Title: Compressive Strength and Ultrasonic Pulse Velocity Relationships for Concrete in Columns
Author(s): M. F. Kaplan
Publication: Journal Proceedings
Appears on pages(s): 675-688
Keywords: no keywords
Abstract:Reports an investigation to determine to what extent compressive strength and pulse velocity tests indicate the variability and compressive strength of concrete as it exists in a series of columns. Concrete cubes site cured under the same atmospheric conditions as the concrete columns had a compressive strength averaging 10 percent lower than the strength of the concrete in the columns. Concrete cubes continuously cured under water averaged 23 per-cent higher strength than the concrete in the columns. When the pulse velocity in the columns was measured, the corresponding compressive strength as obtained from the pulse velocity-strength relationship for the site cubes averaged 18 percent lower than the actual strength of the concrete in the columns. The compressive strength obtained from the relationship for cubes continuously cured under water averaged 29 percent lower than the actual strength. Pulse velocity values for the concrete in the columns gave a better indication of the variation in strength quality of the concrete than did compressive strength results on concrete cubes.
