摘　　要：为改善传统土坯砌体民居的素土体建筑材料的性能,通过在素土中分别掺和麦秸秆、生石灰和粗砂,形成改性土体材料,制作了不同掺和量的100 mm×110mm 3种掺合物圆柱体试块。通过试块抗压强度的试验现象和结果,分析不同掺和量试块强度的柱状图的变化趋势,提出分别掺和麦秸秆、生石灰和粗砂试块的最佳掺和比例范围。To improve the pertbrmanee of the prime soil building materials of the traditional adobe masonry residential areas, wheat straw, lime and coarse sand were added respectively to prime soil, and formed modified soil materials. Cylinder test columns with the 3 mixed materials and different l）lending amounts were construeted and their sizes were all 100 mm×110 mm. By the experiments of the cylinder test compressive strength, this paper analyzes the trend by bar eharts of the differen! amounts of strength cylinder test colunms, and proposes optimal blending ratio ranges for wheat straw, lime anti coarse sand bh）ck, respectively.
