CONCRETE DETERIORATION ASSOCIATED WITH ONE GEOLOGIC SOURCE OF THE COARSE AGGREGATE WAS RECOGNIZED IN IOWA IN THE EARLY 1930S IN PAVEMENT LESS THAN 10 YEARS OLD. SINCE THEN, OBSER- VATIONS INDICATE THAT IN SOME OTHER CASES OF DETERIORATION THERE APPEARS TO BE A RELATION BETWEEN THE CONCRETE DURABILITY AND THE GEOLOGIC SOURCE OF THE COARSE AGGREGATE. ONE OF THE BASIC RESEARCH PROGRAMS OF THE IOWA STATE HIGHWAY COMMISSION FOR MORE THAN 20 YEARS HAS BEEN A STUDY OF THE BEHAVIOR OF CONCRETE MADE WITH AGGREGATES FROM DIFFERENT SOURCES. THE PROGRAM INCLUDES A STUDY OF THE PHYSICAL, CHEMICAL, AND GEOLOGIC PROPERTIES OF VARIOUS COARSE AGGREGATES AND OF THE PROPERTIES OF THE CONCRETE CONTAINING THESE AGGREGATES. THE PURPOSE OF THIS STUDY IS TO RELATE THESE CHARACTERISTICS TO THE BEHAVIOR OF THE CONCRETE IN SERVICE, AND THUS DEVELOP BETTER METHODS FOR DETERMINING THE PROBABLE PERFORMANCE OF PROPOSED MATERIALS. SEVERAL SELECTED CASE HISTORIES ARE REPORTED TO ILLUSTRATE THE VARIOUS ASPECTS OF THE PROBLEM AND THE METHODS USED TO RELATE THE CHARACTERISTICS OF COARSE AGGREGATE TO CONCRETE DURABILITY.
