US: Holcim has completed a major expansion of its cement holding facility in North Fremont, allowing the plant to meet ‘growing’ market demands in the Omaha region. The US$20m project includes additional rail capacity, a new 50,000t cement dome, an extra silo and a blender for product mixing.

According to the company, the facility now employs seven staff members, up from three, and fulfils the Nebraska Department of Transportation's blended cement requirements using natural pozzolan to create a lower-carbon product.

Holcim's head of US Corporate Communications, Lynn Safranek, said "The availability of extra cement storage and the addition of rail capacity means fewer trips to transport cement from Holcim’s plant in Ste. Genevieve, Missouri, and more reliance on train transportation, which is more efficient than other land-based alternatives.”

US: Holcim US has announced an investment of US$20.5m in its Midwest operations. A key component of the investment is the new 35m-high cement storage dome in Fremont, Nebraska, which will increase its production capacity of ECOPlanet low-carbon cement. The dome has the capacity to store 50,000t of cement. Construction of the dome, which began in 2021, has contributed to local economic development and job creation at the terminal.

In line with the Nebraska Department of Transportation's blended cement requirement, the cement blended and distributed at the terminal incorporates natural pozzolan, a binding agent, to produce a lower carbon product compared to ordinary Portland cement.

US: The Portland Cement Association (PCA) has announced the winners of the 2020 Safety Innovation Awards. The awards recognise ‘creative safety-enhancing projects in the cement industry’ across five categories.

Buzzi Unicem USA’s Joliet, Illinois cement terminal won the distribution award for its barge entry ladder, which reduced fall hazards associated with unloading cement from barges. Ash Grove Cement’s Durkee, Oregon cement plant won the general facility award for its burner pipes cart upgrade, which reduced safety hazards associated with moving cement kiln burner pipes. Further hazard reductions were made by Buzzi Unicem USA’s Chattanooga, Tennessee cement plant’s finish mill access platform and the Monarch Cement Company’s Humboldt, Kansas cement plant’s noise reduction upgrade, which jointly won the milling/grinding award. The pyroprocessing award went to GCC of America’s Pueblo, Colorado plant for its semi-automated clinker feeding system, while the quarry award went to Ash Grove Cement’s Louisville, Nebraska plant for its dump box hardened material extraction tool.

PCA president and chief executive officer (CEO) Michael Ireland said, “Our industry prioritises the safety of its employees above all else. We are proud of our members’ efforts to pursue excellence in safety innovation for their company and their colleagues.”

World: FCT Combustion has released details on new burner projects it is involved with. Selected projects include a new contract in the US to convert both kilns to natural gas firing at Ash Grove Cement’s Louisville plant in Nebraska. The order includes Gyro-Therm MKII Burners, Natural Valve Trains and NFPA 86 BMS for both kilns.

Nova Cimangola in Angola has contracted FCT to convert its 5000t/day kiln to fuel oil firing. The order includes a multi fuel main burner, calciner burners, oil heating units, oil pumping and filtering units and control panels.

FCT also provided details about a low NO_x kiln conversion for an undisclosed client. Other selected cement sector projects include the commissioning of Turbu-Flex burner systems for clinker kilns at Finnsementti’s Parainen and Lappeenranta plants in Finland. These are scheduled for commissioning in March 2019 and April 2019 respectively. Baumit’s Wopfing plant in Austria is due for a natural has lance for kiln preheating to be delivered later in March 2019.

It also plans to deliver a Turbu-Flex burner system for a clinker kiln to an undisclosed client in China later in March 2019. It is based on a computational fluid dynamics (CFD) study undertaken by FCT is to allow for the firing of natural gas and to modernise the plant. Commissioning is scheduled for March 2019.

US: The Federal Trade Commission (FTC) has approved a final order settling changes for Ireland’s CRH acquisition of Ash Grove Cement following a period for public comment. The FTC issued its consent for the transaction in June 2018 on the condition that CRH sell the Three Forks cement plant in Montana to Mexico’s Grupo Cementos de Chihuahua (GCC).

Also under the settlement, because the CRH cement plant in Montana currently sells a significant amount of cement into Canada through two CRH terminals in Alberta, GCC will have the option to use those terminals for three years. CRH also has agreed to purchase, at GCC’s option, cement produced at the plant for distribution in Canada for up to three years. The FTC also forced CRH to sell other assets in Montana, Nebraska and Kansas.

US: The Federal Trade Commission has forced CRH to sell the Three Forks cement plant in Montana as part of its proposed acquisition of Ash Grove Cement. The plant and its quarry will be sold to Mexico’s Grupo Cementos de Chihuahua (GCC). Also under the settlement, because the CRH cement plant in Montana currently sells a significant amount of cement into Canada through two CRH terminals in Alberta, GCC will have the option to use those terminals for three years. CRH also has agreed to purchase, at GCC’s option, cement produced at the plant for distribution in Canada for up to three years.

The commissions ruled that the acquisition would harm competition in Montana, Nebraska and Kansas. Other divestments the Irish building materials company has agreed to include selling two sand-and-gravel plants, one sand-and-gravel pit, three limestone quarries and two hot-mix asphalt plants.

Following the agreed divestments, the FTC has issued its consent for CRH’s proposed acquisition of Ash Grove Cement. No further regulatory approvals are now outstanding for the transaction. The acquisition is expected to complete in June 2018. Ireland’s CRH agreed to buy Ash Grove Cement for US$3.5bn in mid-2017.

US: The Portland Cement Association (PCA) has announced the winners of the 2018 Safety Innovation Awards. The awards recognise creative safety-enhancing projects in the cement industry. Winners were determined by a panel of judges that evaluated submissions from across the country for milling/grinding, distribution, pyroprocessing and general facility.

Cemex USA’s Miami plant Florida won the milling/grinding category with its new process to load ball mills. The site developed a new mill loading process that uses a small hopper for grinding media, and an incline transport system with buckets to convey the grinding media directly to the mill. This new system eliminates the interaction between the employee and the machine, reduces the number of people needed to load the mill from five to two, and eliminates the need for employees to stand on top of the mill. This new system also improves mill loading rates from seven drums/hr to 30 drums/hr.

Cemex USA’s Houston operations in Texas won the pyroprocessing category for it use of drones for hazardous inspections. It has implemented a system for using protected air drones to inspect enclosed and confined spaces. Visual inspections of enclosed areas (preheater towers, tanks, silos, process ducts, etc) normally require intrusive equipment, long delays for system cooling, and placement of employees on scaffolding in confined spaces. These drones utilise an outer protective cage to minimize the risk of breakage due to impact. The drone program has eliminated the risk of putting staff in confined spaces, reduced the cost of scaffolding, and reduced the overall time for inspections.

LafargeHolcim US’ Corporate Program in Chicago won the distribution category for its X-Factor barge cover. It has developed a process for barge cover removal that reduces the risk of falls from employees stepping on to the barge. The X-Factor barge cover, developed over the last three years with a contractor, uses the latest technology and a no-touch design to allow a crane operator to perform all functions associated with barge lid handling without additional human assistance. Barge workers will no longer be required to step onto the barge to remove or replace barge covers, eliminating a potential fall risk.

Ash Grove Cement’s Louisville plant in Nebraska won the general facility category for its use of magnets as duct hole patches. Ash Grove has developed a hole-patch technique using magnets. Magnetic patches are quick, simple, and effective at preventing or limiting the release of materials from holes created in ducts caused by abrasion, leading to a cleaner plant, reduced slip, trip and fall risks, and fewer related Mine Safety and Health Administration housekeeping citations.

Cemex USA’s Brooksville in Florida also won the general facility category for its filters moved to ground level project. It redesigned the blower housings to move the filter from the top of the blower housings to an easily accessible location at ground level. The redesigned blower housing eliminates the need for employees to climb up and down a ladder, reducing overexertion and fall hazard.
