Abstract:
The elastic response of concrete to static, resonance, and pulse velocity tests is discussed. Because of the wide variations in static testing techniques and the heterogeneity of concrete, the results of Young’s modulus calculated from the three methods do not necessarily agree. The pulse velocity method has advantages over the other two in that testing is not confined to regularly-shaped laboratory specimens, and results are free from inelastic effects. The method, however, has severe limitations: it is so affected by the heterogeneity of concrete that calculations of Young’s modulus are discouraged, and it is not sensitive to small changes in the paste component of concrete.
