Figs. 3 and 4 show the effect of volume fraction on average crack
spacing and maximum crack width of specimens subjected to restrained shrinkage. The average crack spacing decreases with increasing volume fraction. The maximum crack width decreases significantly with the addition of steel fibres but the decrease is not as significant when the volume fraction of fibres increase beyond 1.0 to 2.0%.
