The properties and application of composite materials on the example of concretes with the addition of steel and synthetic fibers

Abstract

The properties of fiber-reinforced concretes are currently the subject of many studies due to the possibility of using that type of material in various fields of building engineering. The fiber- reinforced concretes are composite materials, that consist of a concrete matrix and fibers. There are applied many kinds of fibers, for example made of steel, polypropylene or glass. The addition of fibers to the concrete has a beneficial effect on many of its features, including increased impact strength, reduced shrinkage and it also improves concrete strength. The paper presents the possibilities of using reinforced concretes with the addition of steel and propylene fibers.
