The increasing population and modern lifestyle demand have caused the increase in waste sludge production gradually at the same time causing environmental pollution. Thus, the idea of reusing this waste sludge emerges as an alternative way of reusing it to create a product instead of disposing it. The Naphthalene sludge, a by-product obtained from the production of superplasticizer, also known as concrete admixture, is used in this study as an additive in concrete. Concrete was produced with 0%, 1%, 2% and 3% additive of the naphthalene sludge and the workability and strength of mortar and concrete were studied to investigate the effect of the waste sludge on concrete. Samples for compressive strength test were prepared with fixed water-cement (w/c) ratio of 0.50 and cured for 7 and 28 days. The results showed an increase of concrete and mortar strength when the waste sludge addition is increased. 3% of Naphthalene sludge additive shows the highest concrete strength based on the 28 days strength and obtained the best workability among the control sample and the other 1% and 2% of additive. By adopting sustainable practices in waste management and innovation can mitigate adverse impacts while supporting global sustainability development goals (SDG) 2030.
