Due to low water-cement ratio of self-compacting concrete (SCC), the concrete tends to be brittle. The inclusion of crumb rubber as aggregate replacement in SCC mixture has been proven to increase the properties of the SCC. Despite that the addition of the crumb rubber reduced the mechanical properties such as compressive strength, flexural strength etc. Therefore, this study is carried out to evaluate the physical performance of rubberized self-compacting concrete (R-SCC) with inclusion of nano-silica. The slump flow test, L-Box test and V-Funnel test were carried out and indicated that the flowability and viscosity of the R-SCC increase with the inclusion of fly ash and with the addition of nano-silica. The inclusion of nano-silica into the mixture improved the flowability of the concrete as well as the slump flow spread. The addition of 2 of nano-silica into the R-SCC mixture improved the passing ability of the concrete which consider the optimal addition percentage. © 2021 American Institute of Physics Inc..
