US: Amrize has launched a 'Made in America' label for its cement to offer builders ‘the guarantee of American manufacturing and quality, while supporting American jobs and local communities.’ The label signifies that all aspects of the cement are made in the US, including all of its raw materials.

Roll-out of the label will begin at Amrize's flagship cement plants at Ste. Genevieve, (Missouri), Midlothian (Texas), Devil's Slide (Utah), Holly Hill (South Carolina) and Portland (Colorado). The company, already the largest in the US by installed capacity, is investing US$700m in its cement plants during 2025.

“Our new 'Made in America' label offers our customers the confidence that their product complies with US standards for quality, performance and reliability, with local-to-local service,” said Jaime Hill, President of Amrize Building Materials. “We are proud of the role our solutions play in building America and are committed to advancing the US building industry, supporting American jobs and serving as the partner of choice for the professional builders of America.”

Asia: Three national sustainability certification providers have signed a tripartite mutual recognition agreement for harmonised green label criteria for cement products. Ecolabel Sri Lanka, the Singapore Green Labelling Scheme and Thai Green Label agreed to the mutual recognition of each other’s certification of cement. Through the collaboration, the bodies aim to enhance market access to environmentally preferable products across South and South East Asia, Daily FT News has reported.

Philippines: The Department of Trade and Industry (DTI) is updating its regulatory framework for cement to ensure safer and more durable materials for infrastructure.

Trade Secretary Cristina Roque said “Given our country’s vulnerability to natural disasters, we must ensure that all construction materials, including cement, meet the highest quality and safety standards. This ensures the safety of Filipinos, starting from the foundational materials of our homes and buildings.”

The DTI is revising Department Administrative Order 17-06:2017, with proposed rules calling for post-shipment inspection and full product testing of cement. Public and stakeholder comments on the draft circular will be accepted until 4 November 2025. As of September 2025, the DTI reported 179 active cement manufacturer licensees, comprising 95 for Portland cement, 81 for blended hydraulic cement and three for masonry cement. All are compliant with Philippine National Standards.

Bahrain: New rules have placed strict demands on local producers and importers. A regulation signed by Industry and Commerce Minister Abdulla bin Adel Fakhro requires all cement sold in Bahrain to meet BS EN 197-1 and GSO ASTM C150 standards and be circulated with a conformity certificate from the Bahrain Standards and Metrology Directorate. News of Bahrain has reported that there will be regular laboratory testing, specific storage and transport conditions, and penalties for non-compliance. The move reportedly marks a push to raise the standard of construction materials.

Vietnam: The general director of Vietnam Cement Industry Corporation (VICEM), Nguyen Thanh Tung, says that Vietnam will suffer continued cement overcapacity amid high production costs in 2025. Full-year production is forecast at 125Mt, 96% greater than an expected domestic demand of 63.5Mt. Việt Nam News has reported that Vietnam’s cement exports face an on-going investigation in Taiwan, and are already subject to anti-dumping duties in the Philippines.

VICEM aims to raise its domestic clinker sales volumes by 8% year-on-year to 18Mt, in order to generate sales of US$1.16bn. To this end, Tung urged the government to adopt cement reinforcement in roadbuilding, as well as lifting the export tax on cement.

Taiwan: Taiwan Cement Corporation (TCC) and 100 construction firms have together launched the Low Carbon Construction Pioneer Alliance. CNA News has reported that the founding members eliminated 146,000t of CO₂ emissions altogether through their use of reduced-CO₂ building materials since November 2024. This includes despatches of 800,000m³ of Portland limestone cement (PLC) concrete by TCC, with 2.5Mm³ in cumulative orders to date. TCC first launched its PLC in October 2023, touting an emissions reduction of 15% compared to ordinary Portland cement (OPC). It since enlarged the net reduction to 24% through production modifications.

Taiwan Cement chair Zhang Anping said "TCC took the initiative to align with the Global Cement and Concrete Association and released the lowest-carbon PLC concrete in Taiwan. The CO₂ reduction is far greater than the 53% as defined by the government.”

India: Shree Cement's Ras quality control laboratory in Rajasthan has been recognised by the National Accreditation Board for Testing and Calibration Laboratories (NABL), affirming its compliance with the ISO/IEC 17025:2017 standards. Managing Director Neeraj Akhoury said that the accreditation acknowledges the company's commitment to providing premium, sustainable building materials. The laboratory's role in ensuring standardisation across all product testing is important for maintaining production quality at the plant.

One unusual thing about coverage of cement in the media is the way that discussions often centre precisely on its absence – that is, on alternatives to cement. These alternatives boast unique chemistries and performance characteristics, but are all produced without Portland cement clinker. They are generally called ‘alternative cements,’ perhaps because ‘cement-free cement’ does not have such a commercially viable ring to it. This contradictory tendency reached a new high in the past week, with developments in alternative cement across Asia, Europe, the Middle East and North America. Together, they hint at a more diverse future for the ‘cement’ industry than the one we know today.

Asia

In Indonesia, Suvo Strategic Minerals has concluded tests with Makassar State University of a novel nickel-slag-based cement. Huadi Nickel-Alloy Indonesia supplied raw materials, and tests showed a seven-day compressive strength of 37.5MPa. Suvo Strategic Minerals says that a partnership with Huadi Nickel-Alloy Indonesia for commercial production is a likely next step.

Europe

Cement producer Mannok and minerals company Boliden partnered with the South Eastern Applied Materials (SEAM) research centre in Ireland to launch a project to develop supplementary cementitious materials (SCMs) from shale on 7 October 2024. The project will additionally investigate CO₂-curing of cement paste backfill for use in mines. Irish state-owned global commerce agency Enterprise Ireland has contributed €700,000 in funding.

UK-based SCM developer Karbonite expects to launch trial production of its olivine-based SCM with a concrete company in 2025. The start-up launched Karbonite Group Holding BV, with offices in the Netherlands, to facilitate this new phase. Karbonite’s SCM is activated at 750 – 850°C and sequesters CO₂ in the activation process, resulting in over 56% lower CO₂ emissions than ordinary Portland cement (OPC). Managing director Rajeev Sood told Global Cement that talks are already underway for subsequent expansions into the UAE and India.

Back in the UK, contractor John Sisk & Son has received €597,000 from national innovation agency Innovate UK. John Sisk & Son is testing fellow Ireland-based company Ecocem’s <25% clinker cement technology in concrete for use in its on-going construction of the Wembley Park mixed development in London.

At the same time, Innovate UK granted a further €3.23m to other companies for concrete decarbonisation. Recipients included a calcined clay being developed by Cemcor, an SCM being developed from electric arc furnace byproducts by Cocoon, a geopolymer cement technology being developed by EFC Green Concrete Technology UK and an initiative to develop alternative cement from recycled concrete fines at the Materials Processing Institute in Middlesbrough. Also included was the Skanska Costain Strabag joint venture, which is working on the London stretch of the upcoming HS2 railway. The joint venture, along with partners including cement producer Tarmac and construction chemicals company Sika UK, will test low-kaolinite London clay as a raw material with which to produce calcined clay as a cement substitute in concrete structures in HS2’s rail tunnels.

Middle East

Talks are underway between UK-based calcined clay producer Next Generation SCM and City Cement subsidiary Nizak Mining Company over the possible launch of a joint venture in Riyadh, Saudi Arabia. The joint venture would build a 350,000t/yr reduced-CO₂ concrete plant, which would use alternative cement based on Next Generation SCM’s calcined clay.

North America

Texas-based SCM developer Solidia Technologies recently patented its carbonatable calcium silicate-based alternative cement, which sequesters CO₂ as it cures.

Meanwhile, C-Crete Technologies made its first commercial pour of its granite-based cement-free concrete in New York, US. C-Crete Technologies says that the product offers cost and performance parity with conventional cement, with net zero CO₂ emissions. Its raw material is globally more abundant than the limestone used as a raw material for clinker. Other abundantly available feedstocks successfully deployed within C-Crete Technologies’ repertoire include basalt and zeolite.

Across New York State, in Binghamton, KLAW Industries has succeeded in replacing 20% of concrete’s cement content with its powdered glass-based SCM, Pantheon. KLAW Industries has delivered samples to local municipalities and the New York State Department of Transportation. Its success expands the discussion of possible circular cement ingredients from the industrial sphere into post-consumer resources.

In Calgary, Canada, a novel SCM has drawn attention from one of the major cement incumbents: Germany-based Heidelberg Materials. It invested in local construction and demolition materials (CDM)-based SCM developer EnviCore on 9 October 2024. The companies plan to build a pilot plant at an existing Heidelberg Materials CDM recycling centre.

Conclusion

Alternative cement developers are still finding the words to talk about their products. They may be more than ‘supplementary’ up to the point of entirely supplanting 100% of clinker. Product webpages offer ‘hydraulic binder,’ ‘pozzolan’ and even ‘cement.’ As alternative ‘cements’ are developed, they build on the work of pioneers like Joseph Aspdin and Louis Vicat. Start-ups and their backers are now reaching commercial offerings, on a similar-but-different footing to cement itself. None of these novel materials positions itself as the sole, last-minute ‘super sub’ in the construction sector’s confrontation with climate change. Rather, they are a package of solutions which can combine into a net zero-emissions heavy building materials offering, hopefully before 2050.

Related to this is the need for ‘technology neutral’ standards, as championed this week by the Alliance for Low-Carbon Cement and Concrete (ALCCC), along with 23 other European industry associations, civil society organisations and think tanks. The term may sound new, but the concept is critical to the eventual uptake of alternative cements: standards, the ALCCC says, should be purely performance-based. They ought not attempt to define what technology, for example cement clinker, makes a suitable building material. According to the ALCCC, Europe’s building materials standards are not technology neutral, but instead ‘gatekeep’ market access, to the benefit of conventional cement and the exclusion of ‘proven and scalable low-carbon products.’

At the same time, cement itself is changing. Market research from USD Analytics showed an anticipated 5% composite annual growth rate in blended cement sales between 2024 and 2032, more than doubling throughout the period from US$253bn to US$369bn. If you can’t beat it, blend with it!

For a further discussion of alternative cement and binders in Europe, see Global Cement’s interview with ALCCC co-ordinator Joren Verschaeve in the forthcoming November issue of Global Cement Magazine on 17 October 2024.

Pakistan: The Senate Standing Committee on Science and Technology heard on 10 October 2024 that some cement producers have obtained stay orders from courts against the Pakistan Standards and Quality Control Authority over unpaid marking fees. The marking fees equate to 0.1% of cement’s ex-factory price, and go towards ensuring that cement conforms to standards. Pakistan Today News has reported that only two producers have regularly paid the fee, with combined defaults valued at US$18m across the entire industry. A delegation from Saudi Arabia reportedly queried authorities about the lack of clear labelling.

Science and Technology Committee chair Kamil Ali Agha reportedly said "No one knows what quality of cement is being produced by local manufacturers.”

Tanzania: The Tanzania Revenue Authority (TRA) has introduced a new digital verification application named Hakiki Stempu, aimed at helping consumers verify the quality of cement products and combat the sale of counterfeit and substandard cement.

Ndositwe Haonga, TRA Director for Internal Affairs, explained that Hakiki Stempu allows the public to check whether the product they are about to purchase is genuine or not by scanning the product to check if it has the right tax stamp. The app also serves as a tool for ensuring that products meet necessary standards and offer value for money.
