Mexico: Property developer Immobiliaria Ancore will use Cemex Mexico’s Vertua reduced-CO₂ concrete in the construction of the upcoming 100-storey Rise Tower in Monterrey. Cemex will supply a high-altitude concrete pouring system for the project. The concrete supplier said that the development aims to secure LEED, WELL, Green Globes, bEQ and NMX-164 certifications.

Cemex Mexico president Ricardo Naya said “We’re honoured to be working on a project that will establish the new standard for sustainable high-rise construction in Latin America. Cemex brings vast experience in sustainable construction, providing lower-carbon building materials, lower-waste practices and zero use of potable water in our concrete production.”

US: Cemex USA has poured 18,300m³ of Vertua reduced-CO₂ concrete in the construction of the Centennial Tower at Houston Methodist Hospital in Texas. Cemex USA says that it successfully completed the 20hr pour at the world’s largest medical complex without interrupting surrounding emergency services.

President Jaime Muguiro said “Cemex’s purpose of building a better future comes to life when we participate in projects that improve people’s quality of life, particularly in the area of health services, in the communities in which we serve. Not only are we providing expert logistics and resilient materials, but we are also providing an alternative to lower the carbon footprint of the project with our more sustainable solutions.”

World: The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO₂ cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO₂ emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net Zero Roadmap. The applicants are presenting their pitches to GCCA members on 30 June 2023. All those accepted will gain access to members' plants, labs, networks and expertise. The following start-ups made the Innovandi Open Challenge 2023 shortlist:

GCCA cement director and innovation lead Claude Loréa said “We received more than 70 quality applications, so drawing up a shortlist was challenging." Loréa continued "Our essential industry needs something easily scalable and affordable. Those start-ups on the list demonstrated the most potential, and we look forward to hearing more about their ideas. But we’ll also be keeping in touch with other start-ups who didn’t make this year’s shortlist, with future projects in mind.”

Spain: Holcim has introduced its EcoPact Prime concrete and mortar range, following a strong reception in other European markets, including Switzerland, Germany and France. The EcoPact Prime range is presented as a sustainable portfolio of concrete and mortar products offering a 70% reduction in CO₂ compared to equivalents based on ordinary Portland cement (OPC).

Manuel Barrero, director of the concrete activity at LafargeHolcim Spain, said “Decarbonisation is a fundamental pillar of our business strategy. Therefore, in our objective to develop materials and solutions that allow us to build better with less, we are going one step further by introducing this new product to the Spanish market.”

All the products in the EcoPact Prime range have their own Environmental Product Declarations (EPD). They incorporate low-emission cements, also from the EcoPlanet range, selected aggregates, additions, water, special additives and use electrical energy generated from renewable sources in their manufacture.

The products are intended for the construction of all structural elements, including beams, walls, floors, foundations or pillars, as well as self-compacting structures, those that need to drain and those that need to exhibit particular aesthetic qualities.

Spain: Cemex España has supplied concrete from its Vertua Plus range for the construction of an 81-home housing development in Madrid. The estate, called Torrejón Park, will be Spain’s first to be built entirely from Vertua reduced-CO₂ cement. Cemex España says that the products used offer 50 – 70% lower CO2¬ emissions than ordinary concrete. Developer Neinor Homes will additionally recover over 80% of construction waste for recycling.

France: Eqiom’s demolition waste recycling plant Gennevilliers in Paris has processed 10,000t of material since it opened in January 2022. The site has a target of 50,000t/yr in its first year of operation. Sand, gravel and larger aggregate fractions are screened from the concrete in a ratio of 40%, 20% and 40% respectively, according to Le Moniteur. The gravel is used at a nearby concrete plant whilst the sand and aggregate is used mostly in road construction.
