• Reviewed the valorization of different sludge and sludge ash in construction materials.
• Sludge can be recycled as alternative fuels and raw materials to produce eco-cement clinkers.
• Aluminosilicates in sludge/sludge ash improved the properties of construction materials.
• Sludge/sludge ash-derived function concrete, bricks and ceramic exhibit good qualities.
• Potential toxic elements in sludge/sludge ash could be effectively immobilized.
