INVESTIGATING THE FEASIBILITY OF USING RECYCLED FIBRES INSTEAD OF INDUSTRIAL FIBRES IN SHOTCRETE

Rudarsko-geološko-naftni Zbornik
Shotcrete is one of the standard systems used in the tunnelling industry, including cement, sand, water, and additives. Adding fibres to shotcrete is a method to enhance its mechanical properties.

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.

A Statistical Model of Fibre Distribution in a Steel Fibre Reinforced Concrete [PDF]

Materials, 2021
The aim of the research was to create a model of steel fibre distribution in a Steel Fibre Reinforced Concrete space using statistical probability means. The model was created in order to better understand the behaviour of the composite under operating conditions.

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 ...

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 ...
