Implementación de ensayos no destructivos en hormigón y correlación entre ellos, esclerómetro y ultrasonido con hormigón, con dos diferentes equipos y diferentes dosificaciones.

Abstract

The estimation of the compressive strength of concrete is an important indicator of its quality, therefore non-destructive tests are very useful in estimating this factor and advantageous due to their rapid application and simplicity in their execution without affecting the structure and resistance of the material. However, the interpretation and treatment of data required a more complex analysis, considering the variables that affect the required results. This work focused on the application of non-destructive tests: sclerometer and ultrasound, for the estimation of the compressive strength of concrete, calculating a calibration curve of the sclerometer later to correlate it with the results of the ultrasound test and contrast the results obtained with the application of simple compression tests. The dosage of the materials for concrete of 24 MPa resistance was calculated and the casting of 30 type test specimens was carried out which were subjected to the different destructive and non-destructive tests mentioned above at the ages of 28, 56, and 90 days, in this way the correlation of the sclerometer and ultrasound was calculated, obtaining optimal results to finally determine that the characteristic in situ resistance of the concrete is 27.4 MPa for the sclerometer and 26.2 MPa for the ultrasound in contrast to the average value of the compressive strength of 29.6 MPa.
