Abstract
In the present study, mechanical properties of self compacting concrete containing fly ash and silica fume as cement replacements are investigated at different ages of curing. Mechanical properties of specimens were examined at 7, 28 and 120 days for compressive strength and 28 days of curing for tensile strength. So as to reach self compatibility, different tests were carried out on fresh concrete such as slump flow test, T50, J-Ring, V-funnel and L-Box test. Self compacting mixtures had a cement replacement of 20, 30 and 40% with class F fly ash and 5, 10 and 15% with silica fume. The results show that normal strength self compacting concrete could be successfully produced using fly ash and silica fume.
