AB  - Tensile strength might be considered as Achilles heel o f concrete, especially when it comes
to No-Fines Light-Weight Concrete (NFLWC) where there are inherent weaknesses in its mechanical properties.
Many techniques are available to improve these properties, among them and one of the best techniques is
introducing fibres in the concrete mass. In this study, the effect of incorporating waste-plastic fibres
(an environmentally non-friendly material usually causing pollution) on the mechanical properties of NFLWC
was investigated experimentally. Two main variables were considered, namely, the fibres volume fraction which
was taken in the range of 0.0-1.5% and the fibres aspect ratio (8.16 and 24). It has been shown that the addition
of waste-plastic fibres to the no-fines light-weight concrete mix succeeded in increasing both its compressive
and tensile strength. The density of the trialled NFLWC mixes is also discussed.
