The project search evaluate the utilization potentialities of ash of rice peel like pozolanas so as to if it acts together with the lime in soils chemical stabilization processes. Must be adopted two contents of ash to the soil, 5 and 10% with regard to the soils weight, to they act in collaboration with the lime, and the processes will be compared to the soils cases stabilized with the lime only, whose content is defined in 8% of the dry weight. Must be accomplished the soils characterization rehearsals and compact parameters identification, for then if it proceed the bodies reproduction of proof for the variation mechanical resistance evaluation to the simple compression, according to cures different ages. The cure conditions must be standardized in humid chamber. The reactivate of the soils must be outlet for inference with base in the values of mechanical resistance evolution. (AU)
