Abstract - The experimental investigation on the
incorporation of Incinerated Sewage Sludge Ash (ISSA) into concrete mixes has yielded significant insights into its impact on workability, mechanical properties, and durability. The primary objective was to evaluate the impact of ISSA on the slump and workability of fresh concrete mixes. Results showed that the inclusion of ISSA up to 30% resulted in a slight increase in workability, with the slump value reaching its peak at 10% ISSA (75 mm). Beyond this point, the slump values stabilized or slightly decreased, indicating that ISSA content up to 30% does not adversely affect workability. To assess the influence of ISSA on the mechanical properties of hardened concrete, including compressive, flexural, and tensile strength. Compressive strength tests revealed a general decline with increasing ISSA content. The normal mix (0% ISSA) reached 30 MPa at 28 days, while Mix 1 (10% ISSA) exceeded this, achieving 31 MPa. However, higher ISSA content resulted in reduced compressive strengths, with Mix 4 (40% ISSA) showing the lowest at 26 MPa. Flexural and split tensile strength tests mirrored these results, with Mix 1 (10% ISSA) closely matching or slightly surpassing the normal mix, while higher ISSA contents led to progressively lower strengths.

1. INTRODUCTION
1.2 Applications of ISSA in Concrete
Concrete is amongst broadly utilized construction materials globally, primarily comprises of cement, water, and aggregates (sand, gravel, or crushed stone). Over time, researches have been conducted for enhancing its properties and sustainability by integrating various SCMs. Amongst is Incinerated Sewage Sludge Ash (ISSA), derived from the incineration of sewage sludge. ISSA is a by-product obtained from the incineration of sewage sludge, which is the residual, semi-solid material produced as a by-product of wastewater treatment processes. The incineration process reduces the volume of sludge and converts it into ash, which can then be used in various applications, including as an SCM in concrete.

pozzolanic reaction, enhancing compressive strength of concrete over time. Durability The incorporation of ISSA in concrete improves its resistance to sulfate attacks, chloride penetration, and other chemical attacks, enhancing the overall durability of the concrete. Reduced Permeability ISSA can reduce the permeability of concrete, decreasing the risk of water ingress and subsequent deterioration due to freeze-thaw cycles or other environmental factors. Waste Management Utilizing ISSA in concrete provides a sustainable solution for disposing of sewage sludge, reducing the environmental impact of waste management. Cost Savings ISSA can partially replace traditional cement and aggregates, potentially lowering material costs in concrete production. Sustainability By using ISSA, mandate for natural sources like limestone (used in cement production) and natural aggregates is reduced, promoting more sustainable construction practices. Thermal Conductivity The inclusion of ISSA could enhance thermal insulation properties of concrete. 3 Low thermal conductance implies better thermal insulation, making buildings more energy-efficient by reducing the need for heating and cooling.

General Construction ISSA can be used in various types of concrete for general construction purposes, including residential, commercial, and industrial buildings. Road Construction It can be utilized in the construction of roadways, including pavements, sidewalks, and other infrastructure projects. Precast Concrete Products ISSA can be used in the production of precast concrete products such as blocks, pipes, and panels. Marine Structures Due to its enhanced durability and resistance to chemical attacks, ISSAincorporated concrete is suitable for marine structures exposed to harsh environments.
