Effect of Steel Fibers on Compressive Strength of Recycled Aggregate Concrete

Abstract In this research article effect of steel fibers on workability and compressive strength recycled aggregate concrete is presented. Recycled aggregates from demolished waste were used in equal proportion with conventional aggregates. Steel 1 mm diameter 25 length used. For preparation 1:2:4 mix 0.55 water-cement ratio was Workability each checked by slump cone test. Total 40 samples prepared standard way cured for 28 days. All the specimens tested maximum load universal testing machine under gradually increasing at rate 0.5 kN/sec. Recorded converted into strength. The obtained results showed that decreased increase dosage than concrete. Compressive observed 15% 34% higher fiber 3%. It evident although addition reduces but binary blending not only overcomes loss shows gain fibers.
