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 ...

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 ...

Tensile characteristics of ultra-high-performance concrete
Magazine of Concrete Research, 2018In this study, the tensile properties of ultra-high-performance concrete (UHPC) with a large number of short steel fibres were investigated. In addition, the effects of fibre length, mono and hybrid fibres were studied in order to compare the performance of different UHPCs.

Autoclaving of ultra‐high performance concrete (UHPC)
ce/papers, 2018AbstractBy the combination of an optimized granulometry, a reduced water–cement ratio and the use of superplasticizers ultra‐high performance concrete achieves a compressive strength of over 150 N/mm2 and a high resistance regarding acids and water‐soluble salts.

Shear behavior of ultra-high performance concrete
Construction and Building Materials, 2018Abstract The application of ultra-high performance concrete (UHPC) as an alternative to conventional/normal concrete (NC) has grown rapidly in recent years. However, there is limited knowledge on its shear behavior, which is essential for developing design guidelines for structural applications.

Ultra-high performance concrete – properties and technology
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2013Abstract The paper deals with information concerning properties and technology of a new generation cementitious composite i.e. Ultra-High Performance Concrete. High performance here means both high strength and high durability under the influence of environmental factors.
