Natural pozzolan use in the US 03 July 2019
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.

Spain: FYM-HeidelbergCement plans to spend Euro3m on a new raw slate crusher at its integrated Malaga cement plant. The upgrade will replace two existing crushers and will improve dust and noise emissions. The new crusher will be installed in early 2020, with commissioning scheduled for the middle of the same year. No supplier for the equipment has been specified.
The plant is also about to launch a new clinker conveyor at the Port of Malaga. The enclosed system will deliver clinker from the dock to ships via a telescopic arm with a loading capacity of 650t/hr. The first boat to be loaded with the new system is scheduled for late July 2019. The project cost Euro2.5m.
Production stopped at Seongho Lee cement plant in North Korea due to lack of electricity 03 July 2019
North Korea: Production has reportedly been stopped for three months at the Seongho Lee cement plant near Pyongyang due to a lack of electricity. Sources quoted by South Korea based Daily NK online newspaper suggest that government power rationing has lowered the importance of the plant in comparison to other so-called ‘core’ industries.
The Korean Cement Association reported in 2011 that the plant had a production capacity of 0.95Mt and it uses a wet process production line. The site dates back to 1919 and the age of its equipment may have contributed to the decision to idle the plant.
Chile: The Servicio de Evaluación Ambiental (SEA), the country’s environmental body, has approved the environmental impact assessment for a new 0.5Mt/yr grinding plant that Melón is planning to build in Punta Arenas. The unit will have an investment of US$45m, according to the Diario Financiero newspaper. Spain’s Cemengal will supply the mill for the project.
India/UK: The Global Cement and Concrete Association (GCCA) has launched GCCA India. As part of GCCA’s strategic partnership with the World Business Council on Sustainable Development the new office, based in Mumbai, will take over the work of the Cement Sustainability Initiative (CSI) India, which formerly served as the sector’s sustainability alliance.
GCCA India plans to ensure that, from a sustainability angle, innovation in technology and manufacture, and collaboration across the wider built environment, the Indian cement sector can play a key leadership role. It will develop a work program that will focus on the wider global GCCA priorities but with practical application across the Indian built environment.
