  • 摘要:In the present paper an experimental investigation on water retention properties of lightweight cemented soils (LWCS) taking into account the effects of air foam content and curing time is presented. This experimental study, aimed at determining the suction range corresponding to significant changes in water content, is preliminary to future investigations devoted to durability properties of LWCS systems against wetting and drying cycles. Test results showed that water retention capacity is slightly affected by the curing time for the considered time interval (i.e. 30 and 90 days). Furthermore, the addition of air foam does not affect water retention properties of treated samples. Large voids are present in the samples as footprints of air bubbles added upon mixing, leading to an increase of the porosity of samples without altering the microstructure of the matrix.
