Engineering Properties of SCC for Airfield Concrete Pavements

Improvements on the performance and durability aspects of airfield concrete pavements are very crucial issue for operational and safety. In this regard, self consolidating concrete (SCC) mixtures proposed for this means and their engineering properties were assessed. The effects of (1) w/c ratio, (2) cement content, (3) and air-entrancement agent are designated to be assessed from the aspects of rheological, mechanical and durability properties. The results confirmed the effectiveness of air-entrained SCC mixtures for freeze-and-thaw actions. Moreover it was found that the w/c ratio and cement content could be useful in this regard.
