Abstract:
Primarily, this study was undertaken to determine whether any relation-ship exists between the composition, fineness, and conditions of manufacture of the test cements and the ability of the concrete in which the.y were used to resist disintegration when subjected to external influences such as water, sul-fate solutions, temperature changes, and highway traffic with or without appli-cation of salts for ice removal. Most of the test structures have now been exposed to weathering for ten years and this report presents the most important facts regarding the cements and their performance. No consistent relation was found between the composition and fineness of the cements and the behavior of concrete exposed to freezing and thawing. Differences in manufacture did not, significantly affect the duiability of the concrete. Resistance to sulfate attack was increased by reduction of the potential CSA content of the cement. Substantiating otherstudies, the evidence was strong that air entrainment greatly increases the ability of concrete to endure freezing and thawing without deterioration and was found to be particularly effective in preventing scaling when chlorides are used for ice control on concrete pavements.
