Abstract

The preparation of high-quality, large-size cohesive soil deposits is possible using the slurry method and is practicable if a suitable soil material is used. The requirements for such a soil are discussed and the results of a survey of available ingredient materials presented. A testing program of six trial soil mixtures is described, including consolidation of slurry in a special apparatus. Each trial soil is evaluated, and detailed properties of the selected material, called Cornell clay, are presented. The results from a series of CIUC triaxial tests show that Cornell clay has normalized strength parameters similar to many naturally occurring cohesive soils. Supply sources for the ingredient materials are given.
