- Abstract
The High performance concrete (HPC) study is to determine various types of material effects at a high temperature with content of Brass coated steel fibers (BCSF) effects on the workability, ductility enhancement of concrete. Various mixture of concrete was prepared and tested using various types and sizes of BCSF at the designed compressive strength of concrete of 80 to 100 MPa. The post-cracking tensile strength (>5 MPa). BCSF is HPC concrete for fire resistance, strengthening of existing structure and retrofitting. BCSF can improve the compressive strength of concrete, including tensile, and flexural strength, shear strength, crack resistance etc. Fire resistance is a compulsory design parameter that must be considered during selecting materials. The combination use of BCSF indicates that the residual engineering properties after being exposed to high temperatures is higher for concretes with the addition of steel fiber than the conventional concrete. The incorporation of BCSF into concrete is avoiding the occurrence of explosive spalling at high temperatures. Target temperature of concrete is around 600℃ during fire [6]. The use of Brass coated steel fibre in concrete with GGBS is protective structures against fire and extreme loading conditions (e.g. high-velocity impact and blast), which is attributed to its advantages of higher tensile strength and better energy absorption capability compared to normal concrete. As per cube results it was concluded that the optimum percentage of steel fiber was 8% of total dry material and size 13 mm length used which has recorded the highest compressive strength at 28th days.
