INFLUENCE OF INCORPORATION OF JUTE FIBRE AND FERROCHROME SLAG ON PROPERTIES OF CONCRETE

ABSTRACT The present experimental study tries to examine the impact of ferrochrome slag usage as a substitution of coarse aggregates and jute fibre (JF) on different characteristics of concrete. For this, 12 numbers of concrete mixes have been fabricated by introducing 0%, 50% and 100% ferrochrome slag aggregates (FSA) in place of natural coarse aggregates (NCA) and adding 0%, 0.1%, 0.2% and 0.3% JF in concrete. The workability, 7, 28, and 90 days compressive strength (CS), flexural strength (FS), split tensile strength (STS), ultrasonic pulse velocity (UPV), rebound number (RN), water absorption (WA), volume of voids (VV), density of designated mixes, have been studied to access the effect of incorporation of FSA and JF in concrete. The experimental outcome analysis depicts the concrete mix having 50%–100% FSA and 0.1% JF has strength, physical and non-destructive parameters similar to those of normal concrete. Furthermore, 50%–100% FSA usage has been recommended as a substitution of coarse aggregates because the incorporation of FSA has no substantial impact on various concrete properties. It is also detected that 0.1% JF could be introduced in concrete without significant degradation of concrete behaviour since, beyond this level, the properties of concrete are adversely affected.
