Installation and methodology for determining the temperature of the onset of freezing of water in soils, rocks and pore solutions
Abstract
The article presents a modernized installation and a methodology for the determining of the temperature of the onset of the freezing of water in soils, rocks and pore solutions. In order to provide independent from the temperature in the freezing chamber regulation of the samples cooling intensity, the working chamber of the unit is modernized by supplementing it with a security heater placed on the body of the device and a control differential thermocouple embedded in the thermal insulation layer of the device. This makes it possible by regulating the heater supply voltage to reduce the temperature difference in the insulation layer and thereby provide the slowdown of cooling during the period of the probable onset of the samples freezing under study, which will provide more accurate determination of the onset temperature of freezing. The installation can be used to express determination of the freezing onset temperature of water in soils, rocks and pore solutions.
