Influence of aircraft deicer on apron cement concrete

In order to explore the cause and mechanism of apron cement concrete scaling, deicer component analysis, concrete specimen deicer soaking test and phase analyzing were carried out. It is found that there is no chemical reaction between deicer and cement concrete, water pressure, penetration pressure and vapor pressure variation are increased in concrete after deicer infiltration. The results show that scaling is caused by the freeze thawing cycle, infiltration of deicer deteriorates scaling. The scaling preventive treatments, such as reducing the volume of deicer, limiting its application area and contact time to concrete, and freeze proof ability of concrete could be considered.
