Excavation silt solidified soil, preparation method and application
The invention relates to the technical field of road engineering materials, and provides excavation silt solidified soil, a preparation method and application, the silt comprises sandy silt and clayey silt, the silt solidified soil comprises, by mass, 50-76% of silt, 4-10% of a soil body curing agent and 20-40% of auxiliary material soil and water, the silt solidified soil is formed by mixing and rolling silt, a soil body curing agent, auxiliary material soil and water. Water is added, so that the water content of the solidified soil mixture system is 2% larger than the optimal water content, and mechanical compaction is facilitated. The auxiliary material soil is doped, the content of clay particles in excavated silt is supplemented through the auxiliary material soil, the soil material particle gradation is optimized, the effect of the curing agent is better played, the purposes of reducing the content of the curing agent and improving the performance of the cured soil are achieved, the particle size of the particles is updated through the auxiliary material soil, and the particle gradation of a mixture system can be changed. And in addition, the clay particles are mainly secondary minerals with relatively active properties, so that the effects of the ionic curing agent and calcium oxide can be better exerted.
本发明涉及道路工程材料技术领域，提供一种开挖粉土固化土、制备方法及应用，所述粉土包括砂质、黏质粉土，按质量百分比计，所述粉土固化土包括：50～76％粉土、4～10％土体固化剂和20～40％辅料土和水，所述粉土固化土由粉土、土体固化剂、辅料土和水混合碾压成型。添加水使固化土混合物体系含水率比最优含水率大2％，便于机械压实。通过掺入辅料土，通过辅料土补充开挖粉土中黏土颗粒的含量，优化土料颗粒级配，更好的发挥固化剂作用，实现降低固化剂含量，提升固化土性能的目标，通过辅料土更新颗粒粒径，可以改变混合物体系的颗粒级配。另外黏土颗粒主要为性质比较活跃的次生矿物，更能发挥离子型固化剂的和氧化钙的效果。
