Abstract

''MATERIAIS à BASE DE CIMENTO, REFORçADOS COM FIBRAS E TENDO MAIOR TENACIDADE E DUCTILIDADE'' Descreve-se um sistema reforçador de fibras híbridas, que aumenta a ductilidade de concreto em aberturas de fissuras pequenas e grandes, e ao mesmo tempo evitando a necessidade de usar fibras de aço em altos volumes (como por exemplo, 1%), levando em consideração o módulo de Young, desenvolvendo altas razões de área superficial para volume, a fim de obter melhor ancoragem, e usando comprimentos relativos diferentes.
