摘　　要：主要研究了水灰比、标准养护龄期、掺合料掺量对硫铝酸盐水泥基混凝土抗碳化能力的影响,并与普通硅酸盐水泥基混凝土抗碳化能力进行了对比,采用SEM和XRD分析进行微观性能测试。研究结果表明:硫铝酸盐水泥基混凝土抗碳化能力随着水灰比的减小而增加;随着标准养护龄期的延长而增大;掺合料的加入可以提高其抗碳化能力,其最佳掺量为20%。相同条件下,硫铝酸盐水泥基混凝土抗碳化能力高于普通硅酸盐水泥基混凝土抗碳化能力。The paper studies influence of resisting carbonization of concrete of sulphoaluminate cement at different water-cement ratio, at the different standard under the conditions of conservation intensity, at different dosage of admixture. And it compare with resisting carbonization of concrete of portland cement. And the methods of SEM and XRD are adopted in analyzing microcosmic performance. Results show that resisting carbonization of concrete of sulphoaluminate cement increases if water-cement ratio decreases, increases if standard conserve time is more; And the admixture makes resisting carbonization of concrete of sulphoaluminate cement more, but the most dosage of the admixture is 20% of cement. In addition, resisting carbonization of concrete of sulphoaluminate cement is more than resisting carbonization of concrete of portland cement at the same addition.
