• 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

(Geothermal gradient)

• Hydrate Stability Zone
• Free Gas Zone
