Abstract [en]

Fine-grained soils are often not suitable as subsoil for roads or railways or other large-scale constructions due to their sensitivity to settlements as well as their frost susceptibility. The engineering properties as well as the frost durability of such soils can be improved by stabilising it with hydraulic binders. Stabilisation is quite often used in countries with moderate climate, but seldom in cold climate. This publication presents a laboratory study of a Swedish silty sand stabilised with Multicem, a cement type containing 50% cement kiln dust. The unconfined compressive strength (UCS) was used as a measure of strength. The study investigates different binder contents and different curing times. The UCS was measured before and after 12 freeze–thaw cycles as well as after a subsequent curing time (28 d). The curing conditions were adapted to conditions as given in northern countries – that is, +4°C. The results show that the strength gained by stabilisation is sufficient even at this cold curing temperature. The strength after the freeze–thaw cycles is still significant higher than without stabilisation. The recovering time after the freeze–thaw cycles may allow a continued curing, which is indicated by a higher strength. This remaining strength should become subject for further investigation.
