Ireland: Ecocem has launched Superfine, a ground granulated blast furnace slag (GGBS) for use in specialist applications in the European market. The product is a GGBS that has been ground to a very fine particle size. It is intended to be added to other products to improve their strengths in applications such as high performance and ultra-high-performance concrete (UHPC). It can also be used to improve the finish of concrete and reduce the amount of pigment required.

Superfine will be launched across Europe, with the product already being trialled in Abu Dhabi and specified in projects across Ireland. It is designed to be used as a specialist additive in binders, industrial mortars, ultra-high performance concrete (UHPC) and precast concrete.

Susan McGarry, the managing director of Ecocem Ireland, said “After extensive time in research and development, launching Superfine onto the Irish market is testament to our global range of innovative and sustainable concrete solutions.”

Sri Lanka: Insee Cement has broken ground on its construction of a 45,000m3-capacity storage facility at Hambantota International Port. When commissioned in early 2023, the facility will store ground granulated blast furnace slag (GGBFS) for use in Insee Cement's cement production. Daily News has reported the cost of the facility's construction as US$3m. At 17,300m2, the Hambantota storage facility will be the largest warehouse at any port in Sri Lanka.

Insee Cement chair and CEO Nandana Ekanayake said "Hambantota Port is a vital link in our raw materials supply chain. Insee Cement has been using this port since 2018 and so far we have cleared around 1.7Mt of bulk cargo through the port, of which we did a little over 1Mt in 2021. Today, we laid this foundation as another step to strengthen our partnership with Hambantota International Port Group." Ekanayake concluded "We see great potential in developing channels through Hambantota International Port and we will double our investment in the future."

US: The Slag Cement Association (SCA) has released the curriculum for its Slag Cement University. The initiative is intended to be an educational resource on slag cement use in concrete construction for university professors and students. Teachers are encouraged to incorporate the content into existing construction management course material. The educational material was curated and developed by SCA members and staff to provide an overview of the applications, uses, and benefits of slag cement use. Content includes syllabus, exam questions, slide decks, and pre-recorded presentations on various topics.

Sri Lanka: Insee Cement's Ruhunu cement plant in Galle has begun producing Portland composite cement (PCC) using slag and fly ash. Insee Cement first produced PPC at its Puttalam cement plant.

Insee Cement's head of products and solutions Moussa Baalbaki said "Insee Cement introduced PCC for the first time to the local market in 2021 as part of a two-pronged approach: to create value for our customers by augmenting the sustainability performance in their constructions, and also to steer Sri Lanka's construction industry towards ambitious, globally benchmarked sustainable goals." Baalbaki continued "We are truly encouraged by the growing demand across the local market for PCC, and trust our production expansion to Galle is testimony to our commitment towards sustainable production practices."

Australia: Hallett Group plans to establish a slag cement grinding plant in Port Augusta, South Australia. Magnet News has reported the cost of the project as US$83.9m, towards which the producer has received US$13.4m in government funding. The plant will produce cement using South Australian ground granulated blast furnace slag (GGBFS) from Nyrstar’s Port Pirie and Liberty Primary Steel’s Whyalla steel refineries and fly ash from the site of the former Port Augusta power plant. Its operations will be 100% renewably powered. An accompanying new distribution facility at Port Adelaide will ship the cement to markets. The project will create 50 new jobs.

When the Port Augusta grinding plant becomes operational in 2023, its products will reduce regional CO₂ emissions by 300,000t/yr, subsequently rising to 1Mt/yr, according to the company’s expansion plans.

Hallett Group chief executive officer Kane Salisbury said "We're talking about 1% of the entire country's 2030 [CO₂ reduction] commitment, delivered through this project." Salisbury added "We're looking at turning South Australia into a global leader in manufacturing green cement."
