- Abstract
- This is a progress report on the development of DURCON an expert system to give recommendations on the selection of constituents for durable concrete. Four major concrete deterioration problems will be covered when the DURCON system is completed; freeze-thaw, sulfate attack, corrosion of reinforcing steel, and cement-aggregate reactions. The factual knowledge base for DURCON is based on the American Concrete Institute Guide to Durable Concrete. Heuristic knowledge is being obtained from experts on the durability of concrete. The approach being taken in developing DURCON is discussed. Then a model expert system for concrete exposed to freeze-thaw conditions is described.
