India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.

Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."

France: Sustainable concrete producer Materrup has shared plans for its upcoming Bordeaux precast concrete elements plant. The L’Usine Nouvelle newspaper has reported that the facility will produce precast elements from Materrup’s cement-free concrete, which it produces from uncalcined clay, an activator and a precursor at room temperature. The technology, called Clay Cement 1 (MCC1), reduces CO₂ emissions by 50 – 80% compared to ordinary Portland cement (OPC), according to the producer. It previously opened a Euro7m 50,000t/yr plant in the Atlantisub Business Area in Saint-Geours-de-Maremne, Nouvelle-Aquitaine.

India: The India Cements has launched Concrete Super King, a general application cement, and Halo Super King, a cement exclusively developed for use in the production of precast hollow dense concrete blocks.

Vice chair and managing director Narayanaswami Srinivasan said that many of the company’s customers already rely on its products in their precast hollow dense concrete block production. With the launch of Halo Super King, it hopes to further increase the ease of application.

Colombia: Cementos Argos has announced the launch of its new modular concrete solutions subsidiary Soluciones Modulares Argos. The company will produce precast concrete elements for use in housing and infrastructure construction. It aims to build 500 new homes in the second half 2022 and says that its products will halve building times.

Cementos Argos Colombia regional vice president Carlos Horacio Yustysaid "Modular concrete solutions revolutionise the execution of traditional structures and constitute a disruptive bet in construction systems technology."

France: Private equity firm EIM Capital has acquired precast concrete products company Bonna Sabla from Consolis. The producer says that the new ownership will help it to capitalise on its commercial, economic and social situation through an ecological, energy and technological transition.

Chief executive officer Eric Lobbé said “We have the right teams and set of manufacturing facilities in France to pursue and develop our drainage precast solutions through well-known brands as Bonna Sabla, MPB and ABM. To be a pure player will allow us to capture significant organic growth opportunities, as well as being ready for future acquisitions. We will keep on pushing innovation to serve our customers.”

Spain: Cementos Molins has acquired a 100% stake in precast concrete supplier Pretersa Prenavisa for an undisclosed sum. Molins, through its subsidiary Precon, made the purchase from the European investment group Kartesia. It says the transaction will boost its presence and product mix in the precast concrete market in Spain, Portugal, and France.

Pretersa Prenavisa supplies the engineering, design, manufacture, and assembly of precast concrete structures. Its headquarters is based at Teruel and it operates three production plants at Teruel, Jaen and Segovia. It has around 770 employees and reported a turnover of Euro56m in 2020.

Cementos Molins operates in the precast business in Spain through its subsidiary Precon. It operates ten production plants located throughout Spain. The acquisition of Pretersa Prenavisa is Molins’ fifth in 2021. It follows the takeover of Escofet, a concrete design specialist, the acquisition of a white cement plant in Spain from Çimsa group, the acquisition of Calucem, a calcium aluminate cement producer, and the acquisition of the aggregates and ready-mix concrete businesses of HeildelbergCement in Catalonia.

Azerbaijan: Cement companies produced 3.19Mt of cement in the first 11 months of 2021, up by 3.4% year-on-year from 3.09Mt. On 1 December 2021, total cement reserves in stockpiles were 113,000t. Ready-mix concrete production rose in the first 11 months of 2021 by 2.9% to 986,000m3 from 937,000m³, while precast concrete production more than doubled to 301,000m3 from 143,000m³.

Pakistan: BHS-Sonthofen (Tianjan) has reported the successful delivery of two of a total of six twin-shaft batch mixers to the site of CEC-PowerChina and Pakistan Frontier Works’ upcoming Diamer-Basha dam. The Chinese division of the Germany-based company is supplying four DKX 7.00 7m³/batch precast concrete mixers and two DKX 6.00 6m³/batch precast concrete mixers as part of the project. The mixers will contribute towards the 18.6Mm³ of mainly roller-compacted concrete required for the dam’s construction.

General manager Ronny Laux said “The hydraulically bound base layers required for the dam (also known as roller-compacted concrete) must withstand the heaviest of loads. Our mixers are designed to handle demanding mixing tasks. The twin-shaft batch mixers meet the highest demands for mix homogeneity and reproducibility, even with large quantities – ensuring optimum concrete quality.”

Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO₂. EuropaPress has reported that the use of CO₂ would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO₂ from the concrete’s production.

Germany: Scientists at the University of Kassel in Hessen have launched a study into the use of ash from waste incinerators in precast concrete production. The Hessische Allgemeine newspaper has reported that a waste-to-energy plant in Kassel will provide the ash for concrete production in partnership with local companies Kimm Baustoffe and Gebäudeke Baustoff-Recycling. The study aims to produce pre-cast concrete elements containing at least 30% ash, beginning with paving slabs and noise barriers.

Project leader David Laner said that ash has the potential to help lower concrete’s carbon footprint. He said “So far, it has been put to lesser-value uses; we make a product out of it - upcycling instead of downcycling.”
