Freeze Thaw

Freeze thaw testing measures the resistance of concrete to deterioration caused by repeated cycles of freezing and thawing water.  The Freeze Thaw Cabinet system tests up to eighteen 3″ x 4″ x 16″ concrete specimens simultaneously with one being a control.  The Sonometer works with the cabinet to determine changes in resonant frequency of concrete subjected to alternate cycles. Freezing and thawing closely follows the parameters of the Portland Cement Association.  The E-Meter finds the resonant frequencies of the three modes of vibration and is the only method of calculating the following material parameters non-destructively:  Youngs modulus of elasticity, modulus of rigidity and Poissons ratio damping constant.
