This paper aims to evaluate the effect of sewage sludge ash (SSA) and cotton stalk Ash (CSA) as a replacement ratio by weight of cement content on self-compacting concrete (SCC). SSA and CSA were seperately used as a partial replacement of cement in concrete mixes. The produced concrete mixes were experimentally tested via various mechanical and physical tests such as compressive strength, water absorption etc. SSA and CSA were sieved through sieve size of 90µm, and added to the concrete mixes with 5,10and 15% as cement replacement of cement content. 2% of a superplasticizer and 1% of viscosity modifying agent was added to the concrete mixes. The concrete mixes containing 5 and 10% of CSA and 2.5 and 5% of SSA as cement replacement showed increments in compressive strength compared to control mix at the age of 28 days. The increments were 4.29, 10.05% and 0.55, 5.36% for CSA and SSA mixes, respectively. Water absorption of SSA and CSA concrete samples also showed a decrease in water absorption percentage compared to control concrete samples. Therefore, SSA and CSA were found to have the potential to be used as partial cement replacement in making SCC, which leads to impact on solid waste management in landfill process.
