Abstract
An arrangement and a method for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.
