UK: Climate change protestors from the Extinction Rebellion group have been arrested for blockading a ready-mixed concrete plant operated by London Concrete at Bow in London. Concrete from the plant is being used to supply a major road tunnel project at Silvertown beneath the River Thames, according to Reuters. Extinction Rebellion blamed concrete production for being a major source of CO2 emissions and it also has concerns about dust pollution. Seven people were arrested by the Metropolitan Police for aggravated trespass. London Concrete is part of LafargeHolcim Group. It operates 12 concrete plants in London.

UK: Hanson Cement says that the first phase of a Euro27m upgrade project to its integrated Padeswood plant in Wales has been completed. The upgrade has included the installation of a 0.65Mt/yr cement grinding mill as well as enhancements to production capacity and efficiency gains. The plant can now, with the aid of existing ball mills, match cement grinding with its kiln capacity.

“The nearly new Loesche vertical roller mill, housed in a 34m-high building, started its life at a grinding plant in Bilbao. It had only 7000 operational hours on the clock and was in excellent condition. After dismantling it piece by piece, specialist contractors moved it to the UK where it was reassembled on site at Padeswood,” said Jim Claydon, Hanson UK cement managing director.

Other improvements at the site include the installation of three new rail cement silos that have been installed alongside the existing railhead. This will allow up to three trains a week to be loaded for deliveries to Hanson depots in London, Bristol or Glasgow. The new silos will reduce the transportation of cement produced at Padeswood to customers by road. In addition to the increase in grinding capacity, other recent capital investment at Padeswood include the installation of a plastic packing machine, and the re-commissioning of an existing paper packaging machine and an upgrade in the capability to use recycled paper and plastics as fuel.

India/UK: The Global Cement and Concrete Association (GCCA) has launched GCCA India. As part of GCCA’s strategic partnership with the World Business Council on Sustainable Development the new office, based in Mumbai, will take over the work of the Cement Sustainability Initiative (CSI) India, which formerly served as the sector’s sustainability alliance.

GCCA India plans to ensure that, from a sustainability angle, innovation in technology and manufacture, and collaboration across the wider built environment, the Indian cement sector can play a key leadership role. It will develop a work program that will focus on the wider global GCCA priorities but with practical application across the Indian built environment.

Germany/UK: The Global Cement and Concrete Association (GCCA) and the European Cement Research Academy (ECRA) have announced a formal partnership agreement. The strategic alliance is aimed at fostering innovation in the cement and concrete sectors and across their value chain partners.

Under the terms of the agreement, the GCCA and ECRA have granted each other mutual membership in order to aid collaboration. In addition, ECRA’s managing director will join the GCCA’s Partnership Council and the GCCA’s cement director will join ECRA’s Technical Advisory Council. The two parties will share their current work programs and identify key areas for future collaboration and input.

“ECRA’s mission to advance innovation in the cement industry within the context of sustainable development, as well as communicating key knowledge and research findings in technology, fits perfectly with the GCCA’s aim of driving advances in sustainable construction,” said Benjamin Sporton, the chief executive officer (CEO) of the GCCA.

UK: Hanson has been part of a new continuous concrete pour record in the UK as part of its work at the EDF Energy’s Hinkley Point C (HPC) new nuclear power station in Somerset. It supplied raw materials for the concrete to main civil engineering contractor BYLOR, which operates the on-site concrete production plant. The 9000m³, five-day, pour was to construct the last of five reinforced concrete segments that make up the cross-shaped foundations on which all of the first nuclear reactor’s buildings will sit. The record-breaking pour beats the previous UK record set by the Shard skyscraper in London.

The completion of the foundation platform, which is up to 4m thick, represents a significant milestone for the project, described by EDF Energy as J-zero. It marks the transition from below ground activity to the construction of permanent reactor buildings above ground.

Hanson says that mix design for HPC took three years of development and testing to ensure that the concrete was of the required quality mandated by the Office for Nuclear Regulation. The subsidiary of Germany’s HeidelbergCement has 65 employees directly involved in the HPC project team. To date Hanson has supplied 51,000m³ of concrete, 2.5Mt of aggregates, 210,000t of marine sand, 65,000t of cement; 105,000t of ground granulated blast furnace slag (GGBS) and 125,000t of asphalt.

France: Cem'In'Eu plans to raise Euro55m by the end of 2019 to support building new cement grinding plants in Europe. It opened its first 0.25Mt/yr grinding plant at Tonneins, Lot et Garonne in 2018, according to Les Echos newspaper. Construction of a new plant at Portes-lès-Valence, Drôme is scheduled to start in mid-2019. Construction of a larger 0.5Mt/yr plant at Montreuil-Bellay, Maine-et-Loire is anticipated to start in September 2019 for a commissioning date of February 2021. This project will cost Euro35m. Other projects are planned for Chalon-sur-Saône, Saône et Loire and Ottmarsheim.

International projects include a plant at Ottmarsheim, Haut-Rhin in Switzerland and Thamesport in the UK. The former is expected to gather all the necessary permits by September 2019 with construction to follow by the end of the year. An additional project is being planned at the port of Gdynia in Poland.

UK: Aggregate Industries has appointed Simon Marriott as the managing director of its Concrete Products division. He has also been promoted to the executive committee of the company as part of a strategic decision to raise the profile of the division. The new role will give him responsibility for all hard landscaping aspects of the business including Charcon, Bradstone, Masterblock, Charcon Construction Solutions and Simply Paving. He will also lead the marketing communications function.

Marriott started his career as a plant manager before moving to Bardon Aggregates in 1996. When it merged with Camas to become Aggregate Industries, he become general manager of the Express Asphalt division and later became director of the mainstream asphalt division’s southern region. He then ran Bardon Concrete and Aggregate Industries’ cement importing function, before becoming director of Concrete Products in late 2015.

UK: Aggregate Industries has launched its Lafarge Endure SR, a CEM II blended cement product that uses fly ash. It says that the product has a lower embodied CO₂, has improved plastic and hardened properties when used in concrete and has enhanced suitability for all ground types. Lafarge Endure SR is resistant to sulphates, allowing contractors and suppliers to scope a wider variety of projects. It also uses 10% less water than CEM I products to reach a workable consistency and offers improved pumpability and mixing efficiency.

“As its name suggests, Lafarge Endure SR is designed to dramatically increase the longevity of the concrete it forms a part of. It is a great solution for contractors that want to reduce the environmental impact of their build while simultaneously improving its life span,” said Steve Curley, Commercial Director at Aggregate Industries.

UK: Breedon Group has appointed Amit Bhatia as its non-executive chairman with immediate effect. He has served as deputy chairman since April 2018 and he succeeds Peter Tom, who has retired. Bhatia created Hope Construction Materials and served as its executive chairman for over three years until it was acquired by Breedon in mid-2016, at which point he joined the board of Breedon.

Antarctica/UK: Hanson has transported 125t of bagged cement from its Ketton plant in the UK to the British Antarctic Survey’s Rothera Research Station in Antarctica. Construction company BAM Nuttall is upgrading a wharf at the site to improve ship and boating operations and allow it to accommodate the RRS Sir David Attenborough as well as to reduce manual handling cargo loading/unloading time.

The subsidiary of Germany’s HeidelbergCement worked with BAM Nuttall and civil engineering company Keyline to set the technical specification of the cement. Each of the 25kg bags were vacuum sealed and double shrink wrapped onto heat-treated pallets to reduce the risk of contaminating Antarctica’s environment with foreign organisms.
