Assessment of physical and mechanical properties of sawdust concrete using ultrasonic pulse velocity

This research aims to investigate the correlations between ultrasonic pulse velocit y (UPV) and physical (water absorption, void ratio and density) and mechanical (tensile and compressive strength, static and dynamic modulus of elasticity) properties of sawdust concrete in which sand was replaced by 0, 25, 50, 75 and 100% of Pinus elliottii Engelm sawdust, in volume. Results show that mechanical properties of sawdust concretes decreased, t he higher the percentage of wood . Higher values of density and mechanical properties of sawdust concretes a related to lower void ratio and water absorption. The use of UPV showed to be trustworthy to estimate quantitatively physical and mechanical properties of sawdust concretes.
