  • Reuse of Textile ETP Sludge as Construction Material

    The use of textile ETP sludge in reinforced cement concrete will corrode the reinforcements due to its corrosive properties. So, sludge can only be used in plain cement concrete specimens. The sludge mixed building specimens like mortar bricks and hollow blocks can be used in construction of partition walls and compound walls. The textile ETP sludge mixed pavement blocks can be used in ...

    The hardened RM-GBFS-based geopolymer concrete consisted of geopolymeric gel, C-S-H gel with a low Ca/Si ratio and some raw red mud particles. The main reason for the significant adsorption of heavy metal ions of RM-GBFS-based geopolymer pervious concrete may be that the geopolymeric gel and the C-S-H gel with a low Ca/Si ratio have large surface area and high pore volume, and the unreacted ...
