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 ...

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 ...

Durability of Ultra-High-Performance Concrete
SP-261: 10th ACI International Conference on Recent Advances in Concrete Technology and Sustainability Issues, 2009This paper describes how ultra-high-performance concrete (UHPC) has gained more interest in the concrete construction industry in recent years due to the expected high durability of UHPC, as well as extended architectural opportunities. Compared to normal concrete it is possible to build filigree and lighter structures with ultra-high-performance ...

Aggregate Segregation of Ultra-High Performance Concrete
Key Engineering Materials, 2018This article deals with the aggregate segregation of ultra-high performance concrete. The main objective of this research was to determine which aspects of the design most affect segregation. It was studied the change of grading curve, water/powder ratio and consistency.

Micromechanical Homogenization of Ultra-High Performance Concrete
Applied Mechanics and Materials, 2016Mechanical properties and durability of Ultra-High Performance Concretes (UHPC) are closely associated with composition and microstructure of tested samples. In this work, determination of effective elastic properties of UHPC composite was performed for a representative volume element using combination of microstructural investigations (scanning ...
