Geopolymers have long been used to stabilise unique soils, and the stabilising conditions freeze-thaw cycles (FTs) a substantial impact on engineering qualities of stabilised soils. The mechanical characteristics microstructure lime (Ca(OH)2) fly ash (FA) saline soils were investigated in this study using Unconfined Compressive Strength (UCS), Splitting Strength, Residual (IR) tests conjunction with X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetry (TG). results indicated that properties optimal at 3% Ca(OH)2 constant 13% FA content UCS splitting strength 8.78 MPa 1.43 MPa, respectively. showed trend rapid decrease then stabilisation increasing FTs, frost resistance was Ca(OH)2. At FTs = 20, IR 40.94% 32.51%, respectively, which higher than those other proportions This attributed fact calcium assisted primarily formation dense network structure hydrated silicate aluminate gels, as well generation ettringite sulphate.
