Abstract
At the concentration recommended by the AEA manufacturer for use in concrete, two of the AEAs show no reduction in surface tension when exposed to a synthetic pore solution, but show strong interaction with Ca2Â + ions. This suggests that some AEAs rely more on surface tension reduction to stabilize bubbles and others rely primarily on calcium interaction. AEAs that self-associate more easily (and interact with calcium more strongly) offer better frost protection for mortars at lower AEA concentrations, which is the focus of a future publication.
