Soils, rocks and concrete are the principal materials a civil engineer encounters in practice. This book deals with the material analogies, their implications in property characterization, giving attention to similar as well as dissimilar methods in respect of each of these three materials. It provides an integrated, systematic approach for realistic assessment of engineering properties of soils, rocks and concrete. Geotechnical engineers, civil engineers and materials scientists will be interested in this volume.

model. They conclude that the models using three fitting parameters provide the best fit over a wide range of suctions. Models for soil-water characteristic curves are only useful if we have experimental data on which to base them. Agus, Leong and Rahardjo (Singapore) present a large number of experimental soil-water characteristic curves determined for two types of residual soil from Sigapore. They present data for eight different sites. This data set allows them to relate the parameters of the soil-water characteristic curves to index properties. They conclude that the relationships derived are suitable to pro vide a quick preliminary estimate of a soil-water characteristic curve. The importance of soil-water characteristic curves is emphasized by another con tribution dealing with this topic. Aung, Rahardjo, Leong and Toll (Singapore) inves tigate the relationship between mercury intrusion porosimetry measurements and soil-water characteristic curves. The porosimetry measurements are presented as soil-air characteristic curves. The slopes of the soil-air characteristic curves are found to be similar to the slopes of the soil-water characteristic curves. The equiv alent pore diameters calculated from the mercury entry value and the air entry value appear to be related. Therefore, it is suggested that porosimetry data can be used to construct an estimate of the soil-water characteristic curve.

This Book Brings Out The Possibilities Of Generalizations Of Behaviour Of Soils And Hence Of Predicting The Required Engineering Properties Without Elaborate Testing. We Recognize That A Single Approach Cannot Be Evolved For All Soil Types And Hence The Necessity For Classifying Soils Into Different Categories And To Use Appropriate Model For Each. First Of All, Based On Mechanism Of Stress Transfer And Interaction Between The Phases, Two Obvious Classes, The Fine Grained And Coarse-Grained Soils Have Been Differentiated.The Discussions Bring Out That Because Of Identical Mode Of Stress Transfer, The Mechanical Behaviour I.E., Compressibility, Shear Strength Relations, Permeability Variations Etc. Can Be Generalized For All Fine Grained Soils, Enabling The Prediction Of Behaviour Of Such Soils With Just The Knowledge Of Certain State And Index Properties. The Sequence Of Discussion Is On The Characterization Of Specific Soil States And Prediction Of Proportion Starting From The Ideal Saturated Uncemented Soils, Both Normally And Over Consolidated, Cemented Saturated Soils And Partly Saturated Soils.In Dealing With The Behaviour Of Coarse Grained Soils, The Importance Of Microfabric And The Difficulties In Possible Generalizations Are Discussed. Perhaps The Unique Feature Of This Book Is That The Division Of The Chapters Is Based On Different Soil States, All The Mechanical Behaviours Being Discussed Under Each Soil State.The Book Will Be Of Interest To Both Academicians And Practising Engineers, Researchers And Postgraduate Students. It Would Serve As A Textbook For Undergraduate Students With Prior Knowledge Of Basic Soil Mechanics.
