US: Argos USA has launched its new Portland Limestone Cement (PLC) brand EcoStrong.The company says the its will complete its conversion to 100% EcoStrong PLC cement production across all facilities in 2023.Its Roberta, Alabama cement plant and Atlanta, Georgia grinding plant will transition by mid-2022, while its Newberry, Florida cement plant will transition by October 2022.Argos USA plans to use EcoStrong cement at all of its Eastern US ready-mix concretesites by mid-2022.

Cement technical director Steve Wilcox said“I am excited to be part of Argos’ brand announcement for our PLC Type IL product. EcoStrong PLC encompasses everything we have worked for over the past decade, to offer a high-quality product with lower embodied carbon, which contributes to the ultimate goal of decarbonising across our operations. Our PLC product is engineered to reduce the harmful effects on the environment and perform similar to or better than our ordinaryPortland cement (OPC) Type I/II. EcoStrong PLC empowers our customers, specifiers, architects, and engineers to design and execute their projects with resilience and sustainability.”

Canada: The Government of Quebec says it will allocate up to US$36m towards a US$110m upgrade project at Ciment Québec’s integrated St Basile plant. The plant intends to build a new grinding unit including new reception, storage and raw material handling systems and two mills. The work is intended to reduce the CO₂ emissions from the plant. France-based Fives FCB previously said that it had won a contract for the project. Commissioning of the new equipment is scheduled for the beginning of 2024.

Dominican Republic: Colacem Group subsidiary Domicem has awarded the contract to upgrade the limestone reclaiming system at its integrated Sabana Grande de Palenque cement plant in San Cristóbal province to Italy-based Bedeschi. The original stacking and reclaiming equipment, installed by Bedeschi in 2004, allows clay and limestone handling at the plant. The upgraded machine will improve the limestone reclaiming system, increasing its capacity from 200t/hr to 360t/hr, the capacity needed in order to feed a new production line that is being installed at the plant.

India: Dalmia Cement (Bharat) has signed a memorandum of understanding (MOU) with Denmark-based FLSmidth to collaborate in the research and development of sustainable solutions for cement manufacturing. The agreement has been arranged under the ‘Green Strategic Partnership’ initiatives between Denmark and India that cover energy and climate change.

Under the MOU both companies will cooperate on a range of areas such as substituting conventional energy supplies with renewable sources and working towards CO₂ emissions abatement. Both companies have committed to contributing research and development towards eventually building an industrial scale production plant where the new concepts can be further tested.

Mahendra Singhi, the managing director and chief executive officer of Dalmia Cement (Bharat) said, “In alignment with the ambitious net zero vision of our Prime Minister Narendra Modiji and given the strength and stature of our respective organisations, this association will provide futuristic solutions to the cement and concrete industry to emerge clean and green.” He added that India and Dalmia Cement in particular were keen to develop a roadmap for the implementation of Industry 4.0 with totally decarbonised cement plants and a ‘lighthouse’ cement plant.

India: The Global Cement & Concrete Association (GCCA) India has released a report entitled ‘Blended Cement – Green, Durable & Sustainable’ to promote the advantages of different types of blended cement over Ordinary Portland Cement (OPC). The report was released by Anil Agrawal, Additional Secretary Department for Promotion of Industry, and Internal Trade (DPIIT), Ministry of Commerce & Industry at an online event hosted by the Indian branch of the Global Cement & Concrete Association (GCCA).

“Blended Cement is the top priority and will play a key role in decarbonising the infrastructure segment. I am happy to see that the global cement and concrete industry has taken the lead, and they have come up with a roadmap. Now the Indian cement sector is developing an India specific detailed roadmap for the cement and concrete industry to achieve the net-zero CO₂ concrete by 2050 in a time-bound manner,” said Agrawal.

The report is a collation of the information about blended cement and its advantages. It highlights the performance improvement possible through this replacement, making blended cement an attractive means to achieve sustainable infrastructure development. It also showcases the benefits of different blended types of cement over OPC based on hydration, microstructure and permeability, rheology and workability, strength development, shrinkage (chemical, autogenous, and drying) and cracks, leaching, alkali-aggregate reactivity, sulphate attack, reinforcement corrosion, long-term durability of construction and usage in preparation of high strength concrete.
