The aim of this research was to study the effect of vegetable wastes addition on physical and mechanical properties of soil-cement bricks. It was used two types of wastes (rice and Brachiaria brizantha rusk). The Portland cement content used on the soil stabilization was of 10. The combinations of cement and vegetable wastes contents varied from 100 of cement content and 0 of wastes content to 60 of cement content and 40 of waste content. The bricks were submitted to the compression tests and to the water absorption test. The best results, in terms of compression strength and water absorption capacity were reached by the 10 addition of vegetable wastes in substitution to the cement. The results suggest the promising use of these wastes, at the 10 content, without the commitment of the mechanical properties related to the resistance and to the water absorption capacity of the soil-cement bricks.
