In any industrial or municipal population areas, the excess sewage sludge produced by wastewater treatment plant WWTP creates significant problems due to its growing quantity and possibly containing toxic materials or heavy metals. The concrete industry is one of the fields where wastewater sludge, as well as other wastes, could be utilized inefficient way. The inclusion of wastewater sludge in materials incorporated with cement reduces some of the costly and high energy stages of usage, and the obtained product is often safe and stable. Several studies promoted that the reuse of sludge in concrete can be an ideal solution to get rid of its negative effects, especially the hazardous ones, as it is an effective alternative to reuse the sludge for land applications. The main aim of this study is to present the recent methods of utilizing wastewater dried, dehydrated, and/or raw sludge in concrete industries. The present review revealed the difficulty of choosing the most general technique of utilizing sludge in the concrete industry, due to its various physical and chemical properties.
