Reutilização de resíduo sólido industrial, constituído por areias de fundição, na fabricação de tijolos maciços e peças decorativas

The present work is a result of a research that investigated the technical viability for the reuse of the solid waste generated by foundry sands agglomerated with clay, for application in the sector of the civil construction and in decorative pieces. For that, the investigation established a methodology, which evaluated the stabilization of the waste in solidified matrices of Portland cement, improved with the addiction of silica fume and/or fluidificant additive. Two compositions had been used in the confection of massive bricks and decorative pieces. The obtained bricks had been submited to tests of compressive strength, water absorption and solubilization, The obtained results proved the technical viability for apply the briks in the execution of masonry and to produce decorative pieces, that which presenting excellent aggregated value and potencial to commercialize them.
