Qatar: The Ministry of Municipality and Environment (MME), the British Transport Research Institute (TRL), Qatar Steel and Ashghal have been running a pilot project to use steel slag in the construction sector including to build roads. The test is part of the country’s infrastructure development in the lead up to the 2022 FIFA World Cup, according to the Gulf Times. Qatar Steel has accumulated large quantities of steel slag from its plant in Mesaieed. It produces over 350,000t/yr and has a stockpile of over 1.6Mt.

Slag road construction trials were conducted at a Qatar Steel site in 2016. The TRL has since recommended production of slag aggregate, certification of slag products by the authorities including MME and Ashghal, development of case studies and the inclusion in the next update to the Qatar construction specification.

Delivery is scheduled to take place before the end of 2017. No price for the order has been disclosed.

The order is for a MVR 5000 C-4 mill equipped with a 4300kW-drive and four grinding rollers with active redundancy. The plant will grind granulated blast-furnace slag with a fineness of about 4,500 cm²/g acc. Blaine and it will also be able to grind composite cements from varying portions of granulated blast-furnace slag, fly ash and gypsum.

Core components of the mills, including the roller, tension system, grinding bowl and planetary gearbox, will be supplied from Europe.
