Abstract
Lightweight concrete may be defined as the concrete of substantially lower unit weight than that made from gravel or crushed stone. Surface improvement liner represents the controlled permeable formwork (CPF) liner is an innovative material used to improve the quality of the cover region, by allowing the air bubbles and mix-water to drain out from the surface of concrete whilst retaining cement and other fine particles. Accordingly, this not only minimises the porosity of the surface area of concrete, but it also helps towards improving or enriching the actual content. This paper reports an experimental study carried out to investigate the effect of liner on strength properties of lightweight concrete. The results showed that there is significant improvement in the strength and near surface concrete quality in CPF liner than that of conventional lightweight concrete.
