USE OF FLY ASH AND SHALE FROM COAL MINES
UTILISATION DES CENDRES VOLANTES ET DES SCHISTES HOUILLERS
Over many years the use of fly ash has increased from 30 to 70% of the whole of the production in France. The problem of colliery waste-heaps has been partly dealt with by sowing grass or planting vegetation when the exploitation of the waste heaps would have led to pollution of the environment. Some shale with a content up to 75% of sterile materials has been used, some has been utilized in the form of run-of-mine ore in road construction. Patented-processes for the manufacture of shale bricks and expanded aggregates ("surchiste" and "surex") permit the reduction of the number of colliery waste-heaps considerably. /TRRL/
