The Combimix products included in this study are manufactured in two production sites; one located in Backamo and another located in Bålsta, both locations in Sweden. The products are manufactured through a dry-mix process in a plough-shear mixer. Raw materials are fed automatically from silos, additives are premixed and added automatically as a compound or added without premixing through automatic or manual addition based on the type of additive. The ready-mixed product is filled in small bags, big bags or supplied in bulk depending on the intended use or application.
