Though the parameter eot is deemed to reflect not only the total clay water content Cw and curing time but also the cement content Aw,
the inclusion of Aw in the ratio eot /Aw is due to the following events. First, the specimens with different cement contents can have the same void ratios after curing depending on the total clay water content
present during mixing, but may possess different levels of strength. Second, even though the samples have the same cement contents but different total clay water contents, they may still possess different levels of strength. The effectiveness of the eot /Aw ratio is further proven in Fig. 9 where the unconfined compression strengths of both field and laboratory samples reasonably follow a unique relationship with the eot /Aw ratio. Therefore
even though the experimental and field data are limited and based only on a single clay deposit (soft Bangkok clay), the following relationship has been derived to describe the unconfined compression strength of any cement-admixed clay:
