Rai Group fighting sale of ARM Cement 04 September 2019
Kenya: Rai Group must pay a guarantee of US$62.6m to forestall the sale of Athi River Mining (ARM) Cement. The Kenyan financial services company, owned by Jaswant Rai, is backing a claim by Pradeep Paunrana against PricewaterhouseCoopers over its administration of the sale of the publically-owned ARM Cement. Paunrana, erstwhile majority shareholder and managing director of ARM Cement, is contesting the cement company’s sale in May 2019 to Nairobi Cement, a subsidiary of Devki Group, for US$48.2m including a deposit of US$9.62m. Paunrana argues that the sale was unfair because ARM Cement was misvalued, having missed opportunities to sell its fertiliser and mineral production businesses due to pressures from potential buyers. Business Daily has reported that Paunrana previously submitted an unsuccessful bid in consortium with Rai Group to buy back the company for US$62.6m, also May 2019.
LafargeHolcim lobbies Madagascan government on imports 04 September 2019
Madagascar: LafargeHolcim has lobbied for cement homologisation norms to targeting importers. Chief Executive Officer François de Lesquen said that the company does not fear competition but wants a level playing field.

Conifers indicate cement plant’s carbon footprint 04 September 2019
China: Research conducted by the North-West Institute of Eco-Environment and Resources has ascertained detailed data on carbon dioxide (CO2) and mercury (Hg) output at a cement plant in Lanzhou using local spruces.
VerticalNews has reported of distance-dependent variations of Hg concentration in needles close to the cement plant, with the highest concentrations observed in needle samples from the site nearest to the plant. Hg in tree rings increased gradually for all sites by year, reaching a concentration of 65.8ng/g in the last growing period at 0m from the plant.
The study fuels hopes of accurate quantification of historical accumulation of air pollutants, including heavy metals, as well as contributing to our understanding of biochemical Hg cycling in forest ecosystems.

Iraq: Pakistan’s Attock Cement has begun commercial operation of its Basra grinding plant. The 0.9Mt/yr unit was commissioned in April 2019.
Caribbean Cement exports clinker to Haiti 03 September 2019
Haiti: Jamaica’s Caribbean Cement has begun exporting clinker to Haiti. The Jamaica Observer reports that the first shipment of 7500t of clinker was of surplus material from the company’s 1.3Mt/yr Rockfort Plant. The plant has received US$162m in capital expenditure since 30 June 2015.
Cemex divests itself of Euro300m Spanish assets 02 September 2019
Spain: Following its 2018 appeal against a Euro445m fine for misreporting losses, granted on condition of the company paying the court Euro300m in line with its obtaining specified mortgages and land sales, Cemex continues to release its holdings on the Iberian peninsula.
Cinco Días has reported that Cemex’s Spain operations closed its sale to Turkey’s Çimsa of its White Cement division in the first quarter of 2019 for 180 million. In 2018, the Spanish subsidiary of Cemex divested itself of five pieces of property at a profit of Euro17,000. Its Azuara production line in Saragossa Province generated capital gains of Euro462,000.
In the first half of 2019, Cemex reported earnings before interest, taxes, depreciation and amortisation (EBITDA) in Europe of Euro185m, up by 21% from US$168m in the same period of 2018.
Cemex’s Spanish presence began in 1992, when it acquired the country’s two largest cement companies, and it was hit by the downturn of 2008. La Nueva España reports that Cemex has applied for concessions from the Port of Gijón for storage of a dissembled biomass fuel hopper which had been awaiting shipment to Cemex’s Tilbury plant when the recession struck, grounding it in the the port, where it has remained ever since. Autoridad Portuaria de Gijón, the administrative body responsible, is currently considering Cemex’s application.
University of Dundee study looks at fly ash moisture 02 September 2019
UK: A study by the University of Dundee has dispelled the myths of substantial performance differences between concretes made with cement containing dry or wet-stored fly ash, with comparable reinforcement corrosion between the two.
Vertical News has reported that the research, whose backers included the Department for Environment, Food & Rural Affairs and Heathrow Airport Holdings, was aimed at “quantifying moisture effects, which indicate agglomeration of fly ash and a tendency for this to increase with free lime content, storage period and temperature.”
Researchers tested five moistened fly ashes and samples from two power station stockpiles, and further investigated different material and storage variables, comparing the concretes at 75mm slump and 28 day strength. Air permeability and water absorption of moistened fly ash proved greater with high free lime (up to 0.9%) and lower with low free lime (to under 0.1%). What benefits there were improved with longer storage. The moistening of low-free-lime fly ash generally yielded similar, or slightly higher, carbonation and chlorine diffusion. The moisture caused little change in high-free-lime ash’s carbonation, while increasing chloride diffusion. Furthermore, high storage temperature equated to greater carbonation.
In spite of these intriguing chemical differences, the study concluded, "these didn't seem to have a noticeable effect on concrete resistance.”
Ramco Cement set to boost capacity 02 September 2019
India: Ramco Cement is set to complete its expansion works, aimed at raising total production capacity to 20Mt/yr from 12.5Mt/yr, by the end of 2020.
