China: The board of directors of Anhui Conch have announced that Zhu Yuming has resigned as a supervisor of the company due to other work commitments. Zhu's resignation will be effective upon the appointment of a new supervisor to fill the vacancy. Anhui Conch have thanked Zhu for his 'invaluable' contributions to the company.

Germany: Hendrik Rahms will be supporting Loesche ThermoProzess GmbH (LTP) in technical sales and in the product development of thermal applications. After working as a process engineer and project manager for several years at Brinkmann Industrielle Feuerungs-Systeme GmbH, Rahms is very familiar with the products of burner and process technology as well as the customer requirements in the industry.

Nigeria: Lafarge Africa has notified the Nigerian Stock Exchange of the appointment of Adepeju Adebajo and Anders Kristiansson to the board of Lafarge Africa. Both staff members were formally appointed on 27 October 2014.

Adebajo is currently the MD of WAPCO operations. Prior to this, she served as the Chief Executive Officer and Managing Director at Mouka Limited. She was already the CEO of UTC Nigeria Plc, where she successfully turned the business around.

She previously headed strategic planning, brand management and product development at the United Bank for Africa and has had management consulting experience at Boston Consulting Group in the UK and financial analysis experience at Citibank in the UK.

Peju holds a Bachelor of Engineering (Chemical Engineering) from the Imperial College of Science & Technology, London; a Master of Engineering (Chemical Engineering) from the University of London; and a Master of Business Administration, Harvard University, Boston.

Anders Kristiansson is a Swedish citizen who started his career with Procter & Gamble (P&G) in Scandinavia and thereafter worked for P&G in South Africa. He has been a Global Divisional Controller for Eaton Automotive working in Europe and North America, whereafter he returned to Africa to oversee Celtel's finance departments across its African operations as Director of Financial Operations.

He moved to Nigeria in 2008 as Group CFO for PZ Cussons Nigeria, managing Finance and IT for PZ's five Nigerian companies. Prior to joining Lafarge, he was the CFO for NBC/Coca-Cola HBC's operations in Nigeria.

He holds a Master of Science Degree in Business Administration and Economics from the Gothenburg University, Sweden.

Lafarge's third quarter financial results have coincided with the alarming news that terrorists attacked one of its cement plants in Nigeria. Thankfully nobody was hurt at the Ashaka plant. The suspected Boko Haram insurgents reportedly came looking for French nationals but the plant had been mostly evacuated following an earlier more violent incident at a nearby town. Instead they stole explosives and trucks and fled.

The resonance here with Lafarge's global financial situation is that rebel action elsewhere in the world was noted as having an adverse effect on the cement producer's coffers for the third quarter of 2013. In Iraq cement volumes have reportedly fallen by 15% in the year-to-date and almost halved in the third quarter, hit by an inability to transport cement across the country since June 2014, when Islamic State fighters captured parts of northern Iraq.

Looking at the nine months so far in 2014, Lafarge's sales have fallen by varying amounts with the exception of one territory: Middle East and Africa. Here, bucking the trend, sales rose by 3% to Euro2.8bn. The area had been the group's single largest sales region so far in 2014. Of course countries such as a South Africa are much more stable, but most other countries in the territory have had recent terrorism campaigns where a European-backed cement plant might present itself as a target.

This is not good news for a corporate balance sheet relying on these same countries to keep the profits up. However, as Lafarge states in its outlook, 'emerging markets continue to be the main driver of demand and Lafarge will benefit from its well-balanced geographic spread of high quality assets.' Spreading its bets geographically should pay off.

Also in its outlook, Lafarge announced that it intends to pause its stand-alone divestments pending completion of the planned merger with Holcim. The move suggests that the company is prioritising the impending merger over debt reduction. With Lafarge's and Holcim's recent formal notification to the European Commission of their proposed merger to obtain regulatory approval, the last of its necessary notifications worldwide, the merger is getting closer. So far, the original expectation of closure in the first half of 2015 does not look unreasonable.

When former British prime minister Harold Macmillian was asked what causes governments trouble, his apocryphal reply was, "Events, dear boy, events." The same applies to building materials producers. There may be more 'events' before the merger completes.

The 'revelation' this week that South Korean cement producers have been paid US$127m to use/dispose of Japanese coal that is thought to be radioactive certainly sounds scary. If it is true that cement made with contaminated coal has led to the construction of radioactive buildings and roads, this may have prised open a 'can of worms' for coal producers, exporters and cement players alike. According to local media, four South Korean firms - Ssangyong Cement, Tongyang Cement, Lafarge Halla Cement and Hanil Cement - received the money to use the coal between March 2011, when the Fukashima nuclear power plant started to leak radiation, until 2013. A total of 3.7Mt of cement is 'under suspicion.'

Caesium-137 is formed by fission reactions that start with uranium-235 in nuclear reactors. The Fukushima reactor that started leaking in 2011 used this type of fuel. Once it leaked, caesium-137 was deposited into the sea and onto the land, presumably also making its way into nearby coal deposits.

As it is a metal with a melting point of just 28.5°C and a boiling point of 671°C, the caesium-137 would vaporise if it were to enter a cement production line operating at 1450°C as a metal. However, caesium will not enter the cement-making process as a metal due to its rapid and explosive reaction with water. An interesting slow-motion of this reaction can be seen here.

Instead, caesium will enter the cement-making process either as its oxide or a simple salt (e.g.: caesium chloride) in the coal. The salt will be ionized in the heat of the flame, sending caesium ions into the kiln and thus direct contact with the clinker as it is being formed. Here it will become part of the matrix of the clinker and hence the final cement product. All the time the caesium-137 is radioactive.

And it stays radioactive once it is in the finished product, for example in a building or road surface. Its half-life, the time that it takes for half of the caesium-137 to decay to meta-stable barium-137 (emitting radiation as it decays), is unfortunately very well matched to the life-span of concrete buildings at 30.7 years. This means that after about 100 years of building life the building would still be around 10% as radioactive as it was when it was built.

This would certainly be a problem if the coal was highly contaminated. However, a few questions come to mind. Firstly, if the coal contains 20-73 becquerels per kilogramme (Bq/kg) of caesium-137, as has been claimed by Lee In-young, an opposition spokesman for the New Politics Alliance for Democracy party and member of the National Assembly's Environment Labour Committee, why is this a problem when the Japanese legal limit for eating caesium-137 in contaminated vegetables is all the way up at 500Bq/kg? When the most dangerous mechanisms of caesium-137 poisoning relate to accumulation in soft tissue, how can driving along a caesium-137-containing highway constitute a health risk?

Also, the coal may well start the cement making process with 25-73Bq/kg of caesium-137 but the clinker will have a lower level. This is because for every 1t of clinker the plant will typically consume just 100-200kg of coal. The caseium-137 and hence the radiation will therefore be spread out over a larger mass. A level of 50Bq/kg in the coal would translate to a clinker level of 5-10Bq/kg. This is around 100 times lower than the Japanese vegetable limit. After this, the clinker is extended with additives to make cement. This is then added to aggregates and / or sand when concrete or mortars are made, further diluting the caesium-137, perhaps to as low as 1-5Bq/kg. It is arguable that South Korea has received a higher caesium-137 dose from Japan via air and sea than via coal imports.

In light of all this, it appears that those calling for investigations on scientific grounds, like Lee, may be misguided. However, there may be political gain. The histories of Japan and South Korea are long, violent and distrustful. Indeed, according to a BBC World Service poll conducted earlier in 2014, South Korea and China jointly have the most negative perceptions of Japan of all world nations. In this environment stories about radioactive coal become much easier to believe in.

In reality the Japanese vegetable limit is well above the likely levels that might be found in any cement products resulting from the use of this coal. It is consistent with EU limits set more than 20 years earlier (600Bq/kg). A search on the US Environmental Protection Agency's website fails to bring up any formal limit. Instead it states that everyone is exposed to caesium-137 from atmospheric fallout to a low level and that the most dangerous cases are where waste metal processors unwittingly come across sources.

So on the surface then, the South Korean reaction seems like a storm in a teacup. One question remains though. If the caesium-137 levels in the coal are so much lower than the Japanese vegetable limit, why are Korean firms being paid to take it out of Japan?
