Argentina: Holcim Argentina has paid US$28.5m to acquire Tensolite, a producer and supplier of precast and prestressed concrete products such as concrete blocks, fences, tiles and paving stones. This move aims to diversify its domestic product portfolio in response to the ‘significant’ decline in local cement dispatches.

The acquisition is valued at US$28.5m, according to The National Securities Commission has reported that Holcim will pay US$19m upon closure of the transaction and another US$6.65m 12 months thereafter. The remaining US$2.85m will be due in five equal annual instalments.

Christian Dedeu, CEO of Holcim Argentina, said “In March, we recorded a 40% year-on-year drop in dispatches, according to the Portland Cement Manufacturers Association. The decision to expand our product range is key to mitigating the sharp drop in sales.”

The deal includes integrating two precast and prestressed concrete plants located in Los Pocitos (Tucuman) and Río Segundo (Córdoba), and adding over 150 employees to Holcim Argentina's workforce. The acquired plants have a total production capacity of 12m concrete blocks per year and 14Mm/yr of concrete beams. Holcim aims for 30% of its revenue to come from non-cement construction services by 2025.

Spain: Bio-Ecomatter, a company based in Extremadura, has launched a new sustainable mortar product without cement or sand, using agro-industrial waste as raw material. This product was developed by founders Carmen Tristancho and Lorena Rodríguez, along with Juanjo Tejado and Marisa Carmona from the Institute of Ornamental Rocks and Building Materials.

Bio-Ecomatter's product composition remains confidential. Beyond reducing reliance on traditional materials like cement, it promotes environmental sustainability by utilising agro-industrial waste. Carmen Tristancho, who heads the innovation department at an environmental engineering firm in Badajoz and co-created the product, revealed that the mortar includes hydraulic lime and agro-industrial waste. The mortar reportedly has a 40% higher performance than standard mortar and is half the density. It has the same texture and workability as conventional mortar, with a formula that minimises carbon emissions and lessens reliance on non-renewable raw materials.

The project, while not aiming to replace traditional mortar, introduces alternative sustainable construction methods. Bio-Ecomatter's product won the sustainable construction award from Metabuilding, an EU-funded project supporting SMEs in the construction sector. Tristancho reveals they are also working on projects using recycled plastic moulds filled with their Bio-Ecomatter mortar.

Tristancho said "We are women in a field very centred on cement and sand, so introducing a new material in construction can be met with scepticism."

UK: Recycling company Scott Bros plans to install a plant to produce low carbon concrete made from filter cake at its soil wash plant in Middlesbrough. The company has been working with Teesside University on a series of trials to find by how much it can reduce the amount of ordinary Portland cement (OPC) it is using in its concrete mixes. It has been researching how to use filter cake, a fine-grained clay, which it produces as a by-product from its two ‘urban quarries’ which convert construction and excavation waste into sand and aggregate. The silicate clay-rich filter cake, which has cementitious properties, is currently used as low value BS-certified pond lining material or inert engineering fill.

The €715,000 research project is being funded by Innovate UK, part of UK Research and Innovation (UKRI), the UK’s innovation agency.

Mexico: Holcim México has acquired the San Juan del Río and Balvanera ready-mix concrete plants in Queretaro from Grupo Comosa. The purchases raise the company’s ready-mix concrete production capacity by 120m³/hr and bring its total number of ready-mix concrete plants in Mexico to 72. As a result, Holcim México's production capacity in Queretaro will double to 432,000m³/yr. Grupo Comosa was the first ready-mix concrete producer in Mexico to obtain environmental product certification for its products, which Holcim México says aligns with its own focus on sustainability.

Director of concrete and aggregates Manuel Sirtori said "This expansion not only strengthens our production network, but also underlines our on-going commitment to sustainable construction and innovation."
