This study aimed to investigate the strength and permeability properties of binary ternary systems for producing concrete mixes with a cure time 7, 28, 90, 180 days under high ambient temperatures (about 35–45 °C). The key variables were silica fume (SF) fly ash (FA) water-to-binder ratio (0.18 0.55) needed cementitious normal ultra-high-performance (UHPC). tests conducted BS 1881 ASTM C 1202. ...

Numerical investigations on the performance of ultra-high concrete (UHPC) subjected to projectile impacts have attracted extensive attention, but there are still deficiencies in accuracy and computational efficiency related simulation methods. To make up for these deficiencies, a mesoscale equivalent model UHPC is developed simulate response under impacts. In this model, an treatment conducted ...

El hormigón de ultra-alto desempeño (UHPC) es un material compuesto con una notable capacidad autocompactación y alta resistencia a la compresión. Actualmente, construcción prefabricados en UHPC, debido sus propiedades excepcionales, considerada como opción interesante los proyectos ingeniería civil. desarrollo métodos prácticos confiables para el diseño conexiones pernos elementos UHPC ha sido...

As a high-quality building material exhibiting excellent toughness and durability, ultrahigh-performance concrete (UHPC) is increasingly being used in the construction industry as reinforcement. During reinforcement of existing structures with UHPC, their interface weakest part structure. Interface bonding ensures operation two types materials together. However, studies rarely report UHPC–norma...

Construction material sustainability and waste reuse have emerged as significant environmental issues. Concrete is widely used in the building engineering fields. Ultra-high performance concrete (UHPC), which has remarkably high mechanical properties, become one of most common varieties recent years. As a result, substantial amounts Portland cement (PC) are frequently used, raising initial cost...
