Abstract

The various periods mechanical performance of super sulphated cement(SSC) with different fineness are investigated in this paper. The hydration exothermic rate, hydration products and morphology of SSC are tested with differential scanning calorimetry(DSC), X-ray diffraction analysis(XRD) and scanning electron microscopy(SEM), separately. Experimental results show that sample particles in turn become finer followed by No.SSC-1, SSC-2 and SSC-3, the compressive strength of SSC-3 and SSC-2 are significantly higher than SSC-1 with same ages, which are 11.7MPa and 5.8MPa higher than SSC-1sample at 3days, and, 19.9MPa and 17.5MPa higher than SSC-1sample at 28 days, respectively. With the increasing of specific surface area(SSA), the duration of induction period was shortened nearly more than 10 hours, the amount of ettringite phase and C-S-H gel also significantly increased, which makes SSC paste more compact.
