Structural behavior of load bearing brick walls of soil-cement with the addition of ground ceramic waste
An experimental study of three load bearing walls is presented and discussed in this paper. The walls were of soil-cement bricks made with three different material proportions, in which two of them had part of the cement amount replaced by crushed ceramic waste. The walls were 95.20 cm high, 75.32 c...

Zusammenfassung: | An experimental study of three load bearing walls is presented and discussed in this paper. The walls were of soil-cement bricks made with three different material proportions, in which two of them had part of the cement amount replaced by crushed ceramic waste. The walls were 95.20 cm high, 75.32 cm wide and 12.56 cm thick and had their bricks layered with cement paste. The walls were tested under compression and their displacements were measured with 5 dial gages. The walls had satisfactory behaviour and their strengths were suitable as required by Brazilian popular houses. The differences between the brick strength and the wall strength were less than 20%. A finite element analysis (FEA) was performed and the uniformity of the compressive stress distributions in the walls was evaluated. Finally, it was observed that the partial replacement of the cement by crushed ceramic waste is possible.
Neste trabalho, apresenta-se resultados do estudo experimental de três paredes estruturais, construídas com tijolos de solo-cimento. Os tijolos foram fabricados com três diferentes proporções de materiais, nas quais duas delas tiveram parte do cimento substituído por resíduo cerâmico moído. As paredes apresentavam altura de 95,20 cm, largura de 75,32 cm e espessura de 12,56 cm e tiveram seus tijolos rejuntados com pasta de cimento, que foram ensaiadas sob compressão centrada e tiveram seus deslocamentos avaliados por cinco relógios medidores de deslocamento. Observou-se comportamento estrutural satisfatório e resistências compatíveis com as requeridas pelas paredes das casas populares brasileiras. Em todos os casos, as diferenças entre as tensões máximas nas paredes e as resistências dos tijolos, foram inferiores a 20%. Para concluir o estudo, realizou-se análise por meio do método dos elementos finitos (MEF) com o intuito de avaliar a uniformidade na distribuição das tensões ao longo das paredes. Finalmente, observou-se que a substituição parcial do cimento na fabricação de tijolos de solo-cimento é viável. |
