In accordance with the present invention, there are provided novel fiber reinforced building material formulations, comprised of an inorganic binding agent and synthetic fibers. The fibrous material employed in invention formulations is capable of undergoing progressive fibrillation upon agitation. As a result, tougher building materials, due to higher fiber addition rates than previously possible, are produced. Formulations containing Portland cement-based compositions and fibrillating synthetic fibers are also contemplated. In addition, there are provided methods of producing fiber reinforced building materials, including Portland cement-based compositions, and articles produced therefrom.
L'invention concerne de nouvelles formulations de matériaux de construction renforcés par des fibres, lesquelles formulations sont composées d'un agent de liaison inorganique et de fibres synthétiques. La matière fibreuse employée dans les formulations selon l'invention est capable de subir une fibrillation progressive lorsqu'elle est malaxée. On obtient donc des matériaux de construction plus durs, étant donné qu'il est possible d'ajouter des taux de fibre plus élevés qu'auparavant. L'invention concerne également des formulations contenant des compositions à base de ciment Portland et des fibres synthétiques de fibrillation. En outre, l'invention concerne des procédés de production de matériaux de construction renforcés par des fibres comprenant des compositions à base de ciment Portland, ainsi que des articles fabriqués à partir desdits matériaux.
