钢渣蒸汽加压稳定化预处理技术的研究
|
摘要
钢渣的安定性不良,成为其资源化开发利用的难点,若不进行有效处理,钢渣难以像矿渣、粉煤灰一样大容量价值利用。而经过蒸汽加压设备处理后的钢渣,游离氧化钙含量明显降低,通过压蒸釜对钢渣混凝土砌块进行安定性检验,证明经过稳定化处理后的钢渣安定性得到了提高。
The difficulty in the exploitation and utilization of the steel slag resource is caused by its poor stability.A large quantity of recycling for steel slag cannot be carried out similar to mine refuse and fly ash.There is an evident reduction of free calcium oxide in the steel slag processed by autoclave equipment. The stability test of steel slag concrete blocks was conducted by autoclave. It was proved that the stability of steel slag processed by stabilizing treatment has been improved.
