The goal of this study is the evaluation of the use of the ash of rice peel like as addition in the production of the self-compacting concrete, together with the cement Portland. Considering the paper of 'fine' and of paste creator contributing to the properties rheologicals, it should be made a study of the fresh concrete under the point of view of the service to the requirements of acting of the concrete for this state, in matter the character self-compacting, the homogeneity, and the blending absence and of segregation. An interactive study of dosage is foreseen starting from some basic guidelines, and the tests of dispersal of the concrete are foreseen with aid of the cone of Abrams, and of segregation, besides the tests of characterization of materials, and of the other routine tests for the fresh concrete for the evaluation of the constancy of a composition. They are also foreseen the mechanical tests for the evaluation of the mechanical resistance, in way it validates the studied compositions. (AU)
