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.
Ireland: Ecocem has secured €4m in research funding as part of the European Innovation Council’s Pathfinder Challenges 2024 in order to optimise electric arc furnace (EAF) slag for low-carbon cement production. The four-year programme is funded by Horizon Europe and will explore ways to enhance EAF slag reactivity and its suitability as a supplementary cementitious material without compromising cement durability. The project was submitted to the Pathfinder Challenge 2 call: “Towards Cement and Concrete as a Carbon Sink.”
Corporate development executive director Eoin Condren said “For many years, we have been pioneering the use of a range of slags and cementitious materials to create scalable and durable low-carbon cement. Thanks to this grant, we will continue our groundbreaking work as the steel industry transitions to new manufacturing processes, delivering a viable solution for a new generation of waste from steel.”
UK: Tata Steel plans to install a new electric arc furnace (EAF) at its Port Talbot steel refinery in Wales. Modern Railways News has reported that the upgrade will generate an anticipated 3.5Mt/yr of additional rail freight. The furnace will produce 255,000t/yr of EAF carbon steel slag. Tata Steel reportedly expects to sell the slag for use in roadbuilding, mainly in South East England.
UK: Construction firm John Sisk & Son has successfully concluded its construction of part of the Wembley Park mixed development using concrete produced with Ecocem’s ACT alternative circular cement. The concrete met design specifications for all elements, while reducing embodied CO2 emissions by 70%. Construction Index News has reported that Capital Concrete and Creagh Concrete also participated in the project, which commanded €594,000 in Innovate UK funding.
