Abstract:
Polycarboxylate ether (PCE) high-range water-reducing admixtures were not fully commercialized in the North American concrete industry until the mid-1990s. Since then, PCE admixtures have been widely applied to dramatically extend the capabilities of concrete mixtures. This article reviews the diverse performance attributes of PCEs that have been demonstrated over the past 25 years as well as the opportunities they provide to meet current and future needs of the concrete construction industry.
