Extended Strength Development Model of Cement-Treated Clay
AbstractCement stabilization is a well-established technique involving the addition of cement to increase shear strength of soft soils. Studies on the prediction of cement-treated slurry clay generally do not cover a comprehensive suite of experiments to develop a more in-depth strength-development model, and applicability is often limited to their specific database. This paper presents a large database of unconfined compressive strength tests of cement-treated marine clay over a wide range of mix ratios and curing ages. An improved predictive strength-development model is proposed that considers the effect of mix proportions and curing duration. The actual and predicted strength values are found to agree with a correlation coefficient of 0.997. The model is also shown to be applicable to several clay and cement types; the good fit to experimental data is indicated by correlation coefficients exceeding 0.95, which is superior to existing classic prediction models.
