The Portland Cement Association (PCA) is currently considering changing its name as part of a wider rebranding exercise. As the PCA’s president and CEO Mike Ireland puts it, “Portland cement no longer adequately represents the products PCA member companies manufacture, as they increasingly produce blended cements in today's environmentally conscious marketplace.” The exercise opens up a host of issues about the promotion of cement and concrete and the role of a trade association in the 21st century.

The reason the PCA holds its name is because ordinary Portland cement (OPC) became the most popular type of cement used to make concrete (and other building materials) in the second half of the 19th century. This continued in the 20th century without any issues. So naming a national cement association after the sector’s key product made sense at the time. The parent organisation that became the PCA was formed in 1902 and the PCA proper officially started in 1916 when cement producers met in Chicago and agreed to set up an expanded organisation.

One topic that was less of an issue in 1916, was considering a national cement association in an international context. Or in other words, should a national or regional cement association say where it is from in its name? Many associations do so elsewhere in the world but not all. Cembureau in Europe, the Cement Manufacturers’ Association in India and the Mineral Products Association in the UK for instance are three examples that do not. The PCA’s current name does not indicate where it is based and it has appeared to have coped for over 100 years. Curiously though, most of the suggestions that the PCA has put forward for its potential new name do include ‘America’ in some shape or form. Another connected problem is whether the general public in the US make the assumption that the PCA is a smaller group based in Portland, Oregon!

Mike Ireland points out another dilemma facing the PCA today with the rise in popularity of blended cements. The PCA, for example, worked on supporting the use of Portland Limestone Cement in the 2010s before lots of US producers started making it in the 2020s. To illustrate the scale of the change that this and other initiatives have created, United States Geological Survey (USGS) data shows that shipments of blended cements doubled from 26Mt in 2022 to just under 55Mt 2023. At the same time, shipments of Portland Cement fell by 37% year-on-year to around 52Mt from 83Mt. More blended cements were shipped in the US than OPC in 2023. So the PCA finds itself named after a minority cement product.

The other issue that Ireland touches upon is the environmental perception of cement by the general public and the problems for marketing, branding and advocacy this presents to a trade association. Simply put, it is far easier for the environmental lobby in developed economies to portray cement as ‘bad’ than it is for the cement sector to publicise the many small but incremental changes it has made or the monumental effect that cement and concrete have made upon human society over the last 150 years. Although it may not mean much to the wider public, to whom ‘cement is cement,’ the rise of blended cements in the US has handed the PCA the opportunity to differentiate cement into ‘good’ and ‘bad’ offerings. In this case high CO₂ emitting OPC becomes the old dirty product of the past and blended cements become clean shiny symbols of the future. It follows, therefore, that retaining the name of an old product for one of the biggest cement associations in the world might be considered unhelpful.

In some respects OPC and the PCA have become victims of their own success. Cement built the modern world and has become ubiquitous. So commonplace in most countries, in fact, that people outside of the building industry often fail to realise how crucial the stuff is. The tricky proposition for those marketing cement today is to somehow recognise the historical contribution that it has made to build our world whilst also conveying how it is changing to become more sustainable. Unfortunately for fans of OPC though this may mean dumping it from the name of the PCA.

US: Eagle Materials has outlined its climate change mitigation successes in its 2023 Sustainability Report. During 2023, the company increased its production of blended cement products, including Portland Limestone Cement (PLC). It commenced a major CO2 reduction study with the US Department of Energy, and established a Greenhouse Gas Reduction Team to explore new clean technologies. Eagle Materials says that it is currently working to increase the use of alternative fuels at three of its cement plants.

UK: Holcim subsidiary Aggregate Industries has commenced its construction of a cement blending plant and import hub on the River Thames at the Port of Tilbury in Essex. The facility also includes units for the production of reduced-CO₂ cement components, including ground granulated blast furnace slag (GGBFS) and construction demolition waste (CDW)-based materials. The Tilbury site has five loading heads and will help Aggregate Industries to maintain its continuous supply of conventional, reduced-CO₂ and circular cementitious materials to London and South East England.

Chief executive officer Dragan Maksimovic said “This important investment will further strengthen our position in the market, allowing us to drive our sustainability ambitions and lead the way in low carbon and circular building materials. The London and South East construction market has major regional projects on the horizon, and we are primed and ready to meet the region’s rising demand for sustainable solutions.”

Steve Curley, managing director cement, added “Our ECOPlanet range of green cement was recently added to our green offering. By investing in this impressive facility within the Port of Tilbury, we will truly boost our sustainable offering and be more agile and efficient in the way we manufacture, transport and supply our products across this region.”

Philippines: Holcim Philippines recorded sales of US$332m during the first nine months of 2023. This represents a 4% drop from nine-month 2022 levels. The producer reported operating earnings before interest and taxation (EBIT) of US$25.2m. Throughout the period, Holcim Philippines co-processed 800,000t of alternative fuel (AF) at its plants. Blended cement products ended September 2023 at 75% of its cement sales.

India: Ratings agency ICRA says that the cement industry in India will reach a renewable energy reliance of 40% across its operations in the 2025 financial year. The Hitavada newspaper has reported that this will involve the construction of 537MW-worth of new renewable power capacity. During the 2023 financial year, which ended on 31 March 2023, producers used 35% renewable energy. ICRA said that they can expect to make costs savings of US$240m/yr from 2025 through the scale-up of renewables, including solar, wind and waste heat recovery. This would correspond to a 15 – 18% reduction of estimated energy costs for the 2025 financial year.

Over the same two-year period, ICRA forecast blended cements to rise to 81% of cement sales in the 2025 financial year, from 78% in the 2023 financial year.

Germany: Dyckerhoff has launched Dyckerhoff Weiss Blue Star, a pozzolanic white cement CEM IV/A (P) 42.5 R product. It was approved by the German cement association, the VDZ, in mid-June 2023 and is now being manufactured at the Amöneburg plant. The lower CO₂ credentials of the new product have been promoted as it releases around 15% less CO₂ compared to CEM I cements. It is also notable for being a blended white cement.

Cement producers in Bangladesh received a surprise at the start of June 2023 when the government budget proposed increasing the duty on imported clinker. The Bangladesh Cement Manufacturers Association (BCMA) reacted this week by calling for the duty on clinker to be reduced, while also calling for the same for a non-adjustable advance income tax (AIT) applied to associated imports and sales.

During a press conference, reported upon by the Financial Express newspaper and other media, BCMA president Alamgir Kabir said that the customs duty on key raw materials for the sector had previously been around 5% of the import value. However, he argued that the new suggested increased tariff was “disproportionate” because it placed the burden at 12 - 13%. He urged the government to treat the cement sector as a "priority sector" given that it was facing higher prices generally due to the aftermath of the Covid-19 pandemic, the energy shocks from the Russian invasion of Ukraine and negative currency exchange effects.

The BCMA’s latest lobbying call may sound familiar because it follows a similar battle against import charges from late 2022. A supplementary duty was introduced in November 2022 when the National Board of Revenue (NBR) changed the way limestone was coded in response to a significant increase in imports from 2020. At the time, the price of limestone imports reportedly nearly doubled. The BCMA may have won this battle because in March 2023 the NBR withdrew its supplementary duty. It did require that importers submit to further scrutiny including an updated Import Registration Certificate and various tax related requirements.

The timing of the NBR’s decision to relax the limestone duty is telling given that the previous month or so six of the country’s seven publicly listed cement producers reported either falling profits or losses for the second half of 2022 or the year as a whole. Only LafargeHolcim Bangladesh bucked the trend with an increase year-on-year in its annual profit after tax in 2022, although it attributed this to 95% volume growth in its aggregates business.

As discussed previously a characteristic of the cement sector in Bangladesh is that the country has no domestic limestone reserves. It all has to be imported. Arusha Ahmed Khan, Shun Shing Group presented a summary of the national industry at the Global Slag Conference that took place in early June 2023 in Düsseldorf. The country has two integrated cement plants and 36 grinding mills operated by 31 companies with a total capacity of 84Mt/yr. At present around 14Mt/yr of new cement grinding production capacity is planned by UK Bangla Cement, MI Cement, Confidence Cement and Dubai Bangla with commissioning dates expected from mid-2023 to mid-2025. Khan revealed that the government switched from British to European standards in the early 2000s leading to a high level (95%) of blended cements on the market. Use of slag cements has grown as more producers commission vertical roller mills and more uptake of slag and other blended cements using secondary cementitious materials (SCM) is expected in the future.

A key vulnerability for a grinding-heavy cement sector, like the one in Bangladesh, is any burden on imports such as logistic costs, currency exchange effects and government tariffs. Sure enough each of these examples has been reported locally. The government says that its proposed higher import tariff on clinker is the first such change in a decade. Cement producers have reacted, predictably, in a negative manner. Whether the authorities go ahead with the planned increase and how well the cement sector could absorb it remains to be seen. There may never be a good time for a tax rise but the BCMA has been able to present the current period as being especially bad.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

US: Holcim subsidiary Geocycle has signed a multi-year contract with Louisville Gas and Electric and Kentucky Utilities to market fly ash produced by the power generation companies. Geocycle and Holcim will use to up to around 225,000t/yr of fly ash to produce blended cement products.

Sophie Wu, Head of Geocycle North America, said “In line with Geocycle’s commitment and passion for recycling and achieving a net zero future, we are honoured to partner with Louisville Gas and Electric and Kentucky Utilities to develop creative and efficient solutions that contribute to the circular economy.” She added, “Together we’ll be able develop blended cementitious materials, reduce CO₂ levels and further encourage carbon neutral construction.”

Canada: Lafarge Canada’s Brookfield plant in Nova Scotia has switched to Portland Limestone Cement (PLC) production. The unit will now manufacture the company’s OneCem PLC product. It is the cement producer’s third plant to transition to PLC production in 2022 following the Bath plant in Ontario and the Richmond plant in British Colombia.

Andrew Stewart, the Vice President of Cement at Lafarge Canada (East), said, “We have been steadily moving the needle forward when it comes to cement decarbonisation and we will continue to honour our commitment in progressing our greener portfolio in Eastern Canada over the coming years.”
