Abstract The efficient disposal of sediment in river and lake environmental control engineering has become an important problem of environmental control. The grouting reinforcement method commonly used in geotechnical engineering needs a large number of grouting materials. Considering the difficult problem of sediment disposal and the demand for grouting materials in geotechnical engineering，this paper proposes to study geopolymer grouting materials with pure sediment as the basic material. Taking Wuhan South Lake to produce sediment dredging engineering as raw material，based on analyzing the basic properties of the sediment，this paper combines alkali excitation and thermal activation method of sediment base polymer preparation experiment. On this basis，the orthogonal experiment is carried out to explore the alkaline exciting agent module，alkali equivalent，water cement ratio，and other factors that influence on the strength of sediment mass base polymer. The strength of the prepared base polymer reaches 16.37 MPa in 28 days. X-ray diffraction(XRD) and Fourier transform infrared spectroscopy(FTIR) reveal the formation process of geopolymer gel. The results show that under the combined action of alkali excitation and thermal activation，the preparation of sediment base polymer is feasible and can meet the engineering needs. This method can not only solve the problem of disposal of a large amount of sediment but also provide a low-carbon green cementitious material for engineering construction.
