Hoffmann Green Cement Technologies secures first retail supply contract for H-Iona slag cement

29 September 2021

France: Hoffmann Green Cement Technologies has signed a contact with Réunion-based retailer Ravate Group, under which the latter will stock its H-Iona slag cement in its shops in Réunion, Mauritius and Mayotte until 2025. The producer says that the first deliveries will follow in late 2021.

Owners Julien Blanchard and David Hoffmann said “Providing professionals and the general public with the possibility of buying very low-carbon cement, and thus of helping fight global warming, is a source of great pride for Hoffmann. We are delighted to have signed this first H-Iona distribution contract with Ravate Group, an independent family-run business with which we share many values such as innovation and respecting the environment. This partnership will allow us to increase our current order book and generate deliveries of bags of cement from 2021. We intend to sign more partnership deals of this type in order to be able to supply H-IONA and its exceptional benefits, notably environmental benefits, to as many people as possible.” Ravate Group operates over 40 outlets.

Liberty Galați exports 50,000t of granulated blast furnace slag to French clinkerless cement producer

14 July 2021

Romania: Liberty Galați said in June 2021 that it exported 50,000t of granulated blast furnace slag (GBFS) to France. The steel company said that a French cement producer will use the GBFS along with clay and gypsum in clinker-free cement production. The alternative cement reduces CO2 emissions by 80% compared to ordinary Portland cement (OPC), according to the supplier. Liberty Galați’s operations generate 500,000t/yr of GBFS. It says that it has cement industry customers across Europe and Africa.

General Director Aida Nechifor said “Our ambition to become carbon neutral by 2030 involves a new metallurgical route – using direct iron reduction and smelting in electric arc furnaces – increased scrap metal recycling and a transition to domestically-generated green energy. However, we are very happy to be able to ensure that even the by-products of our current production process, such as GBFS, can be used better to help reduce the carbon footprint of other products.”

The state government opposes the decision and has proposed a merger with the National Mineral Development Corporation (NMDC) instead. This would integrate Visakhapatnam Steel Plant within the management chain of other resources used in cement production.

Welding Alloys repairs vertical roller mill at Hanson’s Purfleet slag plant

28 September 2020

UK: Welding Alloys says that it has carried out maintenance on a vertical roller mill at HeidelbergCement subsidiary Hanson’s 1.0Mt/yr Purfleet slag plant in Essex, repairing the mill’s Loesche 46 2+2S grinding table and rollers. The company said that the mill, which had ground 3500t of granulated blast furnace slag (GBFS), was “in urgent need of refurbishment.” Following a wear audit, Welding Alloys took the grinding components back to the profile template using its Integra Wire Mill products.

The group said that “both companies overcame the challenges of completing the project within the limited shutdown period while complying with the Covid-19 lockdown measures.”

Holcim US announces new blended cements branding

28 September 2020

US: LafargeHolcim subsidiary Holcim US has rebranded its blended cement and supplementary cementitious materials range as Envirocore. Envirocore products include OneCem Portland limestone cement, MaxCem blended cement and NewCem slag cement.

The company noted that the partial substitution of cement with supplementary cementitious materials “not only results in more durable, high-performance concrete, but also lowers energy consumption and greenhouse gas emissions. CO2 emissions are reduced by approximately 800,000kg/t of clinker replaced.” It also called on consumers to “adopt solutions that lower carbon emissions.”

Ready Mix Beton to supply slag cement concrete to monorail projects in Egypt

17 September 2020

Egypt: Suez Cement subsidiary Ready Mix Beton says that it has secured a contract for the supply of concrete for the construction of two new monorail lines projects. Due to begin in late-2020, the contract covers the construction of a monorail line between Cairo and the New Administrative Capital and another between 6 October City and Giza. The company says that it will use Suez Cement’s CEM III/A ground granulated blast furnace slag (GGBFS) cement to produce concrete for the 96km monorail network.

Suez Cement said, “CEM III/A cement is highly recommended when building thick concrete supports and massive structures because its hydration temperature of less than 210kJ/kg reduces cracking compared with Ordinary Portland Cement (OPC) when the applied concrete is subjected to dual exposure to sulphates and chloride ions, as happens in coastal areas.”
