WORLD OF COAL ASH (WOCA) - May 4-7, 2009 in Lexington, Kentucky
WOCA Shortcourse
The Science of Ash Utilization
This short course will cover basic information about the science and technology of coal combustion by-products. It will be taught by leading experts from academia and industry in two parallel tracks, offering more choices for students. This year's short course will feature an expanded sessions on the geotechnical characteristics of ash in landfill and impoundments and as a material for engineering road base and structural fill as well as a session on green cement technology (non Portland cement). These sessions will be taught by leading experts in the field.
