To ameliorate the physic-mechanical behavior of waste sludge at reasonable costs, fly ash and silica fume are incorporated in MKPC-based solidification, and the impact of MKPC-mineral additive is comprehensively examined from the multi-viewpoint of compaction, strength, permeability and compressibility. The micromorphology of solidified sludge is identified by SEM tests. The results show MKPC-mineral additive has an excellent ability to improve the strength and deformation property of sludge under the influence of MKPC content, mineral additive content, curing age and compaction degree. MKPC c...
