UK: DB Group and Wolfenden Concrete have announced the upcoming launch of Supa Green, a range of cement-free agricultural concrete products produced using DB Group’s Cemfree technology. The partnership says that this assures a 62% maximum CO₂ reduction compared to concrete products made with Ordinary Portland Cement (OPC). It further says that the products have increased acid resistance. Cemfree is a low carbon concrete made using ground blast furnace slag (GGBS) and pulverised fly ash.

DB Group chief executive officer Wayne Zakers said, “DB Group’s mission is to improve the durability and sustainability of construction, working most intimately with our innovative partners. Working with Wolfenden will enable us to embed that innovation within the agricultural sector and to extend the benefits of our Cemfree technology to dairy farmers across the UK. The testing of Supa Green products has proven extremely successful, and so we look forward to the launch of the range, and to helping Wolfenden’s customers meet and exceed environmental targets.”

UK: DB Group has supplied its Cemfree concrete product to a site in Birmingham, West Midlands for use by the Environment Agency in a flood defence project. It says that the agency will use the concrete “for kerb bedding and backing over several kilometres in conjunction with various recycled products in an effort to reduce the projects’ carbon footprint.” Cemfree is a low carbon concrete made using ground blast furnace slag (GGBS) and pulverised fly ash.

Russia: Eurocement subsidiary Belgorodsky Cement has announced the start of commercial production of a new CEM-III slag Portland cement. The company says that the cement is highly water and frost resistant and suitable for use in the construction of massive ground and underground structures. Belgorodsky Cement director general Eduard Androsov said, “We offer our customers an individual approach to solving construction problems and guarantee a stable supply of high quality products in the required volumes and within strictly defined deadlines.”

Russia: Iskitimcement has announced the beginning of CEM-II ground granulated blast furnace slag (GGBFS) cement at its Iskitimcement plant in Novosibirsk Oblast. Regional Weekly News has reported that the cement will be used in road base concrete production and soil reinforcement. Iskitimcement says that the cement has high frost, abrasion and impact resistance and strength of over 5.5MPa. It will sell the cement, the seventh type produced at the plant, in 25kg, 50kg and 1t bags.

Spain: Sidenor has launched Termoslag, a software for the control of slag transit during liquid steel dumping. It aims to reduce steel’s slag content by 10%, thereby reducing raw materials and energy consumption in the steel production process and increasing slag output for circular economic uses such as cement production. Sidenor said, “We are committed to eco-innovation and the circular economy.”

Australia: Boral Australia has launched Innovo, an asphalt system product that uses steel slag as a raw material amongst other recyclables. Recycled materials that can be used in the mix include steel slag, recycled plastics, tyres, recycled crushed glass, recycled asphalt pavement and printer toner. The product has been used in various projects in Queensland, New South Wales, Victoria, South Australia and Western Australia.

UK: Hanson supplied its Regen ground granulated blastfurnace slag (GGBS) product for use on part of the Thames Tideway Tunnel super sewer project in Wapping, London. The product was used to overcome difficult ground conditions. Around 5700t tonnes of Regen, supplied from its Purfleet grinding plant in Essex, was used with 3000t of Ketton cement to create a binder to stabilise soil so work to construct a combined sewer overflow could progress and provide a connection to the main east tunnel.

Costain, VINCI Construction Grands Projects and Bachy Soletanche worked with Hanson in laboratory trials to test the performance of the system and suitability of the selected mix design. Deep soil mixing, a technique that enhances the characteristics of weak soils by combining them with a cementitious binder, was chosen as the final stabilisation method.

The Thames Tideway sewer network expansion is due for completion in 2024 and is happening across 24 construction sites in London, spanning from Acton in West London to Beckton in the east of the city.

UK: Ready-mix concrete (RMX) supplier Capital Concrete has dedicated two 60t silos at its London plants to supply Cemfree, a low carbon concrete made using ground blast furnace slag (GGBS) made by DB Group. It is the only RMX supplier in London supplying the product in this way.

“We’ve seen customer interest pick up recently, interest which is clearly linked to the growing importance of environmental considerations in construction build designs. Capital Concrete is now a leading supplier of Cemfree in the London area and we’re able to supply high volumes of this product anywhere in the London market,” said Luke Smith, the managing director of Capital Concrete.

India: JSW Cement has launched its ‘Comp Cem’ product in Goa. It is a blend of clinker, ground granulated blast furnace slag and fly ash, according to the United News Of India. The new product is intended to help the cement producer expand its distribution network in the southern and western parts of the country.

Ireland: Ecocem says that its slag cement products have saved 10Mt of CO₂ emissions compared to regular cement since it started trading in 2002. It produces cement products from ground granulated blastfurnace slag (GGBS). It says its GGBS cement has a carbon footprint of 32kg CO₂/t compared to 850 - 900kg CO₂/t for Ordinary Portland Cement (OPC). The Irish company operates four plants in Europe with a production capacity of 2.4Mt/yr.
