This report formalizes the information provided to the contract monitor during the period of the contract. The contract involved the performance of measurements on specimens identified by label only (blind study). Cooling curves have been determined for nine complex salts for approximately 50% saturated solutions, and for two of the salts (DOT4 #13 and DOT4 #15) at a number of concentrations, expressed as salt/water ratio by weight, from 0.05 up to approximately 0.57. From these curves, the portion of the phase diagram for the solution/pure ice region was constructed. The results indicate the quality of the data and the efficacy of the method for determining this portion of the phase diagram.
The use and application of salt, sand and related mixtures and derivatives have proved to be highly effective for removing or controlling the developm...
