Evaluation of freeze-thaw damage in concrete by one-sided stress wave velocity measurement technique
Abstract. A recently developed one-sided stress wave velocity measurement technique is used to evaluate freeze-thaw damage in concrete. The freeze-thaw damage was induced in a 400x350x100 mm concrete specimen in accordance with ASTM C666 using a commercial testing apparatus. A cycle consisted of a variation of the temperature from -14 deg C to 4 deg C. A cycle took 4-5 hours with approximately equal times devoted to freezing-thawing. The measurement oflongitudinal and surface wave velocities based on the one-sided stress wave velocity measurement technique was made every 5 freeze-thaw cycle. Experimental results showed that damage induced by freeze-thaw cycles caused a larger change in longitudinal wave velocity as measured by the one-sided stress wave velocity measurement technique than that in Rayleigh wave velocity. In addition, the new method for one-sided stress wave velocity measurement was more effective in evaluating freeze-thaw damage in concrete than the conventional ultrasonic through transmission technique.
