 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)
At the Geo-Frontiers 2011 conference, there will be a technical session on "Advances in Sustainable Barrier Materials." We invite abstract submissions for this intriguing new session under the Geoenvironmental Engineering track.
Abstracts may be submitted through the Geo-Frontiers 2011 website (http://www.geofrontiers2011.com) through 8 March 2010. I also welcome your session inquiries (contact information below).
Geo-Frontiers 2011 brings together the North American Geosynthetics Society (NAGS), the American Society of Civil Engineers (ASCE) Geo-Institute (GI) and the Industrial Fabrics Association International (IFAI). Current tracks include Soil/Rock Mechanics and Modeling; Geotechnical Testing and Site Characterization; Foundations and Ground Improvement; Slopes, Embankments, and Earth Retaining Structures; Geosynthetics; Geoenvironmental Engineering; Geo-Hazards (Earthquakes, Landslides, Erosions, Others); Transportation Materials and Pavements; and Other Geotechnical Related Issues.
The conference will be held 13-16 March 2011 in Dallas, Texas.
