Abstract

FIBRAS POLIMÉRICAS PARA REFORÇO DE CONCRETO. A invenção é direcionada a uma fibra macrossintética que consiste em três ou mais filamentos parcialmente fundidos feitos de uma composição de polímero compreendendo pelo menos um polipropileno, em que a fibra tem uma forma de seção transversal multilobal com três ou mais lóbulos. A invenção também é direcionada a um método para produzir fibras macrossintéticas, a um material cimentício compreendendo um aglutinante e fibras macrossintéticas da presente invenção e a um método para formar uma superfície de concreto usando uma mistura de concreto modificada com as fibras macrossintéticas da presente invenção.
