Germany/Switzerland: LafargeHolcim has reportedly placed a bid for BASF Construction Chemicals, according to sources quoted by Bloomberg. The cement producer has reached the second round of the bidding processing, along with companies including Bain Capital, Cinven and Standard Industries. The auction of the subsidiary of BASF that produces admixtures, mortars and grouts is expected to reach as much as Euro3bn. LafargeHolcim chief executive officer (CEO Jan Jenisch said in May 2019 that the company is considering at least 10 bolt-on assets purchases for 2019.

North America: Humboldt Wedag, a subsidiary of Germany’s KHD, has concluded a non-binding letter of intent with an unnamed customer in North America. The letter of intent for the engineering, supply of equipment and structural steel as well as advisory services related to erection and commissioning covers a potential order volume of more than Euro100m. The customer and Humboldt Wedag intend to enter into negotiations with the aim of concluding a corresponding engineering and procurement contract. Most of KHD’s orders come from the cement sector.

India: Basant Kumar Birla, chairman of BK Birla Group, has died at the age of 98 in Mumbai. He is survived by his grandson Kumar Mangalam Birla, the head of Aditya Birla Group, the owner of UltraTech Cement, amongst many other family members, according to the Times of India.

Part of the influential Birla family of industrialists, Basant Kumar Birla originally started working at Kesoram Industries before turning the business into a conglomerate with concerns in cement, engineering, medium-density fibreboards, pulp and paper, rayon, shipping, tyres, tea, chemicals and other sectors. BK Birla Group reported a turnover of US$2.4bn in the 2018 – 2019 financial year. At present the group now comprises five major companies - Kesoram Industries, Century Textiles & Industries, Century Enka, Mangalam Cement and ECE Industries - and several smaller subsidiaries.

Charah Solutions has been steadily building up its fly ash distribution business in recent years with an eye on the supplementary cementitious materials (SCM) market. This week it opened the third of its new series of SCM grinding plants, at Oxnard in California, US. The unit sticks out because it is focusing on grinding natural pozzolans. The plant will receive natural pozzolan by truck and rail and then use Charah’s patented grinding technology to produce pozzolan marketed under its MultiPozz brand. The previous plants in this series mentioned natural pozzolans but this is the first to promote it explicitly.

The change is potentially telling because global demand for granulated blast furnace slag (GBFS) outstrips supply. Both performance benefits and environmental regulations are pushing this. It’s a similar situation for fly ash, also driven by trends to close coal-fired power stations in some countries. As Charles Zeynel of SCM trading firm ZAG International explained in the March 2019 issue of Global Cement Magazine, “...volcanic pozzolans are a potential SCM of the future. This is gaining traction, but it’s slow progress at the moment. This will be the answer for some users in some locations.”

The problem though is that natural pozzolans are down the list of preferred SCMs for their chemical properties after silica fume, GBFS and fly ash. The first is expensive but the latter two were traditionally cheap and easy to obtain if a cement or concrete producer had access to a source or a distribution network. Natural pozzolans are very much subject to variations in availability.

It’s no surprise then that Charah is promoting natural pozzolans in a Californian plant given that state’s environmental stance. It’s unclear where Charah is sourcing their pozzolan from but they are not the only company thinking about this in the US. Sunrise Resources, for example, is working on the environmental permits for a natural pozzolan mine near Tonopah in Nevada. As it described in its company presentation, California and Nevada are the most affected states in the fly ash supply crisis because they are, “...at the end of the line when it comes to rail deliveries from power stations in central and eastern USA.” It also estimated that California used 0.9Mt of pozzolan in its cement production of which about 90% is fly ash. The state produced 9.6Mt in 2015. Other companies are also mining and distributing natural pozzolans in the US as the website for the National Pozzolan Association (NPA) lists. Although, if this line-up is comprehensive, then the field is still fairly select. Most of these companies are based in the west of the country.

One last thing to consider is that various groups are tackling a potential future lack of SCMs for the cement industry by making their own pozzolanic materials through the use of calcined clay. These groups include the Swiss-government backed LC3 project and Cementir’s Futurecem products. Using clay should bypass the supply issues with natural pozzolans but the cost of calcining it requires at the very least an investment to get started.

As concrete enthusiasts often point out, a variant of pozzolanic concrete was used by the Romans to build many of their iconic structures, some of which survive to the present day. To give the last word to the NPA, “What is old is new again: natural pozzolan is back!” If environmental trends continue and steel and coal plants continue to be shut then it might just be right.

South Africa: PPC has appointed Roland van Wijnen as its chief executive officer (CEO). He succeeds Johan Claassen, who announced his retirement in November 2018. Van Wijnen has signed a four-year contract and is expected to take up the position as soon as he secures a work permit.

Van Wijnen has worked for Holcim and LafargeHolcim for 17 years in various leadership positions across the group including the CEO of Holcim Philippines. He also worked in South Africa for the business before it left the territory. He is an Industrial Engineering graduate from the University of Twente in the Netherlands.
