Sweden: Researchers at the department of architecture and civil engineering at the Chalmers University of Technology in Gothenburg in Västra Götaland county are developing a technology to enable concrete to store energy in the manner of a rechargeable battery. The team has proposed a design based on cement mixed with short carbon fibres. The concrete is then fitted with a metal-coated carbon fibre mesh that forms the battery’s anode and cathode. The team says that a future product based on the technology would enable solar-powered roads and buildings to store their own energy. Additionally, the introduction of sensors to the system would enable full and constant monitoring of the condition of the structure.

Chief researcher Emma Zhang said, “Results from earlier studies investigating concrete battery technology showed very low performance, so we realised we had to think out of the box, to come up with another way to produce the electrode. This particular idea that we have developed – which is also rechargeable – has never been explored before. Now we have proof of concept at lab scale.”

Australia: James Hardie’s consolidated net sales increased by 12% year-on-year in the 2021 financial year to US$2.91bn from US$2.61bn in the 2020 financial year. Its adjusted earnings before interest, depreciation and taxation (EBIT) rose by 29% US$629m from US$487m. The producer recorded increased fibre cement sales in North America, by 12% to US$2.04bn from US$1.82bn, and in Asia Pacific, by 3% to US$496m from US$479m. The group’s Europe building products division’s sales rose by 5% to US$273m from US$261m.

Chief executive Jack Truong said, “I am proud of our globally integrated team’s ability to close out the fiscal year with a fourth quarter of exceptionally strong results. We have now delivered eight consecutive quarters of consistent profitable growth, including record financial results each of the past three quarters. Our performance in fiscal year 2021 marked a significant step change across multiple facets of our global company that allowed us to deliver this consistent profitable growth on an expanding global scale. Over the past 12 months, we were able to accelerate our strategy: firstly to unlock capacity and increase efficiency in our global manufacturing network through LEAN initiatives, and secondly to better integrate our supply chain with our customers, which collectively drove consistent market share gains in all three regions.”

Nigeria: Dangote Cement says that work is underway to increase its total cement production capacity in Nigeria by 4.5Mt/yr before September 2021. The Guardian newspaper has reported that plans consist of new lines at the company’s cement plants in Obajana, Kogi state, and Okpella, Edo state, and the restart of production at its plant at Gboko, Benue state. Sales and marketing director Rabiu Umar said that the reason behind the decision was a surge in demand leading to a ‘sold-out’ situation in the country. He added that the firm has also ceased its export programmes in order to better serve the needs of domestic consumption.

Philippines: The Philippine cement industry has met some of its investment commitments set out in the Department of Trade and Industry (DTI)’s adjustment plans for its imposition of safeguard measures against imported cement. The Manila Bulletin newspaper has reported that producers have invested around US$250m in making their product more competitive for local buyers although the industry has deferred US$1.54bn-worth of further agreed-upon spending to before 2025. The Tariff Commission (TC) said that companies’ reasons for delaying the completion of their adjustment commitments were Covid-19-led disruptions to production, transport and services. The DTI set out the commitments in the form of 20 plans, of which the industry has now fully implemented 12. The TC said that the sector is ‘determined’ to meet the remaining goals. It added that the damaging impacts of the coronavirus outbreak were lessened by the previous implementation of tariffs, which rose to US$0.20/bag in December 2020. The commission said "To date, it can be concluded that the intervention was timely and proper, as it has provided breathing space for the domestic industry and has mainly contributed to increasing the industry's market competitiveness."
