摘要

摘要: 采用磷石膏、钛矿渣、熟料和硅酸钠配制了10组超硫酸盐水泥，对基体的抗压强度、水化放热、水化产物进行了研究，并对纤维增强后的抗折强度、拉伸强度和抗冲击强度进行测试。结果表明，熟料和钛矿渣均能有效提升超硫酸盐水泥的抗压强度，并能促进水化放热和二次水化反应。较优的水泥配比为磷石膏∶钛矿渣∶熟料∶硅酸钠=25∶60∶13∶2，此时抗压强度达到42.1 MPa。玄武岩纤维可显著提高超硫酸盐水泥的抗折强度和抗冲击强度，表现为：当掺入0.3% 6 mm纤维时，试件的抗折强度提升了27.0%；掺入0.6%的12 mm纤维时，抗冲击强度提高了120.3%。拉伸试验结果表明，玄武岩纤维对提升水泥的极限拉伸强度不利，但能提高水泥的拉伸应变能力。

Abstract: Ten groups of super sulfate cement (SSC) were prepared by phosphogypsum, titanium slag, clinker and sodium silicate. The compressive strength, hydration heat release and hydration products of the matrix were studied, and the flexural strength, tensile strength and impact strength after fiber reinforcement were tested. The results show that both clinker and titanium slag can effectively improve the compressive strength of SSC, and promote hydration exothermic and secondary hydration reaction. The optimal cement ratio is phosphogypsum 25%, titanium slag 60%, clinker 13%, sodium silicate 2%, and the compressive strength reaches 42.1 MPa. Basalt fiber can significantly improve the flexural strength and impact strength of SSC. Specifically, with an addition of 0.3% 6-mm fiber, the flexural strength of the specimen increases by 27.0%. The impact strength increases by 120.3% when 0.6% 12-mm fiber is added. The tensile test results show that basalt fiber is disadvantageous to the improvement of the ultimate tensile strength of cement, but can enhance the tensile strain capacity of cement.
