UK: Cemex will supply 40,000t of lining-sprayed concrete for the construction of the 13km central section of the Thames Tideway sewer project in Greater London. Engineering partners Ferrovial Construction and Laing O’Rourke will use the concrete for shafts and launch tunnels. The company produced the concrete at its Buxton, Derbyshire concrete plant. It says that it offers ultra-high strength, consistency and two-hour workability in line with the stringent requirements of the job. It also needs to be pumpable with a pipeline length of up to 400m. The producer will deliver up to 3000t/month of the concrete to Central London over ‘a few months.’

Europe, Middle East, Africa and Asia president Sergio Menendez said “The Thames Tideway Tunnel project is one of incredible scale which will solve serious capacity issues with London’s sewer system and have considerable benefits for the area’s wildlife and population, while also preventing pollution, creating jobs, a rejuvenated river economy and new areas of public space.” He added “This is a remarkable piece of engineering, and we’re proud to be working with world-class contractors to build this key infrastructure in the most sustainable and cost-effective way possible for one of the world’s greatest cities.”

The 25km ‘Super Sewer’ will conduct the city’s sewage to a new treatment facility at Abbey Mills in the Borough of Newham. The central section runs between 30m and 60m below the Thames past part of West London, Westminster and the City of London.

France: Hoffmann Green Cement Technologies has begun construction of its second cement plant, called H2. The company will build the plant next to its existing H1 plant in Bournezeau, Vendée, using its clinker-free cement made from blast furnace slag, clay and gypsum. It will have a capacity of 250,000t/yr and cost Euro22m.

Co-founders Julien Blanchard and David Hoffmann said “This second plant is a key milestone in our development plan in order to increase our production capacity. H2 will enable us to address the growing demand for our clinker-free low-carbon cement, as we have recently signed a number of partnerships with key construction players such as Groupe GCC, KP1, Capremib, Cemex and Eiffage Génie Civil. We would like to congratulate our teams, as this second plant is the result of a multitude of challenges taken up in 2020 in order to increase production capacity. It is the rare combination of an exceptional industrial performance and a minimised environmental impact. This structure demonstrates our industrial excellence and perfectly and genuinely materialises our intent to decarbonise the construction sector.”

Head of new construction Olivier Lefelle said “This second plant represents a major and structuring step. The choice of a vertical model for the mixing tower is an innovative concept in the construction sector and is perfectly in line with Hoffmann Green’s responsible vision. Furthermore, by using Hoffmann cement for its construction, this building site will enable CO₂ emissions to be reduced by around 20,000t.”

Spain: Cemex España has announced plans to invest Euro4m in upgrades to its Buñol, Valencia, Muel, Zaragoza, Raspeig, Alicante and Rubí, Barcelona mortar plants. The upgrades will increase production capacity, safety and efficiency and improve product quality. The company said that the promotion of its range of over 160 special mortars is a main focus of the investment.

Cemex Europe, Middle East, Africa and Asia regional president Sergio Menéndez said “We recognise the growing demand for innovative mortar solutions for new and existing buildings to reduce carbon emissions in our cities and support the EU Renewal Wave. Our wide range of mortars for dry silos, in bags and ready to use, is reinforced by expert solutions for paving streets, plastered walls, tunnel solutions, plasters and special sands.”

The group is also investing in upgrades to production and packaging systems in its mortar segment in Poland and the UK.

Spain: LafargeHolcim subsidiary Holcim España has informed the works council and employees of its Jerez de la Frontera cement plant of possible planned changes to the plant’s production structure. The company intends to convert the cement plant into a grinding-only facility. The reasons for the decision were regional overcapacity, falling export volumes and prices and reduced allocations of EU CO₂ emissions credits. It says that under the plan the new grinding plant would continue to serve the market in the region. The communication constitutes the beginning of a collective dismissal process.

General director Isidoro Miranda said that the company wants “to work with the social partners to reach an agreement that allows the continuity of our activity in the town of Jerez.”
