摘要:
The beneficial reuse of cement-treated waste sludge in construction sector is an intractable challenge in the context of sustainable development. To exploit the potential of magnesium oxychloride cement (MOC) as cementing binder in substitution for Portland cement, various inorganic/organic additives are imported to overcome the key defect of MOC – instability in water and improve the water resistance of MOC solidified sludge. To achieve this goal, the mechanical and microstructural studies by compressive strength, water immersion, shear stren...
