US: Willbee Transit Mix has replaced its existing Jadair International Redi-Wash washout with the latest model from the same supplier. The newly installed system reclaims concrete and clarifies water in a self-contained, closed-loop unit, discharging sand and stone for complete recovery. It allows truck drivers to perform washouts by pressing a button.
US: A team of researchers has outlined a new method for recycling carbonated concrete wash water in a patent application. News Rx has reported that the method involves adding concrete wash water along with concrete ingredients and mix water into a mixer. The carbonated concrete wash water may comprise 10 – 40% of total mix water. The inventors claim that the resulting concrete increased in strength by 5% compared with conventional ordinary Portland cement (OPC) concrete, and also reduced the required cement use by up to 5%.
UK: Recycling company Scott Bros has begun commissioning its new €1.18m, 480m³/day alternative concrete plant in Haverton Hill in Stockton-on-Tees, prior to full-scale launch in May 2025. The plant will produce concrete using its Activated Filter Cake (AFC) alternative binder, reducing its CO2 footprint by 25%. Scott Bros developed AFC in partnership with Teesside University from a clay by-product of its wash plants. The plant will use sand and gravel from recycled sources. Scott Bros invested a €720,000 grant from Innovate UK towards the project.
South Korea: Steel company Posco Group has partnered with seven South Korean cement and ready-mix concrete producers and five construction firms, along with the Korea Concrete Institute and the Research Institute of Industrial Science & Technology, to develop novel concretes from slag. The Korea Herald newspaper has reported that Posco Group will supply its slag for the development process.
The project aligns with Posco Group’s ‘super-gap’ future market-orientated innovation strategy.
