Research on curing agents made from solid waste for treating soils with varying water contents
In the field of civil and construction engineering,the prevalent situation is the necessity for solidification treatment of a large volume of soil.Presently,the treatment characteristics of curing agents developed from industrial solid waste for soils with varying initial moisture contents remain unclear.This cognitive gap has restricted the promotion and application of the technology in engineering practice.In light of this,the current study employs an indoor testing method to investigate the solidification characteristics and their variation patterns of curing agents based on solid waste in soils with different initial water contents.The research findings indicate that,under the same dosage condition,solid waste-based curing agents exhibit superior performance in terms of setting time adjustability,fluidity,and compressive strength of solidified soil compared to slag Portland cement.The setting time of solid waste-based curing agents is significantly influenced by the water-cement ratio,with an increase leading to extended setting times,which are generally longer than those of slag Portland cement.Furthermore,an increase in the initial water content of the soil prolongs the setting time,while an increase in the dosage of the solidifying agent helps to shorten it.In terms of net paste fluidity,the solid waste-based curing agents demonstrate enhanced fluidity with increasing water-cement ratio,outperforming slag Portland cement.In the aspect of compressive strength of solidified soil,the solid waste-based curing agents also show a significant advantage.
