Resistencia mecánica de ladrillos preparados con mezclas de arcilla y lodos provenientes del tratamiento de aguas residuales

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 ºC to 1100 ºC. 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.
