The study aims to produce concrete using various percentages of hypo-sludge ash (HAS) in place of cement. The waste paper sludge ash is composed of magnesium oxide and calcium oxide. Therefore, it can be tested as an innovative cement replacement, providing a solution for traditional concrete. For this study, the various proportions of ash used are 5%, 10%, and 15% by weight of cement. The mixed design carried out was as per the Indian standard code. The ingredients used for concrete making are cement, aggregates, hypo sludge ash (HSA), superplasticizer, and water. A test mix was carried out to check the behaviour of a concrete mix, and its physical and hardening properties were checked. Cube samples were cured for 3, 7, 14, and 28 days to check hardening properties. Experimental analysis shows that by replacing 5% cement with HSA, the strength results obtained are close to the reference concrete. [ABSTRACT FROM AUTHOR]
