试验选用NaOH、CaO、石膏、CaCl2、水玻璃及这些试剂组成的复合试剂作为免烧钢渣陶粒的外加激发剂，通过测定免烧钢渣陶粒在不同激发剂下3、7和28 d的抗压强度，分析对比了各种激发剂对免烧钢渣陶粒抗压性能的影响，并最终通过XRD确定了钢渣在受到激发后生成的水化产物。试验结果表明：激发剂能破坏钢渣中的玻璃体网状结构，释放封存在体内的硅铝铁等活性成分，其中，复合激发剂NaOH+石膏(质量比为1∶1)对免烧钢渣陶粒的激发效果最好，在此激发剂的激发作用下，生成的水化矿物相为钙铁辉石。

Compressive strength of non-sintered steel slag ceramsite,being added of different reagents of NaOH,CaO, gypsum,CaCl2 ,sodium silicate,curing at 3,7,28 d are detected. Effect of various activators on the compressive property of non-sintered steel slag ceramsite is analyzed and compared. The hydrate products of steel slag generated after activation are finally determined by XRD analysis. The test results show that the activators can destroy the vitreous network structure of the steel slag and release active ingredients sealed inside,such as ferro-silico aluminium,among which,the composite activator made up of NaOH and gypsum(ratio of which is 1∶1) has the best activation effect on non-sintered steel slag ceramsite. Activated by this activator,the hydrated mineral phase generated from steel slag is hedenbergite.
