Frost-Resisting Property of Bridge Concrete in Alpine Frigid Region

Abstract:

Supported by the Guozigou-bridge, the paper studied the Frost-resisting property of bridge concrete in alpine frigid region. Researched the effect of water-binder ratio, fly-ash content, water consumption and air-entraining agent consumption, and reveals the impact mechanism of frost-resisting property of bridge concrete in alpine frigid region. Analyzed the influence rule of frost-resisting property and showed reference value of concrete's ingredient rate in alpine frigid region. The result showed that low water-binder ratio and water consumption can effectively improve the deicer-frost resistance of concrete and the influence of water consumption is more significant. Best air content between 4.5% ~ 4.5%.
