Welcome to CE488 Environmental Geotechnics Lecture #7 Dept. of Civil Engineering IIT Bombay
CURRENT RESEARCH FOCUS • Synthesis and Characterization of Fly Ash based Zeolites • Utilization of Industrial By-products – Waste to Energy – Zeolites in Agri- & Aqua-culture • Characterization of Soil for Agricultural Applications • Nano-sensors for Soil Moisture Determination • Sustainable Construction Materials (Artificial Sands) – Nano-Micro Materials • Swelling/Shrinkage and Cracking Characteristics of Soils • Characterization of Gas Hydrate bearing Sediments • Bio-Geotechnology • Modeling Heat Migration in Geomaterials
Gas Hydrates • Host and Guest Molecules • No bonding between hosts and guests. • Guests are gases – primarily methane • Amount of gas entrapped is huge
Hydrates Bearing Sediments • Stability Conditions Overlying Sediment Layer (Geothermal gradient) • Hydrate Stability Zone Intermediate Sediment Layer • Free Gas Zone
