Steel Fibre Effects on Mechanical Performance and Toughness of Steel Fibre Reinforced High Strength Concrete Following Normal and Hygrothermal Curing (SFRHSC)

Abstract

The mechanical toughness and durability of SFHSC were examined in this work Results were collected at 7 days and 7 days plus 24 hours in the experimental research which tested the properties of steel fibre high pressure concrete using two types of drying dictatorships conventional water curing and hysteretic drying Five eight ten eleven and thirteen percent volume concentrations of steel fibres were added Utilizing compressive and flexural testing the flexibility modulus test the ultrasonic pulse experiment the flow test the air coefficient of permeability test and the permeability trial mechanical property and toughness were identified The compressive and flexural values of the steel slag high performance concrete reached a peak of 76 MPa and 1482 MPa respectively after conventional curing for the 30 percent volume fraction of steel slag According to the trials conducted for this study adding steel fibres to elevated concrete that has been treated with regular water rather than hygrothermal water improves mechanical durability
