Ultra-high performance concrete reinforced with macro fibres recycled from waste GFRP composites

Case Studies in Construction Materials, 2023
Ultra-high-performance concrete (UHPC) is a promising cementitious composite to produce lightweight and high-performance structures. Steel fibres are an essential constituting material of UHPC to prevent the brittle failure of UHPC, but the high cost ...

Fibre orientation and distribution in steel fibre reinforced concrete

, 2023
The structural performance of steel fibre reinforced concrete (SFRC) composites, including ultra-high-performance concrete (UHPC), is sensitive to the orientation and distribution of fibres achieved during casting. Fibre distribution resulting from a concrete flow during casting is generally non-uniform, biased, and challenging to determine.

Recent advances in structural fibre-reinforced concrete focused on polyolefin-based macro-synthetic fibres

Materiales de Construccion, 2020
Fibre-reinforced concrete (FRC) allows reduction in, or substitution of, steel-bars to reinforce concrete and led to the commonly named structural FRC, with steel fibres being the most widespread.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Effect of steel fibres on concrete behavior in 2D and 3D simulations using lattice model

Archives of Mechanics, 2010
Quasi-static simulations of a concrete behaviour with steel fibres under uniaxial tension were carried out using a discrete irregular lattice model. Fibrous concrete was described at a meso-scale as a three-phase material composed of aggregate, cement ...
