His major areas of research interests include unsaturated soil behaviour, ground improvement techniques, geoenvironmental engineering and use of waste materials in civil engineering applications. He has published 21 papers in respected international journals. Dr. Thyagaraj received the IGS-Prof. Dinesh Mohan Award in 2016. Currently he is an editorial board member of the International Journal of Geotechnical Engineering.
The book comprises select proceedings of the 2016 annual conference of the Indian Geotechnical Society (IGC 2016), with technical papers on the theme “Ground Improvement and Geosynthetics”. The papers cover a wide range of topics, including chemical modification using admixtures, microbial-induced carbonate precipitation, geopolymers, fly ash and other industrial wastes, modification using geosynthetic materials such as natural and synthetic fibers, expanded polystyrene (EPS) geofoam, prefabricated vertical drains, geosynthetic encased-granular columns and mechanical densification through sand columns. This book is a valuable reference for researchers and practicing engineers alike.
