ment process is found more effective steam treatment process on enhancement of volume stability of steel slag L Zeghichi, 2006  experimented on substitution of sand by GBF crystallized slag Tests carried out on cubes of concrete showed the effect of the substituting part of sand by granulated slag (30%, 50%) and the total substi-
Mar 01, 2011· SS Krishnan, N Balasubramanian, in Treatise on Process Metallurgy: Industrial Processes, 2014 331713 Slag Consumption Slag is a by-product generated during the manufacturing of pig iron and steel The slag is crushed, pulverized, and screened for use in various applications, particularly in cement production because of its pozzolanic characteristics
The scale is mixed with a fuel and an agglomeration agent is used to create the mixture The sinter bed is then heated to bring the process to its conclusion Slag Formers For foaming slag to be truly effective, the foam must be created up to a certain height on top of the molten steel material
Blast furnace slag and other lower quality slag streams from iron and steel and non-ferrous metal manufacturing, containing 40 to 45% CaO, can be used as a raw material for clinker making, after being ground together with the other raw materials Slag use of up to 250 kg/t-clinker is reported from Japanese plants (APP, 2010, p 119)
