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.

Rivas holds an undergraduate degree in mechanical engineering from the Universidad Simón Bolívar.

Dominican Republic: Sinoma CBMI Latin America has celebrated the completion of the PANAM cement project in the Dominican Republic. The project involved construction of a ‘modern’ cement grinding plant for Cemento PANAM, part of Grupo Estrella. According to a post on social media by Sinoma, the plant has a production capacity of 1.23Mt/yr, and integrates ‘advanced, carbon-neutral technologies’ to reduce environmental impact. The plant features a Gebr. Pfeiffer vertical roller mill with a capacity of 155t/hr of cement.

US: Eco Material Technologies has announced the opening of the Blissville Rail Terminal in Queens, New York. The new terminal will enable Eco Material to distribute approximately 50,000t/yr of fly ash from its national network to support local infrastructure projects in the New York metro area. The terminal will utilise rail transportation to deliver fly ash and cementitious materials, which the company says can replace up to 25% of carbon-intensive Portland cement in standard concrete mixes, with Eco Material's technologies reportedly allowing for up to 100% replacement in select applications.

"The opening of the Blissville Terminal is a major step in our efforts to expand access to low-carbon cement alternatives in all major metro areas, " said Grant Quasha, CEO of Eco Material Technologies. "By strengthening our presence in New York, we can better serve future infrastructure projects with innovative materials that reduce reliance on traditional Portland cement and imported steel slag.”

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.

Myanmar: Authorities are working to expedite the reopening of cement plants in Kyaukse, Mandalay Region, following the earthquake in late March 2025, according to the Global New Light of Myanmar newspaper. Kyaukse District administrator U Kaung Myat Naing said that one plant expects to resume supplying 100,000 bags of cement per day by mid-May 2025. The reopening of cement plants will help to meet the growing demand in the country.

Puerto Rico/Turks & Caicos: Cementos Argos has successfully shipped 1335 bags of cement to Turks & Caicos from Puerto Rico, according to a social media post by the producer. The company said that the milestone demonstrates its ability to bring reliable and sustainable solutions to where they are needed.

India: UltraTech Cement reported consolidated net sales of US$2.67bn in the fourth quarter of the 2025 financial year, up from US$2.35bn year-on-year. Profit before interest, depreciation and tax rose to US$554m from US$498m, while profit after tax grew to US$291m from US$265m.

UltraTech commissioned 17.4Mt/yr of capacity during the period, raising its domestic grey cement capacity to 183Mt/yr and its global capacity to 188.76Mt/yr.

The company achieved 1GW of renewable power installations, which it says makes it the first industrial company in India to commission 1GW of renewable capacity for captive use. It added 269MW of renewable power during the quarter, bringing its total renewable energy capacity to 1.363GW, including waste heat recovery systems. This covers 46% of Ultratech’s current power needs.

Nigeria: Dangote Cement recorded a profit after tax of US$131m for the quarter ending 31 March 2025, up by 86% from US$70.5m in the same period of 2024. Revenue rose by 22% year-on-year to US$623m, driven largely by strategic pricing initiatives in Nigeria, where revenue grew by 54%. Gross profit rose to US$368m from US$262m, while profit before tax increased by 87% to US$195m from US$104m. Group earnings by interest, taxation, depreciation and amortisation (EBITDA) surged by 49% to US$289m.

The group’s cement volumes declined by 7% to 6.6Mt during the quarter, reflecting reduced demand and heightened inflationary pressures across key markets. However, export volumes grew by 21%, supported by eight clinker shipments to Ghana and Cameroon.

Malaysia: The state government of Sabah has dismissed concerns over illegal logging, investor withdrawal and environmental risks related to the US$277m Tongod cement plant project.

Masiung Banah of the Sabah State Legislative Assembly said "There is no logging taking place. The quarry spans 200 acres [80.9 hectares], not thousands as claimed. The project has undergone thorough environmental assessments, including an Environmental Impact Assessment (EIA), to ensure compliance with regulations."

Masiung, also chair of Borneo Cement, said that the project is proceeding as planned and that site clearing had already begun, following the approval of the EIA, according to the Daily Express newspaper. He added that the 5000t/day plant in Kampung Kayawoi will address Sabah’s cement shortage, reduce prices through local sourcing and create up to 1000 jobs for local people, as well as improving roads, electricity and water supply in the region. The Sabah Energy Commission has reportedly agreed to supply 40% of the plant’s required electricity and a 26km access road will be built to transport materials.
