Determinação da resistência à compressão em alvenaria de tijolos cerâmico e cimentício pelos métodos não destrutivos através de ultrassom e esclerômetria. 2016. 112f. Tese (Doutorado em Engenharia Mecânica) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2016.https://repositorio.ufrn.br/jspui/handle/123456789/23312This work fits into the technological innovation of resistant masonry as a contribution to the estimated strength of the walls and the field of non-destructive testing technique for determining the speed of propagation of the ultrasonic wave and the rebound hammer masonry line, looking for a correlation with the resistance to the compression. To do so, masonry ceramic bricks and cement blocks were studied in existing buildings of the coffin type in Muribeca’s residential complex, located at Jaboatão Guararapes county, Pernambuco, produced with different classes of resistance. Taking into account this variable tests to determine the propagation speed of the ultrasonic wave according to NBR 8802/1994, resistance to the compression compressive strength in accordance with NBR 5739/1994 and sclerometry were performed based on NBR 7584/2013. As a result obtain two graphs which relate the velocity of the ultrasound pulse with the compressive strength of the walls with a 20% uncertainty. They were also obtained three frames which make the correlation between the rebound hammer and the compression strength of ceramic and masonry cement.Acesso AbertoAlvenarias resistentesUltrassomEsclerometriaResistência à compressãoEnsaio não destrutivodoctoralThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
