Resumo Inglês:

The use of steel fibers has become more popular in recent days due to their improvement in cracking resistance. When steel fibers are added to a concrete mixture, they reduce cracks width and create a ductility mode instead of a brittle one, witch improves the deformation capacity. Steel fibers has been added to high-performance lightweight concretes, and concretes with increased compressive and flexural strength has been produced. Moreover, the addition of 0.75% of steel fibers by volume, 15% of Fly-ash and 5% of silica fume has demonstrated to be an ideal amount to obtain high-strength concretes with great mechanical properties. Hence, this paper presents a literature review about High-Strength Fibre-Reinforced Lightweight Concrete pointing out its mainly mechanical properties.
