Abstract:
The chemical interaction of certain rocks and minerals of aggregate with high-alkali portland cements is known to have caused serious distress of concrete structures in California, Oregon, Idaho, Arizona, Nebraska, Kansas, Washington, Wyoming, Virginia, and New York. Similar distress will undoubtedly be discovered in other states. Microscopic, microchemical and physical-chemical studies of concrete have revealed the detailed characteristics of the deterioration, and make possible the distinction of this type of deterioration from others.
