Targeting the national disposal requirements of "reduction, stabilization, harmless treatment, and resource utilization" for large-scale river dredged silt, this study adopts the disposal strategy of "dehydration first, solidification second" to investigate the effect of organic matter content on the chemical composition and micro-pore structure characteristics of cement-solidified silt, and reveals the inhibitory mechanism of organic matter on cement solidification reactions. Based on the formation principle and conditions of ettringite chemical reactions, and utilizing the dual-compatibility technology combining high-activity mineral admixtures and chemical admixtures, a novel solidification material for organic-rich river channel silt based on rapid ettringite formation is developed. The environmental characteristics of silt solidified by this novel material and their variation rules with curing age are studied, and a solidification material with balanced engineering and environmental protection performance is developed by incorporating additives. The dataset mainly includes: a series of indoor mechanical property tests and microscopic mechanism analysis conducted to explore the impact of organic matter on the physical and mechanical properties of raw silt and solidified silt; a full solid waste-based solidification material suitable for high-water-content organic-bearing silt, developed based on the rapid ettringite formation principle with compressive strength as the performance indicator; a series of microscopic characteristic analyses carried out to clarify the strength growth mechanism of solidified silt; a series of outdoor leaching tests under natural rainfall conditions performed to investigate the environmental characteristics of silt solidified with industrial waste residues. The dataset covers original experimental record data, charts, graphs, spectra, the appraisal report of the novel solidification material, 6 corresponding academic papers and 3 patents, corresponding to assessment indicators 1.1 and 1.2. The total data volume is 81.18 MB.
