Polymer Support Fluids in Civil Engineering

Description

The aim of the book is to provide the practising geotechnical/foundation engineer with an introduction to fluidsupported excavation processes, a brief history of the use of polymers in excavation support with discussion of past successes and importantly reasons for failures. It will include a specification for the use of polymer fluids and all the information necessary to optimise the use of these materials and the performance of the resulting foundation elements.

The book will cover all major aspects, from the fundamental material properties to site testing and case histories of polymer use.
