Abstract

Patente de Invenção: <B>''FIBRA DE AçO PARA REFORçO DE CONCRETO DE ALTA PERFORMANCE''<D>. Uma fibra de aço (10) para reforço de um concreto ou argamassa de alta performance tendo um comprimento na faixa de 3 mm a 30 mm, um espessura na faixa de 0,08 a 0,30 mm, e uma resistência a tensão maior que 2000 MPa. A fibra de aço é proprocionada com entalhes (12, 14), em que a dimensão na direção perpendicular ao eixo longitudinal da fibra de aço é de 50%da espessura. Estes entalhes proporcionam um reforço eficaz do concreto de alta performance, sem influenciar a habilidade de misturar-se das fibras de aço em um sentido negativo.
