The Effect of Size of Aggregates and Nano Silica Dosage on the Fresh Properties of Self-Compacting Concrete

Ravi U, Krishna Chaitanya B

This work aimed to investigate effecting of using nano silica as partial replacement of fine aggregate, on the fresh characteristics of self-compacting concrete (SCC). For this purpose, different self compacting concrete mixes were designed at constant water - to - binder ratio of 0.50 and 425kg/m^3 of binder content. Class F fly ash was used as partial replacement of cement (30 %by weight of cement). The three designed nano silica contents of 0, 1 and 2 % on each percentage of nano silica content we have to change in aggregate variations NSA, NSB, NSC were considered as experimental parameters. The workability properties of self-compacting concrete mixtures were performed regarding to slump flow diameter, T 500 slump flow time, V-funnel flow time, L-box height ratio. The experimental results of the work are showed that the nano silica with the sizes and contents that used in this work can be used successfully as a fine aggregate in self-compacting concrete.
