摘要：
In this study, the effects of slag on the properties of lightweight cement-treated soils (LCS) immersed in sodium sulfate solutions were studied. The mechanical properties of the samples after immersions were evaluated by unconfined compressive strength. Microstructural properties were investigated by using X-ray diffraction (XRD) and scanning electronic microscopy (SEM). The results show the LCS can resist sodium sulfate corrosion, and the content of slag affects the internal pore structure of the material, thus affecting the strength and thermal conductivity after corrosion. When the slag content is 10% by weight of cement, the mechanical and thermal property of the LCS after corrosion was the best. (C) 2019 Elsevier Ltd. All rights reserved.
