Clay–Water∕Cement Ratio Identity for Cement Admixed Soft Clays

Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 131, Issue 2

Abstract

The in situ deep mixing technique is an established means of enhancing bearing capacity and reducing settlement by placing columnar inclusions in soft ground. Developments in equipment and field techniques to implement this method have surpassed the basic understanding of strength development in soft clays admixed with cementing agents at water contents close to their liquid limit or higher. Laboratory tests on soft clays admixed with cementing agents are a prerequisite for engineering decisions on the proper mix proportions for intended field strength. This paper presents and analyzes test results on cement admixed soft clays within the basic framework of induced cementation of soft clays. It is possible to propose a clay–water∕cement ratio formulation that enables calculation of cement contents consistent with changes in in situ water content.
