Biochar modified silt and preparation method thereof
The invention discloses charcoal modified silt and relates to the technical field of silt modification, and the doping amount of charcoal in silt is 1-12% by mass. The preparation method of the charcoal modified silt comprises the following steps: drying silt; mixing the corn straw biochar with dry silt, so that the biochar is uniformly dispersed in the silt, and the doping mass percentage of the biochar in the silt is 1-12%; adjusting the water content of the mixture with the charcoal to the optimal water content; and sealing and curing the mixture with the charcoal, so that the moisture is uniformly distributed, and the modification of the silt is completed. According to the method, the silt is modified by adopting the corn straw biochar, so that the disintegration rate of the silt is effectively reduced, the disintegration time of the silt is prolonged, and the method is of great significance to prevention and treatment of roadbed disasters caused by humidification disintegration in silt areas.
本发明公开了一种生物炭改性粉土，涉及粉土改性技术领域，按质量百分比计，粉土中生物炭的掺杂量为1~12%。生物炭改性粉土的制备方法包括：将粉土烘干；将玉米秸秆生物炭与干燥粉土拌合，使得生物炭在粉土中均匀分散，且使得粉土中生物炭的掺入质量百分比为1~12%；将与生物炭的混合物调整为最优含水率；将与生物炭的混合物密封养护，使得水分均匀分布，完成粉土的改性。本发明采用玉米秸秆生物炭改性粉土，有效降低粉土的崩解率，延长粉土的崩解时间，对于防治粉土地区由于湿化崩解造成的路基灾害具有重要的意义。
