As the modular industry expands, the most widely used building materials are primarily concrete, steel, and wood. However, the use of wood and steel is severely limited compared to concrete for reasons such as durability and economy. To overcome these shortcomings, we aimed to apply ultra-high-performance fiber-reinforced concrete (UHPFRC), which h...
Concrete structures in marine environments are prone to deterioration and damage due to chloride ion penetration, freezing and thawing, and chemical erosion. Ultra-high-performance concrete (UHPC) mixed with steel fibers has been proposed as a solution to enhance the durability and mechanical properties of concrete in marine environments. Although...
Recently, carbon materials with unique properties, such as high tensile strength and electrical conductivity, have been extensively investigated for the multi-functionalization of concrete. Previous studies mainly focused on improving the performance of normal-strength concrete using carbon nanomaterials, such as carbon nanotubes and graphene nanop...
Ultra-high-performance concrete (UHPC) is required to develop multifunctional concrete structures such as long-span bridges. During the construction of long-span bridges, girders exhibit significant differences in age because they use different curing days in the precast process. In this study, the performances of UHPC were compared when subjected...

... Above 0.80 % CNT, there was an increase in electrical conductivity [76,77]. Another study indicated that the UHPC's ER decreased modestly as the CNT content increased [95]. For these cases, it should be noted that the dosage of UHPC is generally different from ordinary concrete, with a lower w/c ratio and using other additions, such as fumed silica or silica powder. ...

... Este material, compuesto por agregados gruesos y finos, agua, cemento, y en ocasiones, aditivos para optimizar sus propiedades, enfrenta el desafío de cumplir con estándares de calidad elevados, particularmente en lo que respecta a sus propiedades mecánicas como la resistencia a la compresión y a la tracción (Zambrano, Alava, Ruiz, & Menéndez, 2022). Estas propiedades, cruciales para la integridad estructural y durabilidad del concreto, están intrínsecamente relacionadas con el proceso de curado al cual se somete el material después de su fraguado (Kwangmo, Kyongchul, Kyungtaek, & Gumsung, 2022). ...
