Abstract
<B>MéTODO PARA FABRICAçãO DE CONCRETO PROJETADO E COMPOSIçõES DE CIMENTO ASSEMELHADOS E DE TAIS COMPOSIçõES<D>. A invenção provê misturas de cimento, particularmente, para uso como elementos de ligação de concreto. O concreto projetado resultante tem características de consolidação rápida da ordem de 5 a 10 minutos, rápida alta resistência à compressão (5 a 25Mpa após duas horas de cura, 20a 60Mpa após um dia de cura), alta resistência permanente à compressão e encolhimento desprezível. Clínquers de cimento torrados de alto contéudo de alumínio com gesso, anidrita, cal, cal hidratada, bentonita e outros aditivos são usados nas misturas. São especialmente adequadas para uso em engenharia do concreto projetado. Os métodos de uso do concreto projetado melhorado são similares aos daqueles fabricados com cimento Portland comunm, com rebote na obra significativamente reduzido.<B> METHOD FOR MANUFACTURING DESIGNED CONCRETE AND SIMILAR CEMENT COMPOSITIONS AND SUCH COMPOSITIONS <D>. The invention provides cement mixtures, particularly, for use as concrete connecting elements. The resulting shotcrete has characteristics of rapid consolidation of the order of 5 to 10 minutes, fast high resistance to compression (5 to 25Mpa after two hours of curing, 20 to 60Mpa after one day of curing), high permanent resistance to compression and negligible shrinkage. Roasted cement clusters of high aluminum content with plaster, anhydrite, lime, hydrated lime, bentonite and other additives are used in the mixtures. They are especially suitable for use in shotcrete engineering. The methods of using improved shotcrete are similar to those made with common Portland cement, with significantly reduced rebound on the construction site.
