The objective of this book is to provide an experimental investigation on the properties of fiber reinforced concrete consist of natural fibres like coconut coir and also steel fibres were used for comparison in both Normal Strength Concrete (NSC) and High Strength Concrete (HSC).This investigation was carried out using several tests, which included workability test, compressive strength test, indirect tensile strength test, flexural strength test. A total of ten mix batches of normal strength concrete and high strength concrete containing 0%, 0.5% and 1.0% fibre volume dosage rate on coir...
