GARCIA UBAQUE, César Augusto; GARCIA VACA, María Camila  and  VACA BOHORQUEZ, Martha Lucía. Mechanical Resistance of bricks made of mixtures of clay and sludge from sewage treatment. Tecnura [online]. 2013, vol.17, n.38, pp.68-81. ISSN 0123-921X.

This work discusses the mechanical properties of bricks that were made with clay and sludge mixtures. We analyzed 100:0, 99:1, 95:5, 90:10, 80:20 and 60:40 proportions of clay and sludge. Bricks were cooked between 35 °C to 1100 °C. The sludge used in this study came from sewage treatment plant of G.M. Colmotors Company. These tests were carried out: Water Absorption and mechanical resistance of bricks compression. The results of this study showed that the best percentage of sludge to mix with clay was 5 % to 10 %. Since, this percentage range meets the quality standards of the product demanded in Colombia.

Keywords : clay products; testing of materials; industrial waste disposal.
