Today, the construction industry is witnessing rapid growth, and the number of ongoing construction projects is increasing, which has led to an increase in the demand for construction necessities such as paving blocks. The surge in activity raises concerns regarding preserving natural resources even if it also represents an important development in the construction industry. This research investigates the incorporation of Textile Dyeing Effluent Sludge (TDES) into green paver blocks, aiming to determine the mechanical properties, including density, compressive strength, and water absorption, and to analyse the optimum percentage mix ratio of TDES admixture in Green Paver Block. The study examines paver blocks with varying TDES content compared to control blocks made from natural sand and Ordinary Portland Cement (OPC). The density test assessed the mass per unit volume, crucial for evaluating compactness, porosity, and structural integrity, using precise weighing and volume calculation methods. The compressive strength test, following BS EN 12390-3:2009 standards, measures the load-bearing capacity of the blocks, focusing on TDES proportions and structural strength, indicated by cracking under a gradually applied load. The water absorption test evaluates the blocks' resistance to moisture, essential for durability, by measuring absorption percentages after water immersion. Results prove that blocks with 5-10% TDES content exhibit mechanical properties comparable to control blocks, while higher TDES percentages may be suitable for less structurally demanding applications. This comprehensive evaluation will be help in identify optimal TDES mix ratios, advancing sustainable construction practices, and contributing to innovative waste management strategies in the textile industry.
