摘要

Methods of utilizau00c7u00e7o of tailings of elaborau00c7u00e7o of aluminium sulfate in natural rocks to fabricau00c7u00e7o materials construu00c7u00e7o cu00cdvil. Refers to compositions and manufacturing technologies of new construction materials, based on waste production natural rocks, rich with aluminium sulphate, for the production of various construction materials.This patent includes three kinds of methods (compositions and technologies) of production of the materials with different compositions and manufacturing technologies: 1.The production of solid bricks and bricks with holes through the methods of compacting tailings above appointed with waste production fell, or with lime or cement market, potrland or other materials available locally with binding properties; 2.The production of blocks of reject of the preparation process of aluminum sulfate with Portland cement, similar to the concrete blocks, through summarization of mixtures proportions chosen and homogenised, hydration and compacting them in vibra presses or presses; 3.The production of mortar tailings are appointed with residues of lime production, or falls the virgin of the market or with Portland cement, or mixtures of them in different proportions to achieve the mechanical properties desirable and economically attractive.
