    Abstract
  • During pipe jacking construction, a large amount of silt will be generated, which has characteristics such as high moisture content, poor stability, and uneven particle distribution. Mud solidification technology is an important means for the reuse of construction waste. To improve the strength of mud consolidation and explore the efficient formula of stabilizing agents, sand strength tests, unconfined compressive strength tests, X-ray diffraction analysis, specific surface and pore size analysis tests, FTIR Fourier transform infrared spectroscopy analysis were used to detect the strength of stabilizing agents and consolidation bodies. The changes in the composition of consolidation bodies, internal porosity changes, and molecular bonds in the microstructure were studied. The results show that using construction waste, phosphogypsum, and slag as raw materials, a ratio (top pipe sludge: construction waste: phosphogypsum: slag=0.40:0.55:0.015:0.052) was selected to meet the strength requirements of domestic solid waste base materials for road subgrade. After 28 days of curing, the moisture content of the samples was 1.32%～2.89%, and the compressive strength was 3.3～6.6 MPa.
