Report identifies effect of ingredients on air-void stability
Various investigations throughout North America have revealed that unusually severe winters have caused an inordinate number of reported cases of scaling in concrete. A recent report from the Portland Cement Association, Cement-Alkali Level as it Affects Air-Void Stability, Freeze-Thaw Resistance, and Deicer Scaling Resistance of Concrete (RD128), investigates potential contributors to deterioration in concrete.

This investigation was designed to evaluate the stability of the air-void system, as well as resistance to freezing and thawing and deicer chemicals in concretes containing various generic types of air-entraining admixtures and differing levels of alkalis in cement.

To obtain the report, call (800) 868-6733 or visit www.cement.org.
