Investigating the Impact Resistance in RSNN Reactive Powder Concretes and Ordinary NSRN Concretes


Navid Mohammadnia, Hadi Mahdizad Nami
Abstract

Nowadays, the progress in the construction industry has seemingly made it necessary to use new and substitute materials. One of the materials used in concrete industry during the recent decade is the reactive powder concrete. The present study deals with the impact strength of this concrete considering the remarkable strength properties of this concrete. The samples included concrete beams with 120×120×120cm dimensions and their reactions to the free fall of a weight from a fixed elevation provide information that can be used as a good basis for comparing the concretes’ impact performance. In order to measure and compare the behavior of the beams, use has been made of image processing software. The experimental samples include reactive powder concrete specimens with steel fiber without strengthening armature and FRP coating (RSNN) and the ordinary concrete specimens with steel fiber as well as shear armature and without FRP coating (NSRN).
