US: Cemex USA has upgraded two Florida cement terminals, the Pensacola and Palm Beach terminals, at a cost of US$8m. The upgraded terminals will serve to increase Cemex USA’s cement supply to the region through marine shipments from its global operations. The Palm Beach terminal is also involved in the distribution of assorted cementitious materials including granulated blast furnace slag (GBFS) and fly ash for cement production.

USA executive vice president Matthew Wild said “Florida is growing rapidly, and Cemex’s strong network makes our company well-positioned to implement supply chain and operational enhancements to meet the high demand for building materials in Florida and beyond.” He added “On the cement side, increased demand has outpaced supply at times, and we expect our supply chain enhancements to help alleviate that issue.”

Holcim Schweiz hit a milestone recently with the aerial drone programme at its Siggenthal cement plant. The project with Voliro, a Switzerland-based technology start-up, has started to use multi-rotor drones to conduct official measurement flights. They used them to take measurements to determine the steel wall thicknesses of the cement kiln and the cyclone preheater. The work has been part of Holcim’s ‘Plants of Tomorrow’ industrial automation plan with unmanned aerial vehicles (UAV). Key features of the particular drones being used are that they can be rotated around all axes by a special rotor system and can even fly upside down.

Holcim has been using drones in and around cement plants for a few years now. When it launched the Plants of Tomorrow plan in 2019, Switzerland-based drone supplier Flyability said that the cement company had chosen its Elios 2 model to perform confined space inspection. Earlier in 2017 another supplier, SenseFly, said that LafargeHolcim Tanzania had been using its fixed-wing products. Holcim is also far from alone in its use of drones. A few examples among many include Cemex USA’s work with Kespry earlier in 2021, HeidelbergCement’s work in North America and Germany in 2020 and 2021 and Votorantim’s testing at its Córdoba and Niebla plants in Spain back in late 2015. 

UAV usage by armed forces dates back to examples like unmanned incendiary balloons being deployed in the 19^th century to Azerbaijan’s reported decisive use of drones in its war against Armenia in late 2020. The current era of industrial UAVs began after 2000 when governments starting issuing civilian permits, miniaturisation occurred and improvements in cameras, sensors and computing power followed. For the mineral processing sector the trend started with drones being used for stockpile management and quarry surveying. At present this is the main area that UAVs are used for by the sector, often coupled with photogrammetry techniques. CalPortland’s Adam Chapman’s paper at the 2021 IEEE-IAS/PCA Virtual Cement Conference described one company’s use of UAVs in the cement industry since 2016, looking at licensing, cost, quality of data, drone technology, fleet management and field experiences.

More recently though, tests of drones used to survey cement plant buildings and structures have started being publicised such as Holcim’s work at Siggenthal. A presentation by consultant John Kline and Chris Place of Exelon Clearsight summarised the use of drones for structural inspection at cement plants at the Global CemProducer 3 webinar in January 2021. The key benefits they promoted of using an UAV in this way were: improved safety because workers have reduced risk from climbing, working at height or in confined spaces; less time to conduct a survey; higher resolution photographs and video; better coverage through grid method surveying; and an overall lower cost. However, on that last point, other commentators have noted that market-leading drones for surveying are relatively expensive and easy to damage. Drones have since been used to start going inside structures at cement plants with Kline demonstrating their use to inspect the condition of refractory within the cooler, kiln, pre-heater and cyclone of a production line at the Global CemProducer 2 webinar in July 2020. HeidelbergCement has also been doing similar things, with an inspection trial using a drone of the kiln at the Schelklingen plant in Germany during the 2021 maintenance shutdown period at the site.

So far the use of drones by the cement industry has mostly been in a surveying or inspection capacity. Given the short time that UAVs have been used like this there is likely to be scope for lots more development both within existing fields and new ones as the sector works out how best the technology can be used. One application we couldn’t find in the research for this short article was the use of drones for security and surveillance tasks at cement plants and quarries although this may be happening already. However, there could be a more active role for drones if or when a company finds a way for them to start making basic repairs or carrying out simple maintenance in those hard to reach areas that drones excel at accessing. Research examples exist of UAVs being used to spray concrete or repair materials onto minor defects in concrete structures. Yet considerable challenges face these kinds of applications such as the weight of a loaded multi-rotor drone or damage from rebound. Before we all get too worried about drones replacing our jobs though it is worth considering that Amazon’s plan to deliver packages by UAV was first announced in 2013 and it still hasn’t happened yet. It may yet, but for now in most situations humans remain cheaper and more practical than robots or drones.

US: Cemex USA has announced plans for an upcoming 600,000t/yr aggregates plant in Brierfield, Alabama. The Birmingham Business Journal newspaper has reported that, when operational, the plant will supply the company’s ready-mix concrete operations in the state. The subsidiary of Mexico-based Cemex operates 30 batching plants in Alabaster, Tuscaloosa and Vance.

Mid-South regional president Marc Tyson said “The Brierfield plant gives us a new opportunity to support our existing customers and earn the business of new ones by leveraging the wealth of experience of our team and providing them materials sourced from all parts of Cemex USA's supply chain.”

US: Cemex USA’s Victorville cement plant in California has won the Portland Cement Association (PCA)’s Chairman’s Safety Performance Award 2021 in the Large category. The award recognises top safety performance. The Victorville cement plant previously won the award in 2019 and 2020. Cemex USA says that the plant recorded zero incidents in 2020. Earlier in 2021, it surpassed four years without a lost time injury to any employee or contractor.

President Jaime Muguiro said “Safety is our top priority, and Victorville cement plant is demonstrating that Zero4Life is possible. We are proud of the continued commitment of our team, and their achievement is a great example of what can happen when everyone is dedicated to safety and works together to look out for one another.”

US: The Portland Cement Association (PCA) has received the 2021 Energy Star Partner of the Year award from the US Environmental Protection Agency and the US Department of Energy. It is the second year in a row the association has been recognised in this way. Each year, the Energy Star program recognises a group of businesses and organisations that have made outstanding contributions to protecting the environment through superior energy achievements.

“The PCA and its members are proud to be recognised for continuously improving energy efficiency to reduce emissions,” said PCA President and chief executive officer Michael Ireland. “The cement and concrete industry is leading the way towards a more sustainable future as PCA and its members are developing an industry roadmap across the entire value chain to reach carbon neutrality by 2050."

In addition to PCA’s Partner of the Year recognition, two PCA member companies, CalPortland and Cemex USA, earned corporate Partner of the Year awards and 13 US cement plants earned Energy Star certification for superior energy performance in 2020.

US: Cemex USA, part of Mexico-based Cemex, has won a contract to supply 90,700t of cement and 153,000m³ of concrete for the latest phase of construction of the Houston Grand Parkway. The cement and concrete will help build the road’s I-1 and I-2 sections. The ring road around Houston is the longest of its kind in the US. Cemex USA will provide a portable central mix plant for the project.

Texas regional president Scott Ducoff said “Cemex USA is proud to be part of an iconic infrastructure project in our headquarters city of Houston, and one that will help ease traffic and improve local travel for commuters.” He added “Completing the Grand Parkway is a significant endeavour and opportunity for us to continue to innovate how we efficiently and effectively deliver our best-in-class materials to meet the demands of inspiring projects such as this one.”

US: Kespry says that Cemex USA is using its drone and software product for stockpile management at its operations. A Cemex representative said that it has mapped 74,500ha of land over more than 4000 drone missions using Kespry’s product. The supplier uses autonomous aerial drones to gather survey data and then uses machine learning techniques to analyse the results.

Director of aggregate resources Matt Lewis said, “Kespry plays a critical role at both our cement and aggregates sites, despite operations being significantly different. Since initially adopting Kespry, we have been able to measure 21,100 stockpiles across our aggregates sites, while also collecting massive amounts of topographic data into the Kespry Cloud across our cement sites. The amount of time and money the Kespry platform has saved us is unmatched, and we wouldn’t be able to operate at this level if it weren’t for Kespry.”

US: Cemex USA has acquired Beck Readymix Concrete. The ready-mix producer operates three concrete plants in San Antonio, Texas and an additional portable plant.

Texas Regional President Scott Ducoff said, “Texas is experiencing explosive growth and Cemex has repeatedly shown it is ready to make moves to help fuel it. By acquiring these facilities, Cemex will be able to deliver our high-quality products that many Texans are already familiar with to satisfy the high demand of customers of one of the state’s most dynamic markets. We welcome our new employees and look forward to a smooth transition for them.”

US: The US Department of Energy has awarded a grant to Cemex USA, UK-based carbon capture and storage (CCS) specialist Carbon Clean and Oak Ridge National Laboratory. The grant covers the implementation of a CCS system at Cemex USA’s Victorville cement plant in California, in addition to the development of a commercially viable carbon utilisation solution. The producer says that the study is due to last 30 months.

President Jaime Muguiro said, “Cemex is committed to being part of the solution to reduce carbon emissions globally and to deliver net-zero CO₂ concrete to all of our customers by 2050. We cannot achieve these aims without innovative technology and collaborative relationships with both public and private organizations who share a commitment to climate action. This grant gives us an excellent opportunity to further develop a new technology to help us all reach our goals.”

Mexico/US: Cemex has invested US$15m in recommissioning a 1Mt/yr cement kiln at its CPN cement plant in Hermosilla, Sonora. The decision is intended to reduce cement shortages in the western US and bolster its supply chain in Arizona, California and Nevada. The project at the CPN plant is scheduled for completion in the second quarter of 2021 and will create 130 jobs.

Cemex USA cement commercial executive vice president Joel Galassini said, “Many cement customers in California, Arizona and Nevada have been impacted by supply constraints this past year. The decision to recommission this kiln was made with our customers top-of-mind, to give them reliable access through a local supply chain to help meet their growing needs. Our unique network of production facilities in this region allows us to make these types of investments that will have a meaningful impact on meeting our customers’ needs.”

California regional president Francisco Rivera said, “We are excited to build greater synergies with our Mexican operations to strengthen our US cement supply chain and help our customers avoid or mitigate any potential delays to their projects in 2021.”
