Reinforced concrete typically is cast to precise specifications, with little excess, reducing waste. Any generated waste can be recycled for another use. Its high-strength capabilities can minimize the number of …

Recycling and Reutilization of Waste Carbon Fiber Reinforced …

Faneca et al. reinforced high-strength concrete with waste carbon fiber bundles and CFRP sheets, and the results indicated that both carbon fibers and CFRP sheets reduced the workability of concrete and introduced more porosity. When the carbon fiber bundle content was in the range of 0.2% to 0.8%, the resistivity values ranged from …

2.2 Concrete Mix-Design. All the mixtures were designed by the Compressible Packing Model (CPM) [], with the software BetonLab Pro 3, considering the individual properties of each material and the maximum packing density of each mixture.An individual mix design was performed for each mixture, instead of just replacing the …

Recycling of Reinforced Glass Fibers Waste: Current Status

Abstract. In this paper, a review of the current status and future perspectives for reinforced glass fiber waste is undertaken, as well as an evaluation of the management hierarchy for these end-of-life materials. Waste levels are expected to increase in the coming years, but an improvement of collection routes is still necessary.
