India: Nuvoco Vistas has launched Duraguard Microfibre Cement, a fibre reinforced cement. The cement’s clinker is 48-52% tricalcium silicate, with low tricalcium aluminate, and contains electrostatically precipitated dry fly ash. The producer says that it offers enhanced bonding, crack resistance, strength and durability and reduced permeability, as well as a smoother surface finish, compared with ordinary Portland cement (OPC). Nuvoco Vistas first applied for a patent for the product in mid-2018.

Managing director Jayakumar Krishnaswamy said "We prioritise innovation. Our Construction Development and Innovation Centre (CDIC) is dedicated to creating sustainable and innovative products that meet the highest global standards. The awarded patent validates our unwavering commitment to innovation and keeps us in the forefront of pioneering advances in the cement industry, delivering exceptional quality and responsible business practices."

Nigeria: Cross-industry body Manufacturers Association of Nigeria (MAN) recorded a 30% year-on-year drop in all-Nigeria cement sales during the first half of 2023. MAN attributed the decline to the government’s replacement of the naira with a new central bank digital currency. The Punch newspaper has reported that this ‘wiped out’ some cash-based businesses, including cement retailers. Point of sale charges also increased costs along the supply chain. The association said that the impacts of the policy led manufacturers in some sectors to halt their operations.

India: Adani Group subsidiary ACC has started commercial clinker production from the kiln of its new Ametha cement plant in Madhya Pradesh’s Katni District. BQ Prime News has reported that the kiln line has a clinker capacity of 3.3Mt/yr. It is capable of co-processing up to 15% alternative fuel (AF). The plant is also equipped with a 1Mt/yr grinding unit and a 16.3MW waste heat recovery (WHR) plant.

The Ametha cement plant raises ACC’s installed cement and clinker capacity by 9.8% to 37Mt/yr.

Jamaica: Caribbean Cement plans to launch an upgrade to expand its Rockfort cement plant’s capacity by 30% to 1.3Mt/yr in October 2023. The producer says that the expansion will cost US$40m and that the new capacity will come online in early 2025. The work will include enlargements of multiple kiln sections and the installation of a new coal dosing system, clinker cooler and clinker transport system.

Russia: A court has accepted a request by the Prosecutor General’s Office to drop a claim for the appropriation of Russian assets of Germany-based Heidelberg Materials by the Russian government. The assets include shares in cement producers HeidelbergCement Rus and Shale Cement Plant Cesla, as well as minerals producers Gurovo-Beton and Syryevaya Kompaniya.

A lawyer for the prosecutor’s office said “The state's interests can be protected by other lawful means.”

Heidelberg Materials suspended new investments in its Russian business on 10 March 2022. The Prosecutor General’s Office subsequently requested its expropriation, following which a court froze the assets in August 2023. Interfax News has reported that representatives of Heidelberg Materials’ Russian business then made an undertaking to the Russian government, according to which they would maintain their prices, production volumes and number of employees.

India: Dalmia Cement (Bharat) faces a potential stumbling block to its planned acquisition of Jaiprakash Associates’ cement business for US$683m due to an on-going shareholder dispute at subsidiary Jaypee Bhilai Cement. The Economic Times newspaper has reported that a court has frozen Jaiprakash Associates’ 74% shareholding in the company, and ordered it not to create new third party rights. State-owned Steel Authority of India Limited holds the remaining 26% stake in the cement producer, which operates the 2.2Mt/yr Bhilai Jaypee grinding plant in Durg, Chhattisgarh.

Dalmia Cement (Bharat) and Jaiprakash Associates concluded multiple separate agreements for the transfer of ownership of Jaiprakash Associates’ cement subsidiaries on 26 April 2023. Besides Jaypee Bhilai Cement, these include cement plant and limestone mine operator JP Super and grinding plant operator Jaiprakash Power Ventures.

South Korea: The Korean Railway Workers’ Union called a four-day strike of its 13,000 members across South Korea on 14 September 2023. Reuters has reported that the union is seeking higher pay, improved working conditions and the expansion of bullet train services into South Seoul. The Ministry of Transport predicts that total cargo haulage will drop by 53 - 79%. The Korean Cement Association (KCA) said that a protracted strike would disrupt cement production. The industry is 40% reliant on rail transport.

A representative from a KCA member said “We have secured some inventory in preparation for the strike, but it's not a lot. If the strike lengthens, we will have to convert to land transport, which will drive up costs and hit profitability."

Argentina: Holcim Argentina has awarded a contract to 360Energy to supply 30,000MWh/yr of electricity from its solar power plants. La Voz del Interior newspaper has reported that 360Energy will supply the energy from its 200MW network via the Renewable Energy Term Market (MATER). This will cover 75% of Holcim Argentina’s power consumption, corresponding to the production of 2.7Mt of cement. This will eliminate 68,600t/yr of CO₂.

Holcim Argentina chief executive officer Christian Dedeu said “I am very happy because we are taking a new step in our commitment to zero emissions in Holcim's operations, and we will continue working every day to build progress for people and the planet.”

India: Shree Cement is reportedly planning to raise US$84.4m through the sale of bonds. Reuters has reported that the bonds will mature in five years from their date of issue.

US: Terra CO₂ plans to build its first commercial-scale supplementary cementitious materials (SCM) plant in Texas. The plant will have a production capacity of 240,000t/yr. Asher Materials secured an exclusive market license to operate the plant. Terra CO₂’s SCM can replace up to 40% of cement content in concrete. Asher Materials will produce the materials from silicate rock from existing local aggregates operations.

Terra CO₂ chief science officer DJ Lake said "From start to finish, we've designed a system to create large-scale impact in the real world. Our game-changing production process converts affordable, abundant and local raw materials to cementitious material that meets rigorous performance standards.” Lake continued “True sustainability will come from deep innovations in materials and technology and not from incremental improvements to the existing cement supply chain."
