“…For example, Ghafari et al used 950 kg/m 3 cement and 250 kg/m 3 SF to produce UHPC [4]. Yu et al produced UHPC with 620 kg/m 3 cement to obtain a compressive strength of 100 MPa [2]. Aldahdooh et al utilised 638 kg/m 3 cement to design an UHPC with 120 MPa of compressive strength [5].…”

Ultra-high performance concrete (UHPC) has superior mechanical properties and durability to normal strength concrete. However, the high amount of cement, high environmental impact, and initial cost are regarded as disadvantages, restricting its wider application. Incorporation of supplementary cementitious materials (SCMs) in UHPC is an e ective way to reduce the amount of cement needed while contributing to the sustainability and cost. is paper investigates the mechanical properties and microstructure of UHPC containing y ash (FA) and silica fume (SF) with the aim of contributing to this issue. e results indicate that, on the basis of 30% FA replacement, the incorporation of 10% and 20% SF showed equivalent or higher mechanical properties compared to the reference samples. e microstructure and pore volume of the UHPCs were also examined. Furthermore, to minimise the experimental workload of future studies, a prediction model is developed to predict the compressive strength of the UHPC using arti cial neural networks (ANNs). e results indicate that the developed ANN model has high accuracy and can be used for the prediction of the compressive strength of UHPC with these SCMs.

“…Globally, the production of cement accounts for more than 5% of anthropogenic carbon dioxide emissions each year. As such, much attention has been paid to producing UHPC with less cement and a lower environmental impact while providing equivalent properties [2].…”

“…However, increased strengths have been accompanied by brittle failure, inevitably, which limited the application of high strength concrete in many structures. Developed ultra-high performance concrete (UHPC) with fibers has both higher strength and ductility through the incorporation of a large amount of fibers (Habel et al 2006;Yang et al 2009;Yu et al 2015). Attributing to the addition of fibers in cement-based materials, UHPC possesses an excellent strain-hardening, and the progressive multiple cracks are achieved rather than the brittle failure under applied loads conditions (Li and Maalej 1996;Li et al 2001;Park et al 2012).…”

Ultra high performance concrete (UHPC) with steel fibers not only possesses the higher compressive strength can be up to above 100MPa, but also has better tensile strength and ultimate strain because of the addition of steel fibers compared with ordinary concrete. However, the permeability behavior of UHPC is frequently ignored in the durability dsign or repair, especially for that with a mass of cracks after suffering short-lived vibration, shock or explosion. This paper is developed to investigate the permeability behavior of UHPC after suffering tensile and compressive loadings, and the water as well as chloride permeability are determined. The results show applied tensile and compressive loadings increase the water and chloride permeability of UHPC. Particularly for the UHPC after suffering high loading damage, the increase of permeability becomes more obvious. Self-healing treatment is also applied to the UHPC with loading damage, and the permeability resistance of UHPC is improved by the treatment of self-healing, which provides an effective method to repair the UHPC with loading damage. In addition, the relation between permeability behavior and applied loads or cracks development are established in this paper, which can be used to evaluate the permeability behavior of UHPC suffered loading damage.

“…As SFRC has become more popular in building and civil construction, some constitutive models, design approaches and tests have been developed [6][7][8][9][10][11][12]. Hence, the challenges of FRC are now based on the best exploitation of the materials and the optimization of the fibers and matrices in order to produce the most suitable composite material for a specific purpose [13].…”

Abstract:The increase in the use of polyolefin fiber-reinforced concrete (PFRC) is in contrast to the limited amount of published research about its fracture behavior. This study assesses the main mechanical and fracture properties of PFRC by using conventional and self-compacting concrete with various dosages. The results highlight the significant performance of PFRC and revealed that improving its residual strength for small deformations would enhance its use for structural purposes. For that matter, a combination of polyolefin and steel-hooked fibers was used, improving the results and showing synergies between the two types of fibers that could be exploited for infrastructure applications. The significance of this research is, in addition to the characterization of PFRC, the optimum selection and definition of the proportions and characteristics of the types of fibers chosen for the combination. The results proved that, by combining hooked-steel fibers and macro-polyolefin fibers, it is possible to preserve the high-performance fresh properties and obtain a reliable behavior with synergies in the fracture results. The latter provides an efficient use of the materials, as well as a better mechanical behavior in both service and failure states.
