Instrument Introduction: This device can automatically complete solutions of different concentrations (water, brine, de icing solution),The volume expansion rate and solution pressure generated by sulfate solution, de icing salt solution, etc. under different temperature conditions. For freeze-thaw conditions, the freezing pressure and freezing expansion rate of concrete solutions at different saturation levels can be measured to study the freeze-thaw failure mechanism and salt freezing failure mechanism of concrete; For the condition of alternating dry and wet cooling, the salt crystallization pressure and crystallization expansion rate of sulfate and other solutions can be measured to study the physical salt crystallization failure mechanism of concrete
