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.

Philippines: The Department of Trade and Industry (DTI) plans to establish a new cement testing facility. The Philippine News Agency has reported that the department has made an allocation in its 2021 budget for the facility.

DTI Bureau of Product Standards (BPS) Catajay said “For setting up a testing facility for cement by BPS, our target is to finish within the first half of 2021. Our procurement of equipment is on-going, so that we can conduct testing in the third quarter of 2021.”

The Philippines presently has two cement testing facilities.

El Salvador: LafargeHolcim subsidiary Holcim El Salvador has announced an alteration to the composition of its flagship product, Cuscatlán cement, developed in laboratories in France and Mexico. Strategic marketing manager Amalia Palacios said, “The new formula offers the end user higher quality and less waste, that is to say a yield of around 20% more for the same price, so that we are improving quality without an impact on the customer's pocket."

Turkmenistan: Cabinet of Ministers’ Deputy Chair Shamuhammet Durdylyev has announced plans for the country to produce a new grade of cement. Turkmenpor News has reported that the cement, designated 500-G20-K, will contain basalt porphyries. Durdylyev has said that the Ufra deposit in the Balkan region of western Turkmenistan will supply the basalt porphyries, adding, “These mineral substances significantly improve the quality of cement.”

The move’s aim is reportedly to boost Turkmen cement plants’ productivity without increasing the reliance on imports.

South Africa: PPC has reported that it has invested US$548,000 in the construction and installation of a pneumatic offloading facility including a 250t silo at its George Depot cement terminal in the Western Cape. The company said that this ‘allows the business to receive cement by rail, improving its turnaround to customers without compromising quality.’

Ghana: The Department of Trade and Industry has declared a moratorium on the construction of new cement plants in response to a cement surplus on the domestic market. Chamber of Cement Manufacturers executive secretary George Dawson-Ahmoah said that consumption stands at 6.5Mt/yr nationally. Ghana’s eight producers are utilising 50% of an total installed capacity of 12Mt/yr, according to All Africa News. “The government is investigating measures to prevent imports,” said Carlos Kingsley Ahenkorah, Deputy Minister of Trade and Industry. This may involve cement quality certification by the Ghana Standard authority.

South Africa: Morag Evans, the chief executive officer (CEO) of Databuild, says that local cement manufacturers are being ‘severely’ undermined by cheap imports from countries such as China, Vietnam and Pakistan. She adds that the government’s failure to stem the influx of these products could have a severe detrimental impact on an already struggling industry.

“In an industry already in the grips of a severe downturn owing to the decline in infrastructure development, not only are these imports negatively impacting the competitiveness of our local manufacturers, but independent studies have shown the quality of these international products to be inferior,” said Evans.

She also cited quality concerns with imported cement mentioning a study conducted by local manufacturer PPC. It found that, from 14 products tested from 10 different producers, most were either over or underweight and were also of inconsistent quality.

Evans has supported the Concrete Institute’s lobbying for a 45% import tariff on cement imports. However, she acknowledges that such a move could raise the price of cement and increase inflation in the general economy.

Databuild provides information about the construction industry in South Africa.

Nepal: A large number of cement plants are reported to have violated standard manufacturing practices and are selling products that are not up to international standards, according to the Nepal Bureau of Standards and Metrology.

The national standards body said that 25% of factories were producing sub-standard products, based on the tests of samples and market inspections conducted in the last fiscal year that ended in mid-July 2019. Some of the larger manufacturers included in the 25% were Hongshi Shivam Cement, CG Cement and Arghakhanchi Cement. A further 14 smaller suppliers were also included.
