Abstract:
In order to properly deal with and utilize the waste mud produced by geotechnical engineeringconstruction, the selection of raw materials and the basic performance test of materials are firstcompleted, and then the multi?factor test design is carried out. The influence of different cement andbasalt fiber content on the mechanical properties of waste mud modified materials is studied by unconfinedcompressive strength tests, and the modification mechanism of waste mud is analyzed from themicroscopic point of view by scanning electron microscope （ SEM ） tests. Finally, the practicalengineering application research is carried out according to the test results, and the application effect isverified. The test results show that the addition of cement and basalt fiber can effectively improve themechanical properties of waste mud modified materials, and the compression deformation stage ofmodified materials is effectively shortened after adding basalt fiber. Microscopically, cement and mudparticles form cemented agglomerates, and basalt fiber connects cemented agglomerates and mud particlesmore effectively to form a closer overall structural unit.
