Heat resistant concrete resurfacing at Outokumpu steel plant
International stainless steel company, Outokumpu, operates a stainless melting and continuous casting facility in Sheffield, UK. When the need came for the company to resurface the site roads, scrap yard and areas surrounding the furnaces, it was clear that the products specified would need to be durable, demonstrate superior strength and be able to withstand extremely high temperatures. Products would also need to possess early drying and early strength gain properties as the project would need to be completed within the steel works' two week maintenance shut down period.
Tarmac Toproc was specified for use at Outokumpu's site (formerly Avesta and previously British Steel Corporation) thanks to its proven results.
As the site roads are frequently subjected to loads of more than 28 tonnes and thousands of tonnes of metal being dropped, lifted and scraped along the surface day in, day out, a product with superior strength was vital. Tarmac's Toproc AA, a general purpose formulation offering a good balance of high performance properties, was specified by Outokumpu for the site roads and scrap yard areas, combined with steel fibres for added strength.
For furnace areas, where temperatures can reach as high as 1500°C, and for the underlay in the cooling beds, Toproc HR demonstrated all of the required properties.
Why Tarmac Toproc?
For Outokumpu, product consistency, impact and abrasion resistance, combined with early drying were essential to the project. Having already seen the demonstrable benefits of Tarmac's Toproc products on the site, the company believed in the consistent results the range was able to offer.
The products used in the latest installation proved once again to be the ideal solution. Attaining superior strength in a matter of hours, not weeks, and drying quickly to dramatically cut installation times, the project was easily completed within the two week timescale initially set by the company.
In addition, by providing heat resistance in extreme temperatures, Toproc HR is particularly suited to applications such as foundry floors and hot metal storage areas such as those seen at Outokumpu's Sheffield site.
Toproc HR benefits
