中文摘要	为研究硅粉掺量对沙漠风积沙水泥基材料性能的改善效果,设计不同硅粉掺量的单因素试验进行稠度测试和抗折抗压强度测试,分析了硅粉掺量对材料稠度和力学性能的影响。结果表明:沙胶比为3,硅粉掺量为6%时,材料3 d、7 d抗压强度较基准组分别提高了61.9%、 47.1%,28 d抗压强度较基准组提高了38.2%,此时折压比较大,为0.33,沙漠风积沙水泥基材料的抗压性能显著提高,且脆性较小。前期水泥基材料抗压强度增长率随硅粉掺量的增加先增大后减小,后期抗压强度增长率随硅粉掺量的增加而增大;水泥基材料抗折强度增长率随硅粉掺量的增加先增大后减小,当硅粉掺量大于10%时,材料抗折强度增长率为负,掺入过量硅粉会降低沙漠风积沙水泥基材料的抗折强度。
英文摘要	In order to study the effect of silicon powder content on the performance of cement-based materials for aeolian sand in desert, a single factor test with different silicon powder content was designed for consistency test and flexural compressive strength test, and the change rule of silicon powder content on the material consistency and mechanical properties was analyzed. The results show that when the sand binder ratio is 3 and the silica powder content is 6%, the compressive strength of 3 d and 7 d is 61.9% and 47.1% higher than that of the reference group, respectively, and the compressive strength of 28 d is 38.5% higher than that of the reference group. At this time, the flexural pressure ratio is 0.33. The compressive performance of desert aeolian sand cement-based materials is significantly improved, and the brittleness is small. In the early stage, the increase rate of compressive strength of cement-based materials increases first and then decreases with the increase of silica powder, while in the later stage, the increase rate of compressive strength increases first and then decreases with the increase of silica powder; when the amount of silica powder is greater than 10%, the increase rate of flexural strength of materials is negative, and the excessive addition of silica powder will reduce the aeolian sand in desert Flexural strength of cement-based materials.
