France: Cemex has supplied over 0.3Mm3 of ready-mixed concrete and more than 0.55Mt of aggregates for the Grand Paris Express project over the past three years. It has used mobile on-site concrete plants and a local network of 21 plants in Île-de-France to support the large-scale railway infrastructure scheme.
"The Grand Paris worksites present a daily challenge to deliver ready-mix concrete on time, supply aggregates to our production sites, and move earthworks from the stations and tunnels out of Paris,” said Benjamin Lecendrier, Major Projects Director at Cemex France.
The Grand Paris Express worksites on metro lines 11, 14 and several sections of line 15 South have involved most of Cemex’s staff in the Île-de-France region, with four full-time operatives working in a dedicated unit. Given the scale of operations, logistical organisation is a challenge, with the twin demands of delivering construction materials and removing 40Mt of earthwork by 2030.
Simon Marriott appointed as managing director of Concrete Products by Aggregate Industries
05 June 2019UK: 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.

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.
Italy: Buzzi Unicem says its ready-mix concrete subsidiary Unical has completed the largest continuous concrete casting in Europe at the Galeazzi Orthopedic Institut project in Milan. It pumped 33,000m3 of concrete continuously for 94 hours including 3300 concrete mixer journeys with 106 Unical staff on duty. The new 16-storey building will have a height of 90m once completed.
India: Ramco Cements has launched a new premium blended cement, Ramco Supercrete. The company says that Ramco Supercrete is packed in Biaxially Oriented Polypropylene bags (BOPP) bags to ensure no spillage and thus ensure a cleaner environment. Ramco Supercrete will be targeted at the ‘premium’ section of the cement market.
Ramco Cement also reports that it has invested US$500m in various expansions that are underway. The company's new capacity in West Bengal is already on stream. The company's Odisha plant is expected to be commissioned by October 2019, its Vizag plant expansion will be completed by December 2019, its Jayanthipuram expansion by July 2020 and work on its Kurnool plant will be finished by March 2021.
Lafarge Canada to test carbon capture plans with Inventys and Total at Richmond cement plant
29 May 2019Canada: Lafarge Canada plans to develop and demonstrate a full-cycle solution to capture and reuse CO2 from a cement plant. Project CO2MENT will demonstrate and evaluate Inventys' CO2 capture system and a selection of CO2 utilisation technologies at Lafarge's Richmond cement plant in British Colombia over the next four years. This project is being led by Inventys in partnership with Lafarge Canada and Total. It also received financial support from CCP (CO2 Capture Project), the Province of British Colombia and Canada's federal government through the National Research Council of Canada Industrial Research Assistance Program (NRC IRAP).
"At Inventys, we see a real opportunity to build a CO2 marketplace where tonnes of CO2 are traded between emitters and users," said Inventys president and chief executive officer (CEO) Claude Letourneau.
Phase I of Project CO2MENT, the Contaminant Program, will attempt to reduce harmful organic and inorganic substances, such as sulphur dioxide, dust and soot, as well as nitrogen oxides, from cement flue gas. Phase II, the CO2 Capture Program, will separate the CO2 from flue gas using a customised-for-cement version of Inventys' carbon capture technology at pilot scale. Phase III, the CO2 Reuse Program, will prepare post-combustion CO2 for reuse and support the economical assessment and demonstration of CO2 conversion technologies onsite, such as CO2-injected concrete and fly ash.
Funding for the first two phases is complete and development of Phase I is underway. Phase I will begin operation in 2019 followed by Phase II and III in 2020.
Canada: Sean Monkman, Senior Vice President of Technology Development at CarbonCure Technologies, has been named as Canada’s inaugural Mission Innovation Champion at the fourth annual Mission Innovation Summit (MI4) and 10th annual Clean Energy Ministerial (CEM10) summit hosted by Canada in Vancouver, British Colombia in late May 2019.
Mission Innovation, a global initiative involving 22 countries and the European Commission, has identified carbon capture utilisation and storage (CCUS) as one of eight Innovation Challenges that are key to achieving substantial emissions reductions. Mission Innovation Champions were selected from member countries to celebrate individuals with a track record of progressing creative new ideas that drive the pace and scale of the clean energy revolution.
Qatar: Sika is starting operation at a new concrete admixture plant in Doha. The site will include production lines for concrete-admixture manufacturing as well as a main office and a central storage facility. The new plant follows the establishment of the national subsidiary in 2012.
"The optimisation of our supply chain will enable us to play an even greater role in major construction projects in Qatar. Having our own production capacities available locally makes it possible for us to lower transportation costs and enhance proximity to customers," said Ivo Schädler, EMEA Regional Manager for Sika.
Italy: Martin Engineering has launched its successful ‘Mr Blade’ conveyor belt optimisation program in Italy's construction materials sector. The service is a direct-to-site service to maintain and replace belt-cleaner blades that has previously been implemented in the US and the UK. Martin Engineering offers a range of conveyor belt solutions in Italy for industries like energy and steel. The ‘Mr Blade’ program extends this offering to smaller sites – such as quarries, concrete and asphalt plants. Martin Engineering expects to launch its ‘Mr Blade’ service in other European countries later in 2019.
China: Researchers from the Xinjiang Communications Construction Group have developed a new type of cement-based concrete that uses soil as well as wind-blown sand. The new concrete also uses construction waste and steel slag, according to the Xinhua News Agency. It is intended to lower construction costs and times with applications in infrastructure projects.
France: Fives Group has tested using its FCB Rhodax cone crusher to process concrete wastes resulting from the demolition and deconstruction industry. During an internal innovation competition, the crusher was used to sort hydrated cement paste from the aggregates and sand. The development will enable cement producers to reuse the paste as a cement additive. Ready mixed concrete producers will be able to make new concrete using the recycled aggregates and sand allowing for a reduction in CO2 emissions. Fives hopes to turn demolition concrete waste into a valuable commodity.
