【正文】 an meet the quality requirements of P?C 32. 5, cement of the lowest strength class. (2) Cr and Ni which are the major heavy metals in stainless steel slag, normally exist in stab le chemical state. The leaching concentration o fall heavy metals of stainless steel EAF slag and its posite cement are far less than the corresponding limits of the identification standard for hazardous wastes. Stainless steel EAF slag can be safely used as admixture to produce posite cement mixed with cement clinker References [1] State Environmental Protection Administration of China.
