New techniques have been developed with the aim of encouraging sustainable development and try to minimize the environmental degradation caused by indiscriminate extraction of natural resources and the constant generation of building waste. This research aims to evaluate the use building waste, as pozzolanic agent in the soil-lime bricks manufacture. Raw materials conventional and alternatives (waste) were characterized by tests: true specific mass, specific area, particle size analysis by sieving and laser diffraction, Atterberg limits, chemical analysis and X-ray diffraction. Technological testing specimens were prepared soil-lime on the proportion 1:10 by weight in place of lime for waste in the following proportions: 0, 10, 20, 25, 30, 40, 50 and 75%. The specimens were cured for periods of 28, 60 and 90 days in 100% relative humidity chamber, then compressive strength and water absorption were evaluated. With the best results in resistance to simple compression molded bricks were soil-lime and lime-soil-residue. The results obtained with the soil-lime bricks incorporated with residue showed values within the specifications of the ABNT, indicating that there is technical feasibility in the use of demolition waste for use in the manufacture of soil-lime bricks with no structural function.
