| description | The noninvasive
technique of ultrasonic pulse rate (UPV) is increasingly used in the evaluation
of the quality of concrete, providing information about the integrity of
structures and preventing possible disasters. Therefore, for its direct
application, it is necessary to have a prior correlation between the
noninvasive UPV technique and the invasive uniaxial compression resistance
(UCS) assay. While correlations have been determined by various authors, each
has been given specific conditions and guidelines by the authors because there
is no standardized way to perform the correlations. Rather, there are only
experimental tests that have generated experimental correlations—both linear
and logarithmic—with different graphic shapes. Therefore, this research aims,
first, to validate the aforementioned relationship, which allows the
compressure resistance of concrete (f'c) to be determined for a given design of
concrete mixtures following the American Concrete Institute (ACI. 211.1.).
Second, it aims to determine the most accurate trend and the possibly correct
form of the correlation plot between the UPV and UCS. In the first instance, 15
plain concrete specimens were designed with an f’c of 28 MPa, whose dosage was
carried out following the method of ACI. 211.1. Then, UPV and UCS tests were
performed according to regulations in the first 28 days of curing the
specimens. Finally, a logarithmic correlation was obtained between the UPV
values and the values of the invasive tests for the UCS of concrete. A
graphical analysis with some existing correlations of other investigations was
then performed, and a similarity in the logarithmic tendency, with a
coefficient of determination greater than that of the linear trend, was
observed. |
