Armenia: The government has extended a temporary ban on imports of cement until the end of June 2024. The government says that the measure will help to re-establish competition between local cement producers and importers. NEWS.am has reported that Armenia produced 965,000t of cement during the first 10 months of 2023, up by 20% year-on-year. Meanwhile, in the first nine months of the year, cement imports grew by a factor of five, to 173,000t. Imports of clinker also rose, by 33% to 97,700t. The government attributed the growth of imports to rising cement demand and prices in Armenia during 2023.

Armenia: The tariff on cement imports has been reduced by 35% to US$22/t, from US$34/t previously, following changes to import rules by the government. Imports of clinker will be subject to no tariffs.

News.am has reported that seven-month cement imports to Armenia rose by 1.7% year-on-year in the period up to 31 August 2022, to 84.7Mt from 83Mt. The cause of the growth is variously the cancellation of an income tax refund on mortgages from 1 July 2022, the increased immigration of Russian citizens into Armenia and the growth of tourism.

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.

Armenia: The Armenian parliament has agreed to establish a customs duty of Euro22/t for cement and Euro3/t for clinker on imports from Iran and other countries. The government had initially hoped to imposed Euro39/t and Euro14/t on cement and clinker respectively but this was declined by the legislative body, according to the ArmInfo News Agency. Imported cement will also be recognised as licensed. The new bill will come into effect in July 2021.

A previous customs duty of Euro22/t imports of Iranian cement was set up in mid-2019. However, Iranian cement imports were then banned at the start of 2021. Production by local producers grew in 2020 and imports fell.

Iran: Cement production rose by 14.4% year-on-year to 35.6Mt in the first half of the local calendar year that started in March 2020 from 31.1Mt in the same period in the previous year. The sector exported 5.8Mt of cement with a value of US$128m to 28 countries according to the Mehr News Agency. India, Afghanistan, Russia, Iraq, Qatar, Kenya, Kuwait, Sri Lanka, Pakistan, Armenia, Turkmenistan, Kazakhstan, Azerbaijan, Bangladesh, China and Oman were among the export destinations of cement.

Iran: Data from the Islamic Republic of Iran Customs Administration (IRICA) shows that cement producers exported 5.85Mt of cement in the first five months of the local 2021 financial year, which began on 20 March 2020. The value of cement exports fell by 52% year-on-year to US$128m from US$266m, according to the Tehran Times newspaper. Iraq, Kuwait and Afghanistan were the top destination for the exports. Cement was also sent to India, Russia, Qatar, Kenya, Sri Lanka, Pakistan, Armenia, Turkmenistan, Kazakhstan, Azerbaijan, Bangladesh, China, and Oman.

In its 2020 financial year Iran exported a total of US$7.0bn-worth of building materials and produced 85Mt of cement against a domestic consumption of 65Mt.

Armenia: The government has included cement production under a list of permitted economic activities able to resume from 16 April 2020. Azbarez News has reported that the present lockdown is scheduled to continue until 15 May 2020. Cement and clinker imports from neighbouring Iran, historically the main source of construction cement for Armenia, have continued throughout the coronavirus crisis.

Armenia: The Armenian government has announced that it plans to extend the duration of state duties on cement imported from Iran and several other countries until 1 July 2020. The decision was made on the basis of analysis that confirmed an extension of the customs duties was appropriate. The government said that it would continue to monitor the situation.

According to the RA Statistical Committee Armenia produced 0.59Mt of cement in 2019, 8.1% more than in 2018. The RA Customs Service reported that the country imported 0.31Mt in 2019, a year-on-year increase of 70.5%.

Eurasian Economic Union: The Eurasian Economic Union (EEU) produced 12Mt of cement in the first quarter of 2019. Armenia produced 68,000t and imported 47,200t. Belarus produced 0.84Mt, imported 79,500t and exported 0.26Mt. Kyrgyzstan produced 0.35Mt, imported 38,600t and exported 0.15Mt. Kazakhstan produced 1.47Mt, imported 0.11Mt and exported 0.33Mt. Russia produced 9.3Mt, imported 0.18Mt and exported 0.17Mt. Usually production in the first quarter represents 16 – 19% of annual production. Consumption of cement in the EEU region is expected to grow by 2.5% year-on-year in 2019.

Armenia/Iran: The Armenian parliament has approved a tariff of US$29/t on imported cement from Iran. A previous attempt to pass the bill was blocked in April 2019, according to the Armenpress News Agency. During the recent vote construction workers demonstrated outside the parliament building warning that prices could price as a result of the new duty.
