Abstract: During the period between 1990 to 2017, self-compacting concrete (SCC) has been developed to reduce workmanship errors and improve the durability of the concrete. Despite many benefits of the self-compacting concrete, its cost still remains high, due to the high proportion of the cement required. To mitigate this issue many researchers urged the use of mineral additions as partial replacement of the cement. On the other hand, the management of the solid waste is a global concern in every country nowadays. The fact that there currently lacks a universally acceptable strategy for recycling ceramic waste is significant. The physical and chemical properties of the waste ceramic make it suitable for the concrete production. This study assessed the effect of partial replacement of the cement the limestone filler (LF) at 0%, 10%, 15%, 20%, and 25% and replacement of the natural coarse aggregate with the waste ceramic tiles aggregates (WCTA) at 25%, 50%, 75%, and 100% within the validity range of self-compacting concrete properties at the fresh state. Sika Viscocrete 3088 was used to assess the saturation dosage of the superplasticizer. The flowability, viscosity, passing ability and resistance to segregation of self-compacting concrete containing the limestone filler and waste ceramic tile aggregates were assessed. The results showed that the saturation dosage of the superplasticizer Sika Viscocrete 3088 is 0.07% in solid content. Furthermore, high proportion of waste ceramic tile aggregates (75%) with optimum percentage of limestone filler (20%) satisfy the properties of SCC in the fresh state.
