Reliability of the ultrasonic pulse velocity for analysis and comparison of the compression strength of conventional concrete with addition of steel fiber and polypropylene

The research aimed to evaluate the reliability of the ultrasonic pulse velocity method. The resistance of the concrete established by correlation curves by the ultrasonic pulse velocity and sclerometric index tests was estimated, developing simple and multiple correlation curves by the SonReb method...

The resistance of the concrete established by correlation curves by the ultrasonic pulse velocity and sclerometric index tests was estimated, developing simple and multiple correlation curves by the SonReb methodology. Using conventional concrete with the addition of 5% steel fibers and 0,21% polypropylene, with a mix design f´c = 21MPa. Seventy two 150 x 300mm concrete cylinders were prepared. On days 7, 14, 21, and 28, tests for compressive strength, sclerometric index, and ultrasonic pulse velocity were performed. In conclusion, the ultrasonic pulse velocity measurements revealed a good categorization of concrete quality as excellent and a strong dependency correlation. In general, the percentage of error presented by the analytical equations remains within +-10% La investigación tuvo como objetivo evaluar la confiabilidad del método de la velocidad del pulso ultrasónico. Se estimó la resistencia del concreto establecido por curvas de correlación por las pruebas de Velocidad de Pulso Ultrasónico e Índice Esclerométrico, desarrollándose curvas de correlación simple y múltiple por la metodología de SonReb. Utilizando un concreto convencional con la adición de fibras de acero 5% y polipropileno 0,21%, con un diseño de mezcla f´c = 21MPa. Se prepararon setenta y dos cilindros de concreto de 150 x 300mm. En los días 7, 14, 21 y 28, se realizaron pruebas de resistencia a la compresión, índice esclerométrico y velocidad del pulso ultrasónico. En conclusión, las mediciones de la velocidad de pulsos ultrasónicos revelaron una buena categorización de calidad de los concretos como excelente y una correlación de dependencia fuerte. En general, el porcentaje de error que presentan las ecuaciones analíticas se mantienen dentro del +-10% Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2023-01-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/4380 10.51372/gacetatecnica241.2 Gaceta Técnica; Vol. 24 No. 1 (2023): January-June; 2-21 Gaceta Técnica; Vol. 24 Núm. 1 (2023): Enero-Junio; 2-21 Gaceta Técnica; v. 24 n. 1 (2023): January-June; 2-21 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/4380/2801 https://revistas.uclave.org/index.php/gt/article/view/4380/2810 https://revistas.uclave.org/index.php/gt/article/view/4380/2811 https://creativecommons.org/licenses/by-nc-sa/4.0
