India: Wonder Cement’s managing director Kiran Patil led the inauguration of Line 5 at the Nimbahera plant in Rajasthan on 7 May 2025, according to a social media post by the producer. The project increased the producer’s clinker capacity by 2.8Mt/yr to 13.35Mt/yr and cement capacity by 2.5Mt/yr to 21.5Mt/yr. The company partnered with APBCO on the expansion, which also includes a 12MW waste heat recovery system to increase energy efficiency.

Kenya: Kenya’s cement clinker imports have dropped by 93% year-on-year to 10,340t in 2024 from 148,000t in 2023, according to the government’s 2025 Economic Survey. The value of imported clinker fell to US$27,500 from US$409,000 in 2023 and US$3.2bn in 2020. Import volumes had already fallen by 77% in 2023, from 656Mt in 2022.

Cement production declined by 7% from 9.6Mt to 8.9Mt in 2024, while consumption also fell by 7% to 8.5Mt. Construction sector growth contracted by 0.7% in 2024, down from 3% in 2023.

Spain: Cement consumption in Andalusia rose by 13% year-on-year in the first quarter of 2025 to 763,000t, according to the Andalusian Cement Manufacturers Association (AFCA).

In March 2025, consumption reached 254,000t, up by 12% year-on-year. However, clinker and cement exports fell by 9% to 97,600t during the same period.

AFCA president Ricardo de Pablos said “The first quarter of the year reflects a positive trend in cement consumption and, therefore, in construction sector activity.”

De Pablos added that building permits for new homes grew by 31% in 2024, with 31,296 homes authorised for construction throughout 2025, but warned that no investment growth is expected in 2025.

Uganda: Lands, Housing and Urban Development minister Judith Nabakooba said that the government and the Naita-A-Tepeth Communal Land Association have finalised a lease agreement to enable Tororo Cement to build Uganda’s first clinker plant in Katikekile, Moroto District. Nabakooba said that the project began in 2023, and will reduce clinker imports and conserve foreign exchange.

According to a social media post by the ministry, the agreement includes the sale of 202 hectares to Tororo Cement for the plant site, the lease of 3824 acres to the Uganda Investment Authority and the titling of institutional land for local public use.

US: France-based Fives Group has launched new subsidiary Fives FCB USA in Alabama to supply the North American market with low clinker blended cement and supplementary cementitious material production equipment and services. Products being promoted include the FCB Horomill, the FCB TSV Classifier and the FCB Rhodax. The unit will share premises with Fives’ North American Construction Services company.

Deputy general manager Alain Cordonnier said “The opening of our subsidiary in the US marks a significant milestone for Fives FCB. We are excited to bring our innovative technologies and expertise to the US market, and we look forward to building strong partnerships with local industry leaders.”

Anhui Conch Cement held an event in Wuhu, China, this week showcasing its new artificial intelligence (AI) model for the cement sector. The cement company and Huawei started the project in April 2024 with the support of the China Building Materials Federation. The companies say they have now identified over 200 “promising AI application scenarios across 15 categories” across the entire production process from quarrying to packaging and logistics. Conch has set up an AI training centre using the Huawei Cloud Stack product. It is using Huawei’s Pangu prediction, computer vision (CV) and natural language processing (NLP) models to create an AI operating system that integrates central training, edge inference, cloud-edge synergy, continuous learning and ongoing optimisation.

Thankfully Huawei gave some examples of what this actually meant for operators in the real world. The model is able to give real-time recommendations of key quality features enabling the prediction of three-day and 28-day clinker strength. The predicted strength values closely match test results, with deviations within 1MPa and an accuracy rate exceeding 85%. Other benefits include reducing kiln fuel consumption by 1%, monitoring and managing various components and machines along the production line, staff safety gains and creating a ‘smart digital assistant’ that can answer technical questions from employees.

Little of this seems particularly novel, so far, compared to what other companies are already doing in this field. For example, ABB said in early 2022 that it was using machine learning to predict 28-day strength on the day of sampling and in 2023 that it was doing it using production data provided every two - three hours. Another example is the work that Inform does using AI-based software to support logistics for heavy building materials. Plenty of other western-based companies also offer production optimisation and/or predictive maintenance products.

Conch’s use of an NLP model to create a knowledge base assistant does seem new for the cement sector. Although how specific the software running it might be to one business or industrial area remains to be seen. One could easily imagine this kind of product being sold to lots of different kinds of industries in the manner of current enterprise style software. Along these lines though, Juan Beltrán, digital manager of global sales excellence at Holcim, told McKinsey in an interview about Holcim’s pilot project in Spain testing an AI-enabled copilot customer-ordering assistant via WhatsApp.

Recent events in AI for the cement sector include ABB’s agreement to work with UK-based Carbon Re in late 2024. This collaboration was intended to combine ABB's expertise in automation and process control with Carbon Re's AI and machine learning technologies. It followed a pilot at a cement plant in the Czech Republic. On the producer side, Holcim said in mid-2024 that it was preparing to expand the use of AI-based software to 100 production plants by 2028. It noted that it had installed the system at 45 plants so far at the time of this announcement and that it was using a predictive maintenance solution from software supplier C3 AI. Titan Cement said that it had invested in Spain-based AI software supplier Optimitive in February 2025. Then, Cemex announced this week that it too had invested in Optimitive, via its corporate venture capital arm Cemex Ventures. Molins has also worked with Optimitive.

What isn't being disclosed much are the examples of the mistakes of introducing AI into cement production. These are valuable learning opportunities for any company implementing this kind of software. However, the developers and cement producers are extremely unlikely to admit anything publicly. Global Cement Weekly has heard off-the-record information previously about AI projects at cement plants that have gone wrong but we can’t reveal it either. To his credit though Beltrán mentions an incident, in his interview with McKinsey, where the WhatsApp ordering assistant was tricked during testing into almost placing an order for a truck of gazpacho soup!

We’re still watching how AI is being deployed in heavy industries such as cement. The announcement by Conch is exactly the kind of thing its peers are doing around the world. So far what they’ve done is impressive but not unique. Yet, China’s large but shrinking cement sector and its determination to develop its own AI-based software sector may start to deliver more cutting-edge advances in the future. Companies elsewhere are also pressing ahead to find out how AI products will deliver efficiency gains.

China: According to China Cement Net, Chongqing Tongliang Southwest Cement has inaugurated a 7300t/day (2.25Mt/yr) clinker production line. The company previously operated a 2500t/day (0.75Mt/yr) and a 4800t/day (1.55Mt/yr) clinker line, which will be relocated.

Nepal: Udayapur Cement Industry resumed operations on 24 April 2025, despite ongoing legal disputes and internal administrative obstructions, according to acting general manager Mahesh Sah. The plant ceased all activities in late November 2024. It began kiln firing at 10:40am local time and expected clinker production to begin after eight hours of machine operation.

The plant aims to produce approximately 400t/day of clinker. Coal and dinepalesel stocks are expected to last 12 days. Sah noted that coordination has been made with the Nepal Electricity Authority, which has assured uninterrupted power supply despite outstanding dues. Udayapur Cement, a fully state-owned enterprise, has a daily production capacity of 800t/day.

Ghana: CBI Ghana has invested US$100m in a new plant in Tema to produce limestone calcined clay cement (LC3) using local raw materials, to reduce reliance on imported clinker.

Commercial director of Supacem Kobby Adams said that the Ghana Standards Authority’s adoption of the GS PAS 5:2024 LC3 standard enabled the launch, following collaboration with local universities and international partners. According to Graphic Business news, the current clinker scarcity and its escalating prices stemmed from a 6% currency depreciation between December 2024 and February 2025 and the evolving global market uncertainties, including an increase in clinker export prices from the Mediterranean.

The project reportedly created over 160 direct jobs through local sourcing and infrastructure development in Tema and Torgome.

Malaysia: Cahya Mata Sarawak (CMS) subsidiary Cahya Mata Cement is seeking approval from the Sarawak government to begin construction of a second clinker production line in Mambong. The line was first announced in January 2025. According to Bernama news, the new line will more than double the producer’s clinker capacity to 1.92Mt/yr from 900,000t/yr and is scheduled for completion in March 2027. Once operational, it will enable the group to manufacture up to 2.4Mt/yr of cement.

The project will be developed with China-based Sinoma Industry Engineering under a consulting agreement signed in 2023. The agreement covers the design and subsequent construction of the clinker line, as well as optimisation of the existing production line. The line will include a 6MW waste heat recovery system and a dust filtration system to cut emissions by 50%.

CMS group general counsel Izzam Ibrahim said “We are going through the regulatory approvals, and we are working very closely with the state government to obtain approval to start construction. In fact, we have lined up all the necessary manpower and procurement processes to kickstart the project. Once the project is off the ground, the target for completion will remain on track.”
