Abstract

The use of pozzolanic materials as a replacement for cement is nowadays of great significant due to the improvements gained in the properties of cement-based materials and the costs it saves. On the other hand, sewage sludge is harmful to both the environment and the human health and its safe disposal is highly desirable.Based on these considerations, this study investigates the use of SEWAGE SLUDGE ASH as an artificial pozzolan to produce self-compacting cement-based materials, an initiative that has come to be evaluated as a revolution in the concrete industry. The objective of the study is to accelerate the performance of SEWAGE SLUDGE ASH by utilizing nano-silica particles. For this purpose, 10 mix designs were employed for self-compacting mortar and concrete made up of binary and ternary cementitious blends of SEWAGE SLUDGE ASH (0%, 5%, 10%, 15%, and 20%) and nano-silica (0% and 1%). The results show that the rheological and mechanical properties of the samples declined as a result of adding SEWAGE SLUDGE ASH, but their durability characteristics improved with only small percentage volumes of SEWAGE SLUDGE ASH addition. Moreover, nano-silica addition was observed to improve the mechanical properties and durability of self-compacting mortar and concrete. Finally, the reactivity of SEWAGE SLUDGE ASH increased and its performance was improved in the presence of nano-silica.
