Assessment of the Polypropylene Fiber Reinforced Concrete with Wastewater Lime Sludge

Abstract

The study investigated by the reuse of wastewater lime sludge is replaced for cement and addition of polypropylene fiber in the production of concrete for external use. The textile wastewater covers the cotton dyeing and printing operations. Nowadays the demand of cement has concern increased. This will contribute to increased cement production because of the cement industry is one of the major subscribers of carbon dioxide emission [15-18]. This work is directed towards developing low cost concrete from wastewater treatment plant. The study utilized in the sludge-cement replacement percentages of 10%, 20%, 30%, 40% and 50% by weight of cement. The test conducted on concrete examines were slump test, compaction factor test and then the mechanical properties on cube, cylinder, Beam and also NDT tests. Finally, the study concluded that the dry sludge can be used in as an improver to concrete mixture till up to 30%. Many more researches are needed to evaluate the durability of sludge concrete and the performance of reinforced sludge concrete.
