Nigeria: LafargeHolcim subsidiary Lafarge Africa says that it has signed an agreement with the Cross River State government to build a 38km concrete road connecting its local cement plant to the wider network. Chief executive officer (CEO) Khaled El Dokani said the project was a major contribution of Lafarge to the state at large with the purpose of making the roads safer for the citizens. The road is intended to divert trucks away from a nearby city centre once it is completed.

Uzbekistan: The Ministry of Transport has secured a US$274m loan from the Asian Development Bank for investment in the construction of a 240km road in Karakalpakstan. Asian Development Bank senior transport specialist Pavan Karki said, “As a landlocked country, Uzbekistan has made regional connectivity a central element of its transport policy. This project will help develop the country's potential as a regional transport and logistics hub between Europe and Southeast Asia, contributing to economic growth.” The road will be part of the Central Asia Regional Economic Cooperation Programme Corridor 2. Uzbekistan Newsline has reported that the project will generate ‘significant demand’ for the country’s cement producers.

Germany: HeidelbergCement has reported the successful resurfacing of a section of Federal Motorway 5 (BAB 5) between Karlsruhe and Frankfurt using a concrete made from low-alkali cement produced at its 1.4Mt/yr-capacity Schelklingen, Baden-Württemberg integrated cement plant. The company used over 3600t of cement to produce the 12,000m³ of concrete required for the 3.2km stretch of road. Traffic infrastructure product manager Klaus Felsch said, “The cement’s low alkali content significantly reduces the risk of an alkali-silica reaction and maximizes the durability of the concrete.”

India: Odisha has received its first cement-free road near Amanapada, Cuttack District. The Pioneer newspaper has reported that researchers from the Kalinga Institute of Industrial Technology (KIIT) developed the new material, made from 100% industrial waste, in order to cut the CO₂ emissions involved in cement production and in anticipation of an acute limestone shortage in India in 25 – 50 years. KIIT founder Achyuta Samanta thanked the students whose work brought this pilot project to fruition. “The new technology has the potential to bring about a revolution in engineering construction,” he said.

India: The Federation of Indian Chambers of Commerce and Industry (FICCI) has asked the government to restart home and road building to help cement producers. The Press Trust of India newspaper has reported that all construction work has stalled since 25 March 2020 due to the coronavirus lockdown. The FICCI believes that Indian cement demand is currently set to decline by 10-12% year-on-year. To relieve the sector, the FICCI urged the Indian government to lift the lockdown in metropolitan areas in order to allow the continuation of residential construction, which accounts for 60-65% of cement demand.

To protect domestic producers from any import dumping post-crisis, the FICCI has suggested that Indian cement sales should be subsidised. It also requested a ‘relaxation of environmental emission norms’ until mid-2022 ‘to save the industry from additional capex expenses.’

Colombia: Mexico-based Cemex has announced the resumption of operations at its 2.8Mt/yr Caracolito plant in Ibagué, Tolima Department on 13 April 2020. Noticias Financieras News has reported that Cemex Colombia will resume the supply of its products to ‘infrastructure and public works that cannot be suspended, as well as for emergency care projects and road projects.

Cemex will have to wait for the Colombian government to lift its coronavirus lockdown to restart supplies to customers.

Russia: Russian producers sold 2.4Mt of cement in January 2020, up by 9.6% from 2.2Mt in January 2019. This is in line with Unioncement’s optimistic forecast of 6% year-on-year demand growth. The coming construction season promises sustained growth due to the planned renovation of housing stock, the implementation of integrated development projects and an increased share of roads built using cement concrete, in line with the country’s 2020 Housing and Urban Environment programme and President Putin’s social initiatives.

UK: CemFree cement-free concrete has been applied volumetrically for the first time in a 52m3 repair to the Woodford West Viaduct on the M25 London ordbital motorway in Essex. The reason behind the choice of method was the unavailability of batching plants at night, which was the only time that a team of Jackson, DB Group and Axtell employees working on behalf of Connect Plus were permitted to perform the work on the UK’s busiest road. CemFree said that 9.4t of CO2 emissions were cut by comparison to the same project undertaken with ordinary Portland cement (OPC). Jackson director of highways Paul Watson said, “We hope this marks a turning point on the M25 and the wider Highways sector for using low carbon alternatives.”

Cemfree uses 95% ground granulated blast furnace slag (GGBFS) and a 5% alkali activator, removing the need for cement. This gave CO2 emissions of 114kg/t, which the company says is 77% lower than conventional (OPC).

Russia: Siberian Cement’s production increased by 3.0% year-on-year to 3.2Mt in 2019 from 3.1Mt in 2018. The company estimated that demand over the period in Siberia, Buryatia and the Trans-Baikal region grew by 4.4% year-on-year to 5.3Mt/yr from below 5.1Mt/yr in 2018. Siberian Cement owner Sibtsem Holding Company’s first vice president Gennady Rasskazov suggested mining and metallurgical projects, the bridging of the River Ob and infrastructure development for the World Youth Hockey Championship 2023 as factors contributing to the rise in demand.

Germany: Buzzi-Unicem subsidiary Dyckerhoff has paved the 3700m2 of road outside the limestone quarry at its 0.4Mt/yr integrated Geseke plant in North Rhine-Westphalia. It used a concrete blend containing PKZ Doppel N cement produced at the Geseke plant, which it applied to a thickness of 20cm over an asphalt base. Dyckerhoff made the decision to pave the road ‘to minimise dust emissions, especially in prolonged dry spells.’ It says the concrete’s low water content and good compression give the road a strength rating of 50N/mm2.
