Alliance for Low-Carbon Cement & Concrete counts nine new members
01 September 2023World: Nine new members have joined the Alliance for Low-Carbon Cement & Concrete (ALCCC), a global association of low-CO2 cement and concrete developers, producers and users, since its launch in May 2023. The alliance has welcomed alternative cement and concrete companies Betolar, 3Béton, CarbonRE, Cemvision, the European Environmental Bureau, Greenmade, Materrup, Nomad and Sublime Systems.
Joren Verschaeve, Programme Manager at ALCCC founder Environmental Coalition on Standards, said “It is great to see that so many actors - particularly innovators from within the industry - are committed to speeding up the decarbonisation of cement and concrete through better standards and policies. We are eager to work with our members and other stakeholders to (finally) help put the right incentives in place for low-carbon cement and concrete solutions.”
Update on cement and concrete standards
03 May 2023Betolar has called today for a global performance-based standard to replace existing prescriptive standards. Riku Kytömäki, the head of Betolar, argued at the London-based Concrete Expo that the lack of a performance-based standard is holding back the use of low-carbon materials from replacing cement in concrete production. He said “the current regulations across the markets are restricting the use of circular materials allowed in concrete buildings.” Betolar produces Geoprime, an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). This gives the company a financial reason to want standards to change, as it will potentially allow it to sell more of its product. However, as the company points out, “there is a huge need for new alternatives.” The world needs around 4Bnt/yr of cement but there is only 300Mt/yr of slag available.
Building materials producers and related companies wanting to change rules and standards in response to new trends is a common refrain. For instance, the increased use of alternative fuels by the cement sector has prompted all sorts of regulatory changes. However, rather than simply asking for amendments to the existing ways of doing things, Betolar is advocating for more wholesale change. It isn’t alone. Also this week the ASTM in the US announced that it is writing a specification to include a wider range of secondary cementitious materials (SCM). In addition, many of the interviews Global Cement Magazine has conducted with companies developing and marketing new types of cement and concrete in recent years have said similar things. Examples include the use of graphene, carbon nanotubes or sequestering CO2 into industrial by-products to create novel secondary cementitious materials (SCM).
Prescriptive versus performance-based approaches to buildings and building materials tie into wider design philosophies about construction. The prescriptive approach provides detailed descriptions of regulations, methods and components, such as cement and concrete standards. With respect to concrete standards, this might mean setting mandatory SCM and cement proportions, determining allowable water content, certain types of aggregate to be used and so on. The performance approach focuses on the end results, although it can be just as codified and standardised as the prescriptive route. For concrete, for example, this means that performance is measured by standard test methods with defined acceptance criteria stated in the contract documents with no restrictions on the parameters of concrete mixture proportions.
For cement and concrete standards the prescriptive approach dominated in Europe and North America in the 20th century. However, this began to change in the US in 2002 when the National Ready Mixed Concrete Association (NRMCA) started working on its roadmap towards its Prescription to Performance (P2P) initiative. The key aim of the scheme was to shift the emphasis from prescribing (or indeed proscribing) the ingredients and their proportions in a concrete mixture to an emphasis on the performance properties of the combined materials. A decade later in the mid-2010s it found during a progress review that about half of the sample of project specifications studied were classified as ‘prescriptive.’ The biggest prescriptive restriction was on the quantity of SCMs set by specification writers. These were often percentages required in certain circumstances, such as freezing and thawing cycles, but imposed on all usage.
The current bout of interest in performance-based standards appears to be driven by the growing demand for cement and concrete products to lower their clinker factor by using higher amounts of SCMs. A far wider range of SCM-based products are being developed and coming to market and then encountering regulatory burden. These new material manufacturers are meeting up with the sustainability lobby, which also has an interest in decarbonising building materials. In 2022, for example, the Belgium-based Environmental Coalition on Standards (ECOS) started pushing for performance-based standards for cement. In a statement it said that, “it is commonly accepted that prescriptive specifications are convenient, but that this convenience is obtained at the expense of (eco-) innovation and decarbonisation.” It added that the switch to performance-based standards would also strengthen the European internal market for construction products as part of the Construction Products Regulation (CPR). It noted the ASTM standards for hydraulic cements (ASTM C-1157), that were developed in the 1990s in the US, and more recent developments in the field in Latin America.
It is worth pointing out that the prescriptive route does have its advantages. Using a prescriptive system is easier for less-experienced practitioners or generalists as it sets a minimum standard, even if it is over-engineered. Responsibility is shared out among the supply chain under a performance-based system for the quality of concrete. Under a prescriptive system, the supplier or contractor can be held responsible for quality control issues. For the performance approach this has to be specifically defined, although systems are in place to help. Making it harder via ‘red tape’ for new products to enter a market may stifle innovation but it also gives these new products far more time to be tested rigorously.
The whole prescriptive-performance standards issue opens up the wider implications of decarbonising construction materials. Where once there was a relatively small number of different types of cement and concrete now there are potentially hundreds, each looking for market share. Whether this situation will be the same in a decade’s time remains to be seen. A few common SCM-based cement and concrete products and formulations may predominate. For now, the future seems wide open and bigger changes, such as the global performance-based standards Betolar is advocating, may be required to support this. Considering the massive variation between countries and states, even within the US and the European Union, let alone the rest of the world, this seems ambitious. But it is not impossible!
Betolar calls for a global performance-based standard to support low-carbon building materials
03 May 2023UK: Riku Kytömäki, the chief executive officer of Betolar, has called for a global performance-based standard to replace the current building requirements that restrict the use of new low-carbon materials to replace cement in concrete production. He made the comments at the London Concrete Expo. Kytömäki argued that current standards state that concrete manufacturers must use a certain percentage of cement to strengthen the finished product. Betolar’s product Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). However, “ageing” standards rule out the use of these kinds of products such as this despite their sustainability advantages.
Kytömäki said “It is time for global concrete industry to step up their sustainability efforts. New material innovation is available. It is cost-effective and helps to meet stricter durability requirements. However, the current regulations across the markets are restricting the use of circular materials allowed in concrete buildings.” He added that his company’s product Geoprime, “does not require large investments, but there is regulation to be developed quickly so that new solutions and materials can be used."
Betolar says it has analysed over 200 side-streams other than slag and fly ash, providing flexibility to process locally available side-streams. It added that there are also significant CO2 savings to be found in logistics when manufacturing processes take place near the source of the industrial side-streams.
Betolar appoints Riku Kytömäki as president and CEO
02 November 2022Finland: Geoprime producer Betolar has named Riku Kytömäki as its new president and CEO. Riku's professional background is in materials technology, having served as president and CEO of Exel Composites and held senior positions in Switzerland-based ABB. Kytömäki holds board positions in several international companies and organisations, including polymers producer Teknikum Group. He has management experience in Asian markets where Betolar has expanded during the past few years.
Betolar said "Riku will lead Betolar through its next growth phase as its Geoprime solution is entering active production. Geoprime is a next-generation, low-carbon solution and sustainable alternative to cement: it delivers 80% fewer emissions and 100% cement-free building materials with the same performance as traditional concrete."
India: Three new Indian concrete companies have separately secured agreements for the use of Finland-based Betolar’s Geoprime alkali-activated slag and fly ash additive. Reuters News has reported that the companies are Balaiji Cement Products, Shiv Tiles and SNEH Precast. Engineering company Godrej & Boyce has also signed a letter of intent with the supplier for pilot production of concrete blocks, paving slabs and other elements.
Betolar expects producers to achieve global concrete production volumes of 250,000t/yr of concrete containing Geoprime by 2023.
Finland: Betolar has signed a letter of intent with Australia-based RISAB and the Vanadium Recovery Project to research the use of steel slag from which vanadium has been extracted in concrete production. Dow Jones Institutional News has reported that the company says that, through it Geoprime alkali-activated additive technology, the new slag source could replace 10% of the cement used in concrete production in Finland.
CEO Matti Löppönen said "We see a huge opportunity for Betolar here. If successful, we would be able to offer our customers a specific, currently unused slag of the steel industry to replace cement in concrete. Our customers already have experience in utilising other types of slag in the production of concrete using Geoprime. Utilising new side streams will expand the reach of our solution as planned.”
Betolar launched Geoprime in September 2021. It is currently developing a recipe-optimising artificial intelligence (AI) and data platform to bring together concrete producers and suppliers of slag, ash and other materials.
