摘要：
In this research, the setting time, compressive strength, cement mortar fluidity, X-ray diffraction, scanning electron microscopy and hydration-heat release rate were adopted to assess the effect of Portland cement on magnesium oxysulfate (MOS) cement prepared by light-burned dolomite ores. The experimental results showed that adding Portland cement in MOS cement will greatly reduce its mechanical property. But, a small amounts of Portland cement in MOS cement can shorten its setting time and maintain most compressive strength meanwhile.
