Abstract

To promote the resource utilization of calcium carbide residue in road engineering, the calcium carbide residue as cementitious material was used to stabilize the two kinds of fine-grained soils. The effects of mixing method and compaction delay time on the strength of the stabilized soils are investigated by a series of unconfined compressive tests. The results show that the strength of the two stabilized soils can be increased respectively by about 42% and 23% with the same three-time addition mixing method for the wet calcium carbide residue, compared to the one-time addition mixing method. While for the dry calcium carbide residue, the strength of the stabilized soil cannot be improved with the same three-time addition mixing method. The unconfined compressive strength of calcium carbide residue stabilized soil increases first and then decreases with the time delay of compaction, and the appropriate delay time of compaction for the two stabilized soils is about 16 h and 4 h respectively. The results provide a reference for the engineering application of calcium carbide residue stabilized soil.
