Investigation Of Adama Industrial Park?��?S Dried Sludge Powder As A Partial Cement Substitute In Concrete Mixes

Abstract

The Increasing Generation Of Industrial Wastewater Sludge, Such As That From The Adama Industrial Park, Presents A Significant Environmental And Economic Challenge, While Conventional Cement Production Remains A Major Contributor To Global Carbon Emissions. This Study Investigate The Potential Valorizing Dried Sludge Powder(Dsp) From The Adama Industrial Parks?��? Wastewater Treatment As A Partial Replacement For Ordinary Portland Cement(Opc) In Concrete Mixes, Aiming To Develop Sustainable Construction Materials. The Research Systematically Characterized The Physicochemical Properties Of Dsp, Including Its Chemical Compositions, Heavy Metal Content, And Fineness. Concrete Mixes Where Prepared With Dsp Substituting Opc At 0%, 5%,10%,And 15% By Weight ,Followed By Comprehensive Testing Of Fresh(Workability) And Hardened (Compressive, Flexural Strength, Water Absorption, And Sulfate Attack) Properties At 7 And 28 Days Of Curing. Microstructural Analysis Using Scanning Electron Microscopy (Sem) And Energy Dispersive X-Ray (Edx) Spectroscopy Was Also Conducted. Results Indicate That Increasing Dsp Content Generally Enhanced Concrete Workability. While Both Compressive And Flexural Strength Decreased With Higher Dsp Percentages, Statistical Analysis (Two-Way Anova) Confirmed These Significant Impacts. Notably, 5% Dsp Replacement Yielded Acceptable Compressive Strengt
