Oklahoma material sources for Portland cement concrete (OK-96-03)

Abstract

Traditionally, Oklahoma Department of Transportation (ODOT) specifications and the high quality of the limestones and shales used for the production of Portland cement concrete (PCC) materials have prevented any significant alkali-silica reactions (ASR) on their structures or pavements. The materials that could affect ASR include: Portland cement, fly ash, coarse aggregate, fine aggregate, and water. This report contains location information for the mineral ingredients used in Portland cement concrete in ODOT pavements and structures.
