Balloon dust and steel slag are two residues generated in the steel industry with potential use as aggregates in civil construction. The soil-cement block allows more economy and sustainable constructions, also improving ambience´s aspects. The use of waste to produce the soil-cement matrix further enhances the reduction of costs and environmental impacts. The objective of this work is to quantify the performance increase in soil-cement blocks due to the use of a mixture of balloon dust and steel slag. The percentage of incorporation of the mixture of the two residues varied from 0% to 8% of the total soil´s mass. The evaluated parameters were the water absorption and the compressive strength of the blocks. The replacement of the residue by the soil did not modify the water absorption values, these values being always those required by the regulations (absorption below 20%). In the case of replacement of soil by residue in an amount of 8%, with respect to the total soil´s mass, the increase in compressive strength was 15%. For all the soil-cement recipes studied, the compressive strength was always higher than that required by the regulations (>2.0 MPa).
