagaço da cana-de-açúcarCinza da casca de arrozMetacaulimAdiçõesbachelorThesisCNPQ::ENGENHARIAS::ENGENHARIA CIVIL::CONSTRUCAO CIVIL::MATERIAIS E COMPONENTES DE CONSTRUCAO
