摘　　要：泡沫水泥在建筑保温领域发展迅速,由于泡沫的引入导致泡沫水泥浆体黏度较大,通常施工后需人工刮平作业。以流变仪作为主要研究手段,在改变水灰比和外加剂掺量条件下研究密度300~500 kg/m^3泡沫水泥的力学性能及外加剂对流变性影响。结果表明,对于自流平泡沫水泥,不同密度有其最佳的水灰比,减水剂最佳掺量为0.12%,促凝剂建议掺量为1%,外加剂对自流平泡沫水泥的性能影响与普通泡沫水泥一致。Foamed cement has been developing rapidly in the field of building insulation,foamed cement viscosity is large because of adding bubble into the slurry,usually needs artificial leveling operations after construction, according rheometer This paper will focus on mechanical properties and impact of admixture on rheological property as the change of water cement ratio and the admixture content under the condition of the 300~500 kg/m^3. Results show that self-leveling foamed cement has best water-cement ratio under different densities,the best dosage of water reducing agent was 0.12%,recommended coagulant dosage is 1%,admixture of self-leveling foamed cement performance was consistent with ordinary foamed cement.
