Abstract
A series of short term isotropically consolidated drained triaxial compression tests was conducted to investigate the influence of cementation, total curing time and strain rate on the stress-strain behaviour of cement-mixed kaolin. The research suggests that the behaviour of cement-mixed kaolin can be described by a unique stress-plastic strain-time relationship independently of strain (curing) history. Both the peak strength and the small strain stiffness were observed to be dependent on the total curing time. The small strain stiffness normalised for stress level showed a continuous linear increase with logarithm of total curing time, while the tested samples of cement-mixed kaolin reached an apparent plateau for peak strength after about one day of curing. The post-peak critical state strength was in contrast seen to be constant with curing time. In relation to findings in the literature and in this study, the coupling of ageing and viscous effects is discussed. It is suggested that there must be a point (characteristic strain rate) at which the behaviour of both artificially and naturally structured clays changes from being dominated by ageing effect to being predominantly viscous.
