摘要
为实现工业废渣和软土共同资源化利用,文中利用水泥、矿渣和磷石膏固化软土,分别对其力学性能进行室内试验和微观分析。正交试验结果优化得出的最佳配比为水泥∶矿渣∶磷石膏=1∶2∶0.5,固化软土7 d无侧限抗压强度高达4494.75 kPa。
In order to realize common resource utilization of industrial waste slag and soft soil,this paper uses cement,slag and phosphogypsum to solidify soft soil,and carries out laboratory test and microscopic analysis on its mechanical properties respectively.The optimal ratio of cement∶slag∶phosphogypsum=1∶2∶0.5 was obtained by orthogonal test,and the unconfined compressive strength of the cured soft soil reached 4494.75 kPa for 7 days.
