Ultra-high performance concrete
2008ABSTRACT: The main advantage of DUCON (DUctile CONcrete), a patented 3-D micro-reinforced, selfcompacting Ultra High Performance Concrete, is its ductility in combination with high compressive and flexural strength. This paper describes the properties and recent applications of DUCON.

Basic and Drying Creep of Ultra-High Performance Concrete
SSRN Electronic Journal, 2022Published online: 03 Apr 2023. OnlinePubl ; Experimental observations of the creep behaviour of ultra-high performance concrete (UHPC) are limited, with existing studies all performed on material designs including fibres. This limits the understanding of the underlying behaviour of the cementitious material, including the relative contributions of ...

Fiber orientation effects on ultra-high performance concrete formed by 3D printing
, 2021Despite the growing interest in 3D concrete printing, its current progress is limited by reinforcing methods. Inclusion of steel fibers is a potential reinforcing solution; however, the effect of printing process on orientation of the fibers is still ...

Rehydration of Ultra High Performance Concrete
Advanced Materials Research, 2014Ultra High Performance Concrete (UHPC) and High Strength Concrete (USC) are because of the high density of their matrices very susceptible to spalling during fire exposure. By aid of a heat treatment with maximum temperatures of about 450°C a network of capillaries and micro cracks could be formed, which leads like a porous medium to a relief of water ...
