Abstract
Recycled polyethylene (R-PE) fibres from discarded waste fishing nets are used as fibre reinforcement in cement-based mortars for control of plastic shrinkage cracking. A thin, fresh mortar overlay is cast directly on top of a restraining concrete substrate and placed under controlled environmental conditions. Mortar overlays with the addition of R-PE fibres up to 2.0 vol% were tested and compared to mortar overlays with a 0.2 vol% addition of commercially available PP fibres. The cracking behaviour is monitored using a digital image correlation (DIC) technique allowing measurements of strain and displacement fields on the
overlay surface. The R-PE fibres were successful in controlling the plastic shrinkage cracking of restrained mortar overlays for fibre fractions of 2.0 vol%.
