QUẢNG NGÃI — The Hòa Phát Dung Quất Steel Joint Stock Company shipped its first batch of S95 ground granulated blast furnace slag to Australia on Thursday, where strict standards and stringent requirements are applied.

Comprising 2,500 tonnes of S95, the batch was produced at the Hòa Phát Dung Quất Iron and Steel Integrated Complex.

The granulated blast furnace slag is a by-product of the iron and steel production process using closed blast furnace technology. Due to the extremely rapid cooling with high pressure water, the granulated blast furnace slag is good for cement and concrete and has been used for a long time around the world as well as in Việt Nam.

S95 fine blast furnace slag products contribute to treating solid waste during Hòa Phát’s green steel-making process, while protecting the environment and creating a stable source of revenue for the group.

The material can be applied as highly-activated mineral additives in the production of cement, concrete and mortar, or as a binder to reinforce weak ground. With S95, it is possible to mass produce concrete by reducing hydrothermal heat, producing heat resistant concrete due to increased thermal stability, with durability in seawater, salt water and brackish water, due to the increased waterproofing of the concrete, preventing the erosion of chlorine and sulphate and meeting the requirement to increase the life of works at sea, on islands and in coastal areas.

With two iron production complexes in Kinh Môn, Hải Dương Province, and Dung Quất in Quảng Ngãi Province, the Hòa Phát Group is able to supply the market with 2.6 million tonnes of S95 each year.

This first export affirms the group’s reputation in the global market, while opening up a new consumption channel for S95.

Australia plans to order larger volumes of S95 in the future. — VNS
