Preparation method of waste rubber metakaolin cement soil
The invention relates to a preparation method of waste rubber metakaolin cement soil, which comprises the following steps: preparing a NaOH solution in advance, drying and crushing undisturbed soil, sieving with a 2mm screen to obtain dry soil, weighing waste rubber particles accounting for 2.5% of the mass of the dry soil and cement accounting for 12% of the mass of the dry soil, uniformly mixing the dry soil, the waste rubber particles and the cement, and uniformly stirring to obtain the waste rubber metakaolin cement soil. Adding water into the mixture according to the optimal water content of the soil, standing for 15 minutes, weighing metakaolin accounting for 3% of the mass of dry soil, adding the metakaolin into the mixture, weighing a NaOH solution, and adding the NaOH solution into the mixture to obtain the waste rubber metakaolin cement soil. The method has the characteristics of simplicity, convenience in operation and the like.
本发明涉及一种废弃橡胶偏高岭土水泥土的制备方法，提前配置NaOH溶液，将原状土经烘干和粉碎处理后，过2mm筛网，得到干土，称取2.5％干土质量的废弃橡胶颗粒和12％干土质量的水泥，将干土、废弃橡胶颗粒和水泥拌和均匀，然后按土的最优含水率将水加入拌合物中，静置15min，称取3％干土质量的偏高岭土，将其加入拌合物中，称取NaOH溶液，加入拌合物中，得到废弃橡胶偏高岭土水泥土，本发明具有方法简单、操作方便等特点。
