Influence of basalt fibres on free and restrained plastic shrinkage
Abstract Early-age cracking due to plastic shrinkage is often attributed to reducing the durability of concrete structures. The objective of this paper is to evaluate the potential use of chopped basalt fibres in preventing these cracks. Testing was undertaken to measure the magnitude of shrinkage strain that develops in unrestrained specimens, and the severity of cracking that occurs when shrinkage is restrained. Results indicate basalt fibres are effective in preventing cracks by reducing the magnitude of free shrinkage, and by restricting the growth of cracks if they do occur. The latter mechanism is more prominent when the w/c ratio is decreased.
