Research on the application of steel slag-based cementitious materials in soil solidification
Steel slag,as a large-scale industrial solid waste,has problems such as large output and insufficient utilization.Therefore,this article designs and studies a steel slag-based cementitious material and applies it to soil stabilization.The experi-ment compares the steel slag-based cementitious material with cement,and explores the unconfined compressive strength,water sta-bility,immersion expansion rate,resistance to dry-wet cycle and freeze-thaw cycle ability of steel slag-based stabilized soil and ce-ment stabilized soil.Considering the cost and performance of the material comprehensively,the optimal dosage of steel slag-based cementitious material is 7％.At this dosage,the unconfined compressive strength of steel slag-based stabilized soil is higher than that of cement soil,and as the particle size of steel slag decreases,the unconfined compressive strength of stabilized soil increases,the water stability and resistance to dry-wet cycle ability of steel slag stabilized soil are better than those of cement soil,the im-mersion expansion rate is similar,which can meet the requirements of general engineering applications;however,the freeze-thaw performance is poor and cannot meet the special use requirements in severe cold areas.
