This investigation (Dorheim, 1950) was made m an effort to identify mineralogical or textural characteristics of limestones that might affect the durability of concrete. The Iowa State Highway Commission has found that when certain limestones were used as coarse aggregate in concrete, that concrete gave excellent service in paving. Other limestones that responded to standard testing procedures in a similar manner, gave very poor results when used in concrete paving.
