Ghana: A nine-member committee has been established to monitor and coordinate the local cement industry in Ghana, in line with the Manufacture of Cement Regulations (LI 2480).
The committee, inaugurated in Accra on 5 April 2024, is chaired by Professor Alex Dodoo of the Ghana Standards Authority (GSA). Other members include representatives from the GSA, Ministry of Trade and Industry, Ministry of Environment, Science, Technology and Innovation, Environmental Protection Agency, Ghana Institution of Engineering, Association of Ghana Industries, Chamber of Cement Manufacturers of Ghana, and an expert in cement production nominated by the Minister.
During the inauguration, Trade and Industry Minister Kobina Hammond said “The committee will appraise, evaluate and approve local content and local participation plans and reports of cement manufacturing entities. They will also promote the production, wholesale and retail of cement and cement components.”
According to LI 2480, there is a requirement for manufacturers of cement to register with the Committee. Regulation 11 in LI 2480 state that ‘A person shall not manufacture cement in the country unless the person registers with the Cement Manufacturing Development Committee in accordance with these Regulations.’ The regulations state that a person who did not register with the Cement Manufacturing Development Committee to manufacture cement shall not be granted a licence to manufacture cement under these regulations.
Ghana tightens cement standards
12 February 2024Ghana: The Ghana Standards Authority has enacted new quality standards for cement products. BNN Breaking News Ghana has reported that the new standards are intended to uphold safety for users of concrete buildings. This will reportedly be accompanied by increased enforcement against substandard products, including the roll-out of a new licensing system.
Managers arrested at Kumasi Cement Ghana
27 November 2023Ghana: Two managers at Kumasi Cement Ghana have been arrested by officials from the Economic and Organised Crime Office (EOCO) and the Ghana Standards Authority (GSA). Huang Guangshun and Fang Yuan were detained for continuing to operate the company despite being requested to stop, according to the Graphic newspaper. Samuel K Frimpong, the Ashanti Regional Manager of the GSA, said “They claimed to have been asked to keep producing by an unnamed top government official, but we acted per the law and got them arrested.”
Kumasi Cement Ghana, Xin An Safe Cement Ghana and Unicem Cement Ghana had their licences revoked by the GSA in mid-November 2023 for using inferior materials in cement production. The closure of the cement plants is part of a government strategy to stop the production of ‘substandard’ cement in the country.
Officials from Xin An Safe Cement Ghana and Unicem Cement Ghana have signed an agreement at the head office of the GSA to “adhere to specified quality standards in cement manufacturing”. They pledged to “comply with all regulatory standards and requirements governing cement manufacturing in Ghana.” However, the GSA is yet to allow the companies to restart their operations.
Ghana: The Ghana Standards Authority (GSA) has reported discoveries of Empire Cement brand cement on sale on the open market despite neither it nor the Ghana Environmental Protection Agency (EPA) having issued permits for Empire Cement to produce cement. Graphic Online News has reported that the suspect products are wrongly labelled with certification marks. GSA director general Alex Dodoo warned that this constitutes an offence.
Calcined clay projects in Africa
06 April 2022African cement producers have confirmed their interest in calcined clay over the last month with two new projects. The big one was announced last week when FLSmidth revealed that it had received an order from CBI Ghana. This follows the launch of a Limestone Calcined Clay (LC3) project in Malawi in mid-March 2022 in conjunction with Lafarge Cement Malawi.
FLSmidth says that its order includes the world’s largest gas suspension calciner system and a complete grinding station. The kit will be installed at CBI Ghana’s plant near Accra in the south of the country. The new clay calciner system is expected to substitute 30 - 40% of the clinker in the final product, resulting in a reduction of up to 40% CO2/t of blended cement compared to Ordinary Portland Cement (OPC). Overall the equipment manufacturers reckon that the grinding plant will reduce its CO2 emissions by 20% compared to its current output. There has been no indication of how much the order costs but CBI Ghana expects energy and fuel savings, as well as lower overheads from clinker imports.
The public announcement of the Ghana project was also foreshadowed by the visit of Professor Karen Scrivener to the Ghana Standards Authority in February 2022. This was significant because Scrivener is the head of the Laboratory of Construction Materials at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and has been one of the key instigators of the LC3 initiative since the early 2000s. Other calcined clay cements are available such as Futurecem or polysius activated clay (see below) but LC3 is arguably the most famous given its promotion in developing countries.
The Malawi project is at a much earlier stage. The government launched the public private partnership LC3 project in mid-March 2022 in conjunction with Lafarge Cement Malawi and Terrastone, a brick manufacturer. The Ministry of Mining is currently developing a memorandum of understanding with the Gesellschaft für Internationale Zusammenarbeit (GIZ), a Germany-based development agency. India-based Tara Engineering has also been linked to the scheme.
One thing to note about the Malawi project is that it is the first calcined clay project in the cement industry based in East Africa. All the other African ones are based in West Africa. The other two projects in this region are run by Turkey-based Oyak Çimento and its subsidiary Cimpor. The first of these is a 0.3Mt/yr calcined clay and a 2400t/day cement grinding production line that was commissioned in mid-2020. This plant is based at Abidjan in Ivory Coast. The second is a new plant that Germany-based ThyssenKrupp Industrial Solutions is building for Oyak Çimento at Kribi in Cameroon. This unit has a 720t/day calcined clay and a 2400t/day cement production capacity and it will use the supplier’s ‘polysius activated clay’ technology. ThyssenKrupp’s involvement came to light in early 2020 and commissioning was scheduled for late 2021. However, no update on the state of the project has been issued so far in 2022.
As the above examples show, Sub-Saharan Africa has at least one live calcined clay plant, two plants are being built and there’s one more at the development stage. This puts the region neck-and-neck with Europe, which has a similar mixture of current and developing projects. This column has been covering the wider trend of the growing usage of various types of blended cements recently, particularly in Europe and the US, with slag cements, Portland Limestone Cement (PLC) and more. With PLC, for example, note the transition of another two North American cement plants to PLC this week alone. As for calcined clay cement, it is fascinating to see the focus move to a different part of the world. Several commentators have predicted that the future looks set to be dominated by blended cements using whichever supplementary cementitious material (SCM) is most available for each plant. The growth in calcined clay confirms this view.

Professor Karen Scrivener promotes calcined clay production in Ghana
02 February 2022Ghana: Professor Karen Scrivener has paid a working visit to the Ghana Standards Authority (GSA). The visit was part of a tour by Scrivener to Ghana to discuss innovations in cement and cementitious products and to introduce Limestone Calcined Clay Cement (LC3) to the authority, according to the Ghana News Agency. The Head of Laboratory of Construction Materials at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland met with GSA management and staff of the Building and Civil Engineering Lab at the Authority's Head Office in Accra. Scrivener noted that she was interested in learning more and engaging with the GSA on standards and its testing capabilities as well as a potential collaboration in capacity building in cement and cementitious products.
Cement Manufacturers Association of Ghana calls for investigation into Chinese cement imports
19 October 2018Ghana: The Cement Manufacturers Association of Ghana (CMAG) has appealed to the Ghana Standards Authority (GSA) to investigate the quality of Chinese cement imports. In a letter of the GSA George Dawson-Ahmoah cited two companies in Tema and Ejisu that allegedly sell cement products of ‘questionable’ quality, according to the Business and Financial Times newspaper. He also posited that samples of cement from these companies were ‘alarming’ and that this explained why their prices were ‘ridiculously’ low.
CMAG consists of Ghacem Limited, Diamond Cement group, CIMAF Ghana and CBI Ghana Limited. However, when asked by the local media why Chinese companies supplying Ghana were not part of the association, Dawson-Ahmoah said that they had been invited.
Ghana Standards Authority to start large-scale cement inspection
31 October 2017Ghana: The Ghana Standards Authority (GSA) plans to start a large-scale market inspection on the sale of cement. It follows efforts by the GSA to stamp out poor standard goods in the market, according to Citi Business News. The initiative is also intended to protect consumers. It follows stories in the local media about building collapses due to poor quality cement.
