Influence of Age in Concrete Structures by Means of Core Testing

Abstract

The structural test based on the correlation of results between Ultrasonic Velocity (V) and Pressure Resistance (R), obtained from samples extracted in structural elements of reinforced concrete serves as a tool for understanding the quality of the concretes. To analyze the influence of age, it has been used this method of correlation, confirming the better performance of structures aged less than 20 years. For older ages, it is statistically justified the need for intervention, repair – reinforcing based on the results of the test and results of the correlation ultrasonic velocity- compression on concrete testing cores.
