Development of Ultra-Rapid Setting Construction Materials for Extremely Cold Regions Using Magnesia-Phosphate Cement

Abstract:

Because ordinary concrete cannot be hardened well under sub-zero temperatures, anti-freeze agents are typically added to prevent the frost damage and to ensure the proper hardening of concrete. With the advantage of a rapid exothermic reaction property, jet set concrete may be used as a cold weather concrete because it can reach the required strength before being damaged by cold weather. Recent studies are reported that magnesia-phosphate cement can be hardened very quickly and hydrated even in low temperature, which can be used as an alternative of severe cold weather concrete in arctic regions. This study developed the magnesia-phosphate cement that can be used in severe cold regions and suggested an appropriate mixture design from the experimental results.
