Abstract
This chapter presents the characterization of incinerated sewage sludge ash (ISSA), including its physical and chemical properties. Then the lime-pozzolan cement with the inclusion of ISSA is introduced, followed by an explanation of adsorption mechanisms by ISSA. The utilization of ISSA in concrete-related applications and ceramics covering mechanical properties and durability is also summarized. Last but not least, the application of ISSA sometimes being used with cement or lime on the stabilization and solidification of soft soil with respect to the geotechnical properties of treated soil, such as unconfined compressive strength, swelling potential, and shear strength, are discussed. Recycling of ISSA either by reusing it for manufacturing of construction materials or by applying it for stabilization/solidification of soil or sediments reduces the consumption of natural resources, enables sustainable waste management, cuts down the carbon footprint, and alleviates landfill burden and cost.
