Riverway sludge-based engineering soil and preparation method thereof
The invention discloses riverway sludge-based engineering soil, which is prepared from the following components in percentage by weight: 53-83% of riverway sludge, 10-30% of construction waste powderslag, 5-10% of fly ash and 2-7% of cement, wherein the water cement ratio is controlled to be 0.1-0.5. According to the invention, riverway dredging silt is used as a main raw material, construction waste powder slag is used as fine aggregate, and a small amount of cementing materials such as fly ash and cement are used as auxiliary materials, so that the mechanical property and the stability of an obtained consolidation system can be effectively ensured so as to form riverway silt-based engineering soil meeting the requirements of soil for road filling, bulk disposal and resource utilizationof river dredging silt can be achieved, land is saved, pollution to the environment is avoided, and important economic and environmental benefits are achieved.
本发明公开了一种河道淤泥基工程土，各组分及其所占制备百分比包括：河道淤泥53～83％，建筑垃圾粉渣10～30％，粉煤灰5～10％，水泥2～7％；同时控制水灰比为0.1～0.5。本发明以河道疏浚淤泥为主要原料，建筑垃圾粉渣作为细骨料，并辅以少量粉煤灰和水泥等胶凝材料，可有效保证所得固结体系的力学性能和稳定性能，进而形成满足道路填垫用土要求的河道淤泥基工程土；可实现河道疏浚淤泥的大宗处置及资源化利用，节约土地、避免对环境的污染，具有重要的经济和环境效益。
