Abstract

In this article are present the results of physical and chemical characterisation activities, of industrial wastes: ash and slag, drilling sludge, metallurgical slag. Also, were established the conditions in which these industrial waste types could be used as raw materials for manufacture some building materials. The ash can be assimilated with a lightweight aggregate similar to the natural sands, the oil-well drilling sludge presents an advanced similarity with the suspensions of fine particles of sand clays, the steel melting slag in electric furnace has the characteristics of a dense granular aggregate and the secondary treatment steel slag is characterized by the high content of calcium oxide.
