Losas de HRFA, Tomografía computada, Orientación y distribución de las fibrasResumen
El desempeño mecánico de los materiales fibrados, como el Hormigón Reforzado con Fibras de Acero depende (HRFA), depende principalmente de la orientación y distribución del refuerzo de fibras dentro de la masa cementicia. Este hecho despierta la necesidad de continuar con el estudio de este fenómeno para así comprender mejor el comportamiento del material maximizando su rendimiento. En este trabajo se lleva a cabo un estudio de la configuración espacial de las fibras de acero en elementos losa a partir de la visualización y análisis de imágenes obtenidas mediante tomografía computada. Luego, a partir del uso de esta tecnología junto con algoritmos de segmentación y software de reconstrucción de imágenes 3D, se obtienen perfiles de orientación y distribución de manera detallada. Las imágenes muestran una distribución homogénea sin detectarse zonas significativas de mayor o menor concentración de fibras. Respecto a la orientación, se obtiene una marcada predominancia de la posición de las fibras en un plano paralelo al eje de la losa.
