Investigation of concrete produced using recycled aluminium dross for hot weather concreting conditions [PDF]

, 2016
Aluminium dross is a by-product obtained from the aluminium smelting process. Currently, this dross is processed in rotary kilns to recover the residual aluminium, and the resultant salt cake is sent to landfills.
