摘要

The widespread use of lithium batteries has led to a significant increase in the production of lithium slag waste. In response to this challenge, the emergence of lithium slag presents new opportunities for the development of the construction industry. This study prepared lithium slag-based geopolymer (LS-EGC) by using lithium slag as fine aggregate. The compressive strength, flexural strength, and freeze–thaw cycling tests of LS-EGC were conducted to study its mechanical properties and durability. Thermal stability, pore structure, crystalline phase composition, chemical structure, functional groups, and microstructure of LS-EGC were further analyzed using techniques such as Thermogravimetric Analysis (TG-DTG), Mercury Injection Pore Method (MIP), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). By adjusting the dosage of rice husk ash, the strength of LS-EGC can reach 77.6 MPa, with a flexural strength of 7.4 MPa. The incorporation of multi-walled carbon nanotubes (f-MWCNTs) and steel fibers also resulted in LS-EGC with a high proportion of harmless pores, reaching 58.98%, demonstrating a dense microstructure, good interfacial transition zone, significant environmental benefits, and excellent mechanical and freeze–thaw resistance properties. This study is expected to provide a more theoretical basis for the recycling of lithium slag and the development of green LS-EGC.
