Abstract

The need of high performance concrete HPC is increasing in the recent years. This material becomes necessary, but it is brittle. So, fibers are used to enhance mechanical properties of HPC. The enhanced properties include tensile strength, compressive strength, elastic modulus, crack resistance, crack control, durability, fatigue life, resistance to impact and abrasion, shrinkage, expansion, thermal characteristic, and fire resistance of concrete. The main objective of this research is to study the effect of using Harex, polypropylene and glass fibers on flexural behavior of High performance concrete beams under static and repeated loads.
