Spe          Description





               Workshop Description


The purpose of the workshop is to bring attendees up-to-date with the latest information on the use of coal combustion products in concrete and other construction materials.  The program will include presentations showing important technical, environmental, and economic advantages of using coal ash 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.  The program will cover basic information, application case histories, as well as the latest developments in the utilization of coal ash from power plants in concrete, concrete products, and other construction materials.  Knowledgeable professionals engaged in specifying, approving, marketing, and using these materials will present state-of-the-art information. Handout materials will be provided.
