Abstract

The research project, HR-110, was begun in the fall of 1964 to further investigate the compositional and mechanical properties of some of the carbonate rocks used as aggregate in portland cement concrete. Samples were taken only from those portions of the quarries that are used as aggregate in portland cement concrete by the Iowa State Highway Commission except where designated by commission personnel for purposes of evaluation of potential aggregate sources. Where practical, the samples were taken from each bed recognized by the Highway Commission geologists, and in most instances, the thicker beds were sampled at the top, middle, and bottom to detect any lithologic changes that escaped megascopic observation.
