Global Slag News

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."

Australia: Australian Steel Mill Services (ASMS) and the University of Wollongong have launched an investigation into the possible industrial uses of steel furnace slag (SFS) at the Steel Research Hub in Wollongong, New South Wales. ASMS says that SFS has historically had a lower recyclability than ground granulated blast furnace slag (GGBFS) because of its behaviour when hydrated, which potentially includes expanding. The research team believes that SFS might be a possible ingredient for construction materials, including paving slabs. Tests will involve mixtures of SFS with cement, lime, lignosulphonate, coal wash and plastics.

India: The Border Roads Organisation (BRO) plans to launch a pilot scheme in Arunachal Pradesh to build roads using steel slag. It will work with the Central Road Research Institute (CRRI), according to the Press Trust of India. The intention is to explore building long-lasting roads using an alternative materials to conventional aggregates. The topography of the state - with high annual rainfall, forest vegetation and soil diversity – has also prompted the project partners to try using new materials and techniques.

US: Royal White Cement has leased a site on the Houston Ship Channel in Houston, Texas. Local press has reported that the company plans to build its second cement terminal in the city there. The Houston Peninsula Terminal will operate unloading systems for the storage of cement across three facilities at the site. It is also equipped with multiple railway tracks and heavy truck loading facilities. Royal White Cement owner Marcel Fadi said that the move would help the producer to expand its footprint in Houston and beyond.

Fadi said "We have long operated in the Houston market, but this direct access to storage and bulk unloading along the channel will provide greater efficiencies and flexibility, allowing Royal White Cement to handle and store approximately 100,000t of multiple cementitious products such as slag, grey cement, and white cement."

Ireland: Ecocem has launched Superfine, a ground granulated blast furnace slag (GGBS) for use in specialist applications in the European market. The product is a GGBS that has been ground to a very fine particle size. It is intended to be added to other products to improve their strengths in applications such as high performance and ultra-high-performance concrete (UHPC). It can also be used to improve the finish of concrete and reduce the amount of pigment required.

Superfine will be launched across Europe, with the product already being trialled in Abu Dhabi and specified in projects across Ireland. It is designed to be used as a specialist additive in binders, industrial mortars, ultra-high performance concrete (UHPC) and precast concrete.

Susan McGarry, the managing director of Ecocem Ireland, said “After extensive time in research and development, launching Superfine onto the Irish market is testament to our global range of innovative and sustainable concrete solutions.”
