This paper presents a study of the physical and mechanical properties of ceramic mass with the incorporation of waste ash wood, sludge from water treatment and rice husk ash to determine whether its future use manufacture of bricks. The procedures consisted in the chemical and mineralogical characterization, particle size analysis and design of mixtures with clay and waste through planning technique. Bodies were produced by uniaxial pressing, with variations of compositions in the range of 0 to 50% waste and 50 to 100% clay. The burning was carried out in muffle furnace. The physical and mechanical properties evaluated were water absorption and modulus of rupture strength. The main result, it was concluded on the feasibility of using compositions with up to 25% of waste at temperatures of 800, 900 and 1000ºC.
