Novel Approach to Modeling of Three Phase Strength Development of Cement Treated Clays
Reliable estimation of strength development of cement stabilised clay is beneficial in optimising cement dosage to satisfy a target desired strength performance in land reclamation and ground improvement applications. Traditional strength predictive models often adopt either hyperbolic or logarithmic model to represent the evolution of strength gain over time. However, these models generally consider only a limited range of curing ages, offering inaccurate estimates at very early or late age phases. In order to present the complete 3-phase strength development of cement stabilised clays, involving the settling, active, and inert stages, a cumulative distribution function (CDF) of the log-normal distribution is introduced. Results show matching estimates of the measured strength development over a range of clays and cements using the novel CDF approach across an extensive database collated from long term experiments in several literatures.
