“…In light of these aspects, UHPC has received attention from builders who strive to develop slenderer structures, especially in bridges, to provide cost-effective construction. Therefore, UHPC has been extensively used in various structural members (e.g., precast girders, deck (infill) connections, railway slab systems, tiny elements, deck sheets, permanent formwork, and functionally categorized materials) for road and walkway bridges [16][17][18][19][20][21][22].…”

“…The bond integrity of UHPFRC to normal strength concrete (NSC) should be assessed to determine the strength of the composite system. Finally, the thickness of a UHPFRC overlay must be selected to lower the structure's dead load while retaining the bond interface's integrity [19]. If the repair is to endure all of the strains generated by forces such as volume changes, chemical and electrochemical effects, the repair material's compatibility with the current substrate is critical.…”

“…Los cambios de humedad en la CS de la losa de concreto generan contracción en la CS y dilatación en la CI (Vandenbossche, 2001). La deformación causada por cargas térmicas y retracción depende del coeficiente de expansión térmica del material, el cual se define como la expansión o dilatación del material debido a un diferencial de temperatura (Shann, 2012). Dicha condición de diferencial de temperatura entre las caras de la losa de concreto resulta en un levantamiento de los bordes o sección media, que ocasiona pérdida de apoyo con la base y una alta concentración de esfuerzos en el material (Math, Sheregar & Kavitha, 2015).…”

“…Una nueva alternativa de construcción de estructuras de pavimentos con concretos hidráulicos, es el uso de concretos de ultra alto desempeño (UHPC), por sus siglas en inglés Ultra High Performance Concrete, que según (Abdulkareem, Fraj, Bouasker & Khelidj, 2018), es un material dúctil de alta resistencia con una matriz densa y homogénea, formulado mediante la combinación de materiales cementantes, agregados finos, aditivos reductores de agua y fibras de acero u orgánicas (Perry, 2001), presentando una relación agua/cemento (A/C) inferior a 0.25 (Graybeal, 2011), con características mecánicas y de durabilidad superiores a un concreto convencional. El rango de resistencias a compresión puede variar entre 110 MPa (Wu, Shi, He & Wang, 2017) hasta 227.53 MPa (Shann, 2012) dependiendo de las condiciones de curado. Los menores valores de resistencia a compresión fueron obtenidos con técnicas de curado ambiente y para mayores valores fueron obtenidos con técnicas de curado térmico o con vapor (Chen, Gao & Ren, 2018).…”
