外文摘要：The macro properties of cementitious materials are largely dependent on the internal structure at the nano-scale. The distribution of hydration product phases in cement paste containing lithium slag (LS) and the properties of interfacial transition zone (ITZ) in corresponding mortar have been investigated from the nano-scale structure perspective. The results indicate that LS has little effect on the volume fraction of gels including C-S-H gels and aluminosilicate gels in porosity and hydration product phases, and however, increases the volume fraction of HD C-S-H in gels. In addition, LS increases the volume fraction of porosity, but decreases the volume fraction of CH. The elastic modulus of matrix in mortar containing LS is increased, and the thickness of ITZ in the corresponding mortar is decreased.
