Interface and internal compatibility in a copper fibre cement composite

P. Kittl、V. Martínez1993-09-01Materiales de Construccion

This paper presents the mechanical behaviour of a compacted composite formed by short ductile copper fibres randomly distributed in portland cement matrix. The samples, a half with fibres and the other without them, were subjected to compression fatigue. So, 1 hertz and the value of stress corresponding to the 1% of t…
