Abstract:
Presents results of a 2-year study of the increase in chemical resistance provided by adding microsilica to concrete. Concretes containing varying dosages of microsilica were exposed to alternating wet-dry cycles of several common organic and inorganic acids. The addition of microsilica was found to increase time to failure in all the solutions tested, but the magnitude of increase varied widely for different acids.
