## Abstract

A series of laboratory tests were performed on cemented silty soils to understand their strength behavior. With the same cement content, the greater the water-cement ratio is, the lower the unconfined compressive strength of cemented silty soils is; with the same water-cement ratio, the greater the cement content is, the higher the unconfined compressive strength of cemented silty soils is. At the same time, the test results indicate that the unconfined compressive strength increases linearly with the inverse of quasi-water-cement ratio which is defined as the ratio of the total water weight to the cement weight before mixing, and the maximum quasi-water-cement ratio of original soils is a fixed constant. The method of predicting the unconfined compressive strength is discussed for cemented silty soils. With the unconfined compressive strength of cemented silty soils of 28 days under specific cement content and water-cement ratio, the unconfined compressive strength of cemented silty soils of other curing time, cement content and water-cement ratio can be predicted. The relationship between the maximum quasi-water-cement ratio and the liquid limit of original soils is also investigated. The relationship between the maximum quasi-water-cement ratio and the liquid limit of cemented silty soils does not fit the existing empirical formula, its variation regularity is contrary to the latter.
