INVESTIGATION AND STUDY OF HIGH PERFORMANCE STEEL FIBER REINFORCED CONCRETE

Concrete structures may be subjected to dynamic loading during their service life. Understanding the dynamic properties of concrete structures is becoming critical because of the increased concern about the dynamic loading of both civilian and military structures. Fiber reinforced concrete (FRC) is known to exhibit superior performance in its post-peak energy absorption capacity, (i.e., toughness) under flexural and tensile loading. However, the behavior of fiber reinforced concrete under compressive impact has not previously been investigated. In the present research, the response of fiber reinforced concrete was investigated over the full strain rate regime, from static loading to high strain rate loading, and finally to impact loading. In the present study the role of using polymer cement concrete is used to increase the flexural strength and compressive strength of concrete. It acts as a bridge over the crack and there by arresting those cracks from widening. It increases the strength without increasing the density of concrete.
