Abstract

Impact resistance of concrete is considered as one of the most important properties, needed in the design of concrete units subjected to dynamic loading. Therefore continuous studies and researches are still carried out to determine the best technical and economical design for structures under dynamic loading. This paper takes share in this field aiming to study the effect of different types of fibrous concrete on its impact resistance. Also, This studies was planned to find the most economical fibre and its optimum ratio in concrete mix to get the best results of impact resistance of concrete beams which may exposed to flexural impact loading. 
Unfortunately, there is no standard method to determine the impact resistance of concrete. Thus, an impact apparatus which constructed specially for this research was used to apply strongly the impact load (freely falling weight) at midpoint of beam's span. 
Experimental investigation were carried out on different types of beams (70x10x10 cm.) to determine its impact resistance. Standard cubes were used to determir; the compressive strength of the same mixes of concrete under studies. 
The experimental investigation, carried out in this research, had been planned to find the impact resistance of concrete made from local materials which are commonly used, including different types of fibres such as HAREX, FIBERGLASS and FLAX monofilaments. 
This research realized valuable results showing the effect of the type of concrete on its impact resistance. Also, it cleared the great benefit of using fibrous concrete in increasing impact resistance.
