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.

Italy/UK: Ametek Land in the UK has collaborated with Italy’s Danieli on its automatic tapping system to increase operation safety and improve process control for steel plants. The Danieli Automatic Electric Arc Furnace (EAF) Tapping System product allows complete furnace tapping remotely from the main pulpit of a steel plant. The system starts furnace tilting in automatic mode, controlling the furnace position during the complete tapping process.

Embedded within the system are two thermal imaging systems from Ametek Land: its Slag Detection System (SDS-E), branded as Danieli’s Q-Slag, and a near-infrared (NIR) fixed thermal imager that is part of the Ladle Level Detection (LLD) system. The thermal imaging systems are used in conjunction with Danieli software to control steel flow in real time.

Q-Slag makes use of an SDS-E imager to detect the transition between steel and slag. It also quantifies the amount of slag that may pass into the ladle. That information is useful for fine-tuning alloys and lime additions for the secondary metallurgy. In parallel with Q-Slag, the LLD system controls when steel inside the teeming ladle has reached pre-set level positions. Back tilting can be done either in automatic mode (when the pre-conditions regarding steel level and weight are met) or by remote intervention of the EAF operator from the main pulpit.

Ametek Land says that its Slag Detection System can improve operator response times and steel consistency at the end of each tap. Those improvements typically result in up to a 25% reduction in slag depths, compared with traditional methods of stream monitoring.

Danieli designs plants and manufactures and installs machines for the metals industry covering the entire production cycle from raw ore to finished steel products. Ametek Land manufactures monitors and analysers for industrial infrared non-contact temperature measurement, combustion efficiency and environmental pollutant emissions.

UK: David Ball Group has run a series of trials with Bouygues UK of its Cemfree concrete product at a redevelopment scheme at the Gascoigne Housing Estate in Barking, London. The group says that the trial went ‘exceptionally’ well and teaming Cemfree with Bouygues UK further down the line on future projects looks ‘hopeful.’ Cemfree is a low carbon concrete made using ground blast furnace slag (GGBS).

“We are always looking for new ways to innovate, and the carbon-saving potential of Cemfree is considerable. Initial trials have been very positive and we will continue to explore its potential as a sustainable alternative to traditional concrete – a hugely exciting possibility,” said Jean-Marie Perret, a project manager for Bouygues UK, who is leading the Cemfree trials for the Gascoigne Estate.

Indonesia: Semen Indonesia has launched a new slag cement product under the brand ‘Maxstrength Cement.’ The cement producer said it was the first Portland Slag cement produced in the country. The company can producer 1500t/day of the slag cement and it is intended for use in large scale infrastructure projects that require high flexural strength, such as bridges or road flyovers.

India: Ambuja Cement has launched Ambuja Compocem, a composite cement made from fly ash and slag. The product is being produced at its Chhattisgarh plant and it has been introduced to markets in Bihar and Jharkland. It is being marketed to all market segments including individual house builders, real estate developers and infrastructure projects.

“With the launch of Ambuja Compocem, we have achieved a three pronged sustainability approach by conserving natural resources, creating a greener product and fulfilling customer needs for a superior performance product. We call this approach delivering true value,” said Ambuja Cement’s managing director and chief executive officer Ajay Kapur.

Japan: Aichi Steel is set to increase production of AS Shot, a high strength abrasive shot made using steel slag. It plans to upgrade its Chita plant to increase output fivefold for the 2017 financial year, according to Japan Metal Daily. Shooting is applied for plating base materials and removing rust in a wide range of fields including bridges, automobiles and shipbuilding. Use of AS Shot reduces the amount of dust generated during blasting and enables treatment to have a long life and excellent machinability.

India: Tata Steel has launched a new ground granulated blast furnace slag product in Bhubaneswar, Odisha. Around 40 potential customers from the construction, ready-mix concrete and engineering sectors attended the launch event. Speakers at the event included Rashid Merchant from RMC India Readymix and PN OJha from the National Council for Cement and Building Materials (NCCBM). Other senior officials from Tata Steel were also in attendance.
