May 1-2, 2008, DoubleTree Hotel Milwaukee City Center, Milwaukee, WI


Workshop Description

The purpose of the workshop is to bring to attendees the latest information available regarding LEED ratings established by USGBC and how to increase this rating with the use of coal combustion products and other recyclable materials in green construction. The program will include presentations showing important technical, energy, environmental, and economic advantages of using coal ash and other recyclable materials in ordinary, everyday construction applications. The workshop should be of interest to those associated with the construction industry, including design and materials engineers; architects; engineering technicians; engineers working in governmental agencies, industry, and private practice; engineering faculty and students; as well as ready-mixed concrete producers, concrete products manufacturers, and concrete contractors. The workshop will also provide significant help to people from utilities and other industries producing coal ash and other recyclable materials. The program will cover basic information, application case histories, as well as the latest developments in increasing LEED rating. Knowledgeable professionals engaged in specifying, approving, marketing, and using these materials will present state-of-the-art information. Handout materials will be provided.
