Engineering Properties of Treated Soft Clays: an Experimental Investigation and Modelling

This book presents experimental and numerical investigations for the effects of cement and lime treatment on compressibility, permeability, stress-strain, strength and stiffness behaviour of three soft clays. Effects of cement treatment on physiochemical and micro-structural properties have also been investigated. X-ray Diffraction, Scanning Electron Microscopy, particle size distribution, pH measurement, organic content, electrical conductivity, cation exchange capacity, exchangeable cation, water content, unit weight, specific gravity, and Atterberg limits tests were conducted to examine physiochemical and micro-structural properties. Compressibility and permeability properties of untreated and, cement and lime treated clays were investigated by performing one-dimensional consolidation tests. Stress-strain, strength and stiffness behaviour of untreated and, cement and lime treated clays were evaluated by performing unconfined compression tests. Consolidated drained direct shear, triaxial compression tests were also carried out to assess the strength-deformation characteristics of treated clays.
