France: Fives has secured a contract to supply a 65MW Pillard NOVAFLAM Evolution burner to a cement producer. The customer’s aims are to continue to maximise alternative fuel (AF) use, to improve clinker quality and to reduce NO_x emissions at its cement plant. The order also includes precalciner burners and a natural gas-powered 35MW Pillard hot gas generator, as well as valve trains and pumping systems.

Ghana: The Ghana Standards Authority (GSA) has reported discoveries of Empire Cement brand cement on sale on the open market despite neither it nor the Ghana Environmental Protection Agency (EPA) having issued permits for Empire Cement to produce cement. Graphic Online News has reported that the suspect products are wrongly labelled with certification marks. GSA director general Alex Dodoo warned that this constitutes an offence.

Mexico: 200 police officers in 80 police cars arrived outside the gates of Cooperativa La Cruz Azul’s Cruz Azul cement plant in Tula, Hidalgo, on 15 December 2021, but failed to enter the plant. The El Financiero newspaper has reported that the police were following a court order to remove the company from the plant. Supervisory board president Alberto Lopez reasserted the company’s right to occupy the property in line with federal government ordinances. Lopez suggested an alleged collusion between cooperativists and Omar Fayad’s Institutional Revolutionary Party (PRI) Hidalgo state government to decieve the courts.

Authorities have frozen Cooperativa La Cruz Azul’s accounts with outstanding bills of US$800,000 in electricity, gas, equipment and services bills, as well as the payroll of its 1100 workers.

Coopertiva La Cruz Azul chair Federico Sarabia said that the developments threaten the existence of the Cruz Azul plant. He said "In terms of quality, Cruz Azul’s cement exceeds the standard. At the time that Cruz Azul disappears as a cement producer, prices will increase.”

North Korea: Manpho cement plant has increased its production capacity by 20% through ‘technical innovations.’ Korean News Service has reported that the installation of new equipment in the plant’s kiln line also improved clinker quality.

Japan: Rigaku Corporation has launched its new MiniFlex XpC high-throughput rapid x-ray diffractometer (XRD) for analysis of cement samples. The supplier says that the product is able to quickly identify variations in cement’s composition. It uses an EasyX interface and can be automated using a sample-loading robot or conveyor belt.

President and chief executive officer Toshiyuki Ikeda said “The MiniFlex XpC is a manufacturing-optimised powder diffractometer for fast and accurate quality control measurements. Using the latest developments and lessons learned from class-leading products like the Rigaku SmartLab, this compact XRD offers unrivalled performance and ease-of-use.”

Morocco: The government of Morocco has tightened cement and clinker quality standards. The Le Matin newspaper has reported that the new standards will see cement and clinker assessed on the basis of higher consistency and final product durability standards than previously.

US: ForneyVault has partnered with Command Alkon to improve the quality control process for a mutual customer, Titan Virginia Ready-Mix. The concrete producer, a subsidiary of Greece-based Titan Group, previously relied on both suppliers’ products separately. Now, ForneyVault has integrated Command Alkon ‘s quality control technology into its own data collection software. It says that the integration will benefit the concrete producer’s testing capabilities. Titan Virginia uses Command Alkon’s CommandQC software product to validate the quality for its own internal ready-mix concrete products.

Command Alkon software product owner James Shilstone said “Forney’s decision to place their data in the cloud makes it easy to interface with CommandQC. Sharing data between the two programmes eliminates the need for double entry and makes the test results available to the QC manager more quickly.” ForneyVault vice president, platform development Scott Grumski added “Integration with Command Alkon’s software allows Titan’s quality control technician to lose the clipboard and pencil... The integration partnership reduces risk and advances compliance for Titan’s quality assurance programme.”

Brazil/Turkey: Brazil-based Votorantim Cimentos has implemented artificial intelligence techniques for cement strength testing across 27 of its laboratories in Brazil and Turkey. The producer says that the technology gives precise cement strength readings after just three days, compared to 28 days without the technology. It also uses a new metric, technical efficiency, to measure cement’s performance in concrete from the customer’s point of view. The implementation has increased available test results by 200% and eliminated 119 hours of testing time in Brazil alone for the company. It says that this has increased its agility in dealing with quality control and customer satisfaction.

The company said, “We at Votorantim Cimentos want to pave the way for the future of civil construction in a simple, agile and sustainable way, strengthening our role at the construction site, working to be the first choice of retailers and consolidating ourselves as a reference in sustainability in the value chain. Therefore, we look at our research and development projects as short, medium and long-term initiatives to leverage innovations in the sector. Many initiatives are aimed at optimising internal processes that impact the performance of our products, such as those involving the use of artificial intelligence to develop applications and predictive models. In addition, based on models for predicting the properties of cements, we have already created others for use in our mortars and concretes."

Philippines: CRH and Aboitiz Equity Ventures subsidiary Republic Cement and Building Materials plans to roll out a quality control system to detect product quality across all of its cement plants by 2022. Business World News has reported that the company currently uses data science-based techniques at three sites. It says that it uses the method to predict the 28-day compressive strength without moulding and curing of a batch of cement.

Manufacturing vice president Lloyd Vicente said that with accurate predictions, “our operations can make it quick and precise adjustments to our recipe and other operating parameters, therefore reducing our CO₂ emissions.”

Guatemala: Local cement producers have expressed concern over the quality of rising imports from Asia. Issues over quality standards and packaging have been raised, according to the El Periódico newspaper. According to data from the Bank of Guatamala, cement imports worth around US$57m were reported in the first 11 months of 2020. Imports from Turkey and Vietnam represented 85% of this. The country has a cement production capacity of 5.5Mt/yr and domestic consumption is around 3Mt/yr.
