Utility of Ultrasonic Pulse Velocity for Estimating the Overall Mechanical Behavior of Recycled Aggregate Self-Compacting Concrete

Ultrasonic pulse velocity (UPV) is a non-destructive measurement technique with which the quality of any concrete element can be evaluated. It provides information on health and for assessing need repair in straightforward manner. In this paper, relationship studied between UPV readings mechanical behavior self-compacting (SCC) containing coarse, fine, and/or powdery RA. To do so, correlations simple- multiple-regression relationships compressive strength, modulus elasticity, splitting tensile flexural nine SCC mixes were assessed. The showed that property was fundamentally monotonic. inverse square-root model therefore best-fitting simple-regression all properties, although bending-tensile-behavior-related properties (splitting strength strength) estimation accuracy much lower than compressive-behavior-related (compressive elasticity). Linear-combination models related to bending-tensile had minimal influence value, their introduction resulted decreased accuracy. Thus, best fits those linked readings. This enables elasticity when are known deviation less ±20% 87% reported other studies available literature.
