India: Transport Minister Nitin Gadkari has promoted the use of ‘waste’ materials such as slag cement for the construction of roads. He said that the ministry has decided to build concrete highways in the place of traditional bitumen roads, in comments to local press at a ‘Make In India’ campaign event. He added that slag cement costs up to four times as less as normal cement making it a ‘game changer’. At present a few test roads made with slag cement have been built in the north of the country.

Sweden: Ovako has signed a contract with NCC to supply steel slag to be used as ballast in asphalt. As part of the contract, NCC will buy 50,000t/yr for the first three years and then 85,000t/yr. The road surface should be quieter, more durable and more sustainable, according to NCC-run tests in Borlänge.
