Abstract

"MATERIAIS CIMENTìCIOS REFORçADOS COM FIBRA DE CELULOSE E FIBRA NãO-CELULóSICA, ESTRUTURA DE CONCRETO CONTENDO-OS E PROCESSO PARA SUA OBTENçãO". A presente invenção refere-se a a um material baseado em cimento ou cimentício reforçado com fibras, e a um processo para sua preparação, onde a fibra de reforço é uma fibra de celulose ou não-celulósica quimicamente tratada. O material cimentício reforçado com fibra inclui (I) cimento, (II) opcionalmente, areia, agregado, ou areia e agregado, e (III) fibras de celulose quimicamente tratadas tendo um teor de cátions polivalentes de cerca de 0,1 por cento em peso a cerca de 5,0 por cento em peso com base no peso seco das fibras tratadas. A presente invenção provê ainda para um material cimentício reforçado com fibra tendo um teor de ácido fraco de cerca de 0,5 por cento em peso a cerca de 10 por cento em peso com base no peso seco das fibras tratadas.
