【摘要】 为改善新疆地区传统土坯砌体民居的素土体建筑材料的性能,通过在素土中掺和麦秸秆或粗砂,形成改性土体材料.参照混凝土抗压试验标准,制作了4种尺寸素土体材料的立方体抗压强度试验试块,并制作了边长100mm的改性土体材料立方体试块.通过试块的抗压强度试验对比分析,研究其抗压强度和变形能力,提出了掺和麦秸秆和粗砂的最佳比例范围.试验结果表明,在素土中掺和麦秸秆或粗砂,可提高抗压强度和极限位移.更多还原

【Abstract】 To improve the properties of traditional earth building materials in Xinjiang,stabilizers such as straw or coarse sand were added to raw soil so as to generate modified soil materials. Based on the standards of concrete compression tests,cubic raw soil specimens of four sizes and modified soil material specimens with a side length of 100 mm were prepared. Through comparative analysis of compression tests of specimens,their compressive strengths and deformation capacities were studied. An optimum ratio of additives such as straw and coarse sand is recommended. The test results indicate that appropriate additives of straw or coarse sand added to raw-soil materials can improve their compressive strength and deformation capacity.更多还原
