Track No. 6: Geoenvironmental Engineering

Session: Advances in Sustainable Barrier Materials

Description of the Topic
Sustainable materials are recently developed to replace or enhance the performance of clayey and cement/bentonite Hydraulic Barriers. The objective in developing innovative barrier materials is to produce a barrier that is more efficient and/or less costly than existing barriers.

The industry and construction sector face today an increasing problem of how to dispose of its voluminous residues. Several types of alternative materials, such as clay mixed with polymers or ashes or dredged soil, have been recently proposed to replace or amend conventional barrier materials.

Some of the residues used are constituted of large amounts of:

- organic molecules, polymers (by-products of food industry),
- ashes and slag (generated from incineration and melting),
- excavated and dredged soil (from maintenance, construction and remedial works),
- phosphogypsum (by-product of processing phosphate),
- sludges (from chemical, paper and glass industry),
- etc.
