Turning mining residue into raw material for bricks and tiles – part II: rock flour and crusher dust from natural stone processing

On February 29, 2012, the German federal cabinet enacted the country‘s new resource efficiency program (ProgRess). Due to its enormous consumption of resources, the construction sector is a relevant point of main interest. The federal government intends to increase the exploitation of resource conservation potentials in the production of building materials. In addition to the recycling of actual bricks and tiles, the use of secondary raw materials and mining residue is becoming increasingly important. This paper deals with the question of the extent to which such nonplastic additives, rock...
