Effect of steel fibre content with high strength fibre reinforced concrete on compressive behaviour

Abstract

The purpose of this study is to determine performance of compression behavior with steel fibre reinforced concrete (FRC). The compression test was tested by using a cube sample of 100 mm3; and the results were analyzed to determine the compressive strength, elastic modulus and HSFRC crack pattern. This paper analyses the three different mixture of high strength fibre reinforced concrete (HSFRC) which has a compressive strength of 60-85MPa containing 0.5-1.5% volume of steel fibre. HSFRC results show that the compressive strength of 0.5% steel fibre volume at 28 days is 82.1MPa. Therefore, the use of low steel fibre volume can increase compressive strength from the control sample (CS). This clearly shows that the low steel fibre volume has improved the mechanical properties of compressive strength. Based on the experimental data, HSFRC’s compressive strength has suggested good results than without steel fibre (HSC). It has been found that the addition of fibre causes more ductile than without fibre.
