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。 In order to improve the performance of plain soil building materials of traditional adobe masonry dwellings, the modified soil materials were formed by blending wheat straw, quicklime and grit respectively in plain soil, and 100 mm × 110 mm Three kinds of blend cylinder test blocks. Based on the test results and the compressive strength of the test pieces, the trend of the histogram of the intensities of the test pieces with different blending amounts was analyzed. The optimum range of blending proportions of wheat straw, quicklime and coarse sand respectively was proposed.
