Substitution of Cement with Non-metallic Municipal Solid Wastes in Pavement Blocks
Purpose: This study to ascertain the production of pavement bricks using a binder produced from MSW processing. It seeks to examine the properties of pavement bricks made from different mixing ratios of MSW binder and sand in comparison to pavement blocks made from commercially available cement. Design/ Methodology/ Approach: Plastic portion of MSW (P-MSW) were shredded and the organic fraction of municipal solid wastes (OFMSW) were dried and milled into fines. The shredded plastics were melted and the OFMSW and sand are added and stirred to form a uniform paste using the hand mixing method. The hot paste was poured into moulds and allowed to cool to form pavement blocks. The sand was 30%, 40%, and 50% proportions of the brick mixtures with the remainder being P-MSW and OFMSW of equal fractions. The water absorption, compressive strength and x-ray diffraction of pavement bricks produced were analysed and the results obtained were compared to that of normal cement bricks (NCB). Findings: The NMMSW paver bricks had better water absorption resistance than NCB. This quality makes the NMMSW paving blocks suitable for use in damp areas. NMMSW paver bricks of 50% sand (25% OFMSW and 25% PW), C50, gave a better compressive strength that is 16.4 N/mm2 than 40% (C40) and 30% (C30) sand paver bricks but less than the compressive strength of NCB. XRD analysis done shows that NMMSW and sand-cement pavement brick have similar mineral compositions. Practical Implications: This study seeks to reduce these environmental problems caused by enormous generation of wastes by using Non-metallic MSW (NMMSW) as a full replacement for cement in pavement blocks. Also, reduction of production cost of paver bricks for walkways along major road by partial or fully substituting cement with readily available wastes Social Implications: This study seeks to reduce environmental problems posed by the ever-growing municipal solid wastes generation by using non-metallic MSW (NMMSW) by introducing a low cost waste management technology. Originality and Value: This study contributed to the pool of knowledge on how recycle our waste into useful products.
