摘要

This paper refers to aggregates and concrete primarily in the state of Iowa. It will note how some aggregates and concrete have both been long lived and short lived and how testing has changed to improve performance. It will also note what Iowa is doing to resolve recent problems. Although Iowa is the source of the information, many other areas of the country will have similar situations.
