Abstract:

This report documents the work performed under Contract No. 3213 to the South Dakota Department of Transportation. The deicing materials developed by S.D. DOT have been evaluated together with their component materials. It has been found that the deicer designated SD2 is effective in greatly reducing the bond strength of ice to Portland Cement Concrete which has been treated with the material. Also, it is suggested that the effectiveness of SD2 is a result of a synergism between its components. An apparatus has been developed which can monitor the cooling curve of solutions through their freezing points. Experiments in this device have shown that SD2 freezes into a disordered solid, as does one of its components, sodium glycolate. It is concluded that there could be very significant benefits from a continuation of this work, not only to determine whether the properties of SD2 can be attributed to a synergistic mechanism, but also to seek a fundamental understanding which, in time, may allow the development of equally effective, but perhaps less expensive, deicers.
