Abstract: A series of physical tests and unconfined compressive shear tests were performed on reconstituted Lianyungang clays mixed with powder cement or slurry cement to investigate the effects of water content, cement content and curing time on the strength behavior of the cemented clays. A concept of quasi-water-cement ratio is proposed for predicting the unconfined compressive strength of cemented clays. The strength prediction formula proposed in this study can be used for predicting the change in unconfined compressive strength with the variation of water content, cement content and curing time, based on the laboratory test result of the cemented clay with 28days of curing time for only a given quasi-water-cement ratio. The proposed strength prediction formula can be also well applied for the test data of the cemented soils published by other independent researchers, further indicating the validity of the strength prediction formula.

Key words: strength prediction, quasi-water-cement ratio, cemented soils, curing time, liquid limit
