Concrete is one of the most widely used materials in the construction industry, so in recent years, the approach of construction industry experts has been focused on improving the quality of this product. One of the technical characteristics of concrete that has been considered by researchers in research is its compressive and tensile strength. To achieve this goal, in recent years, the use of less water to cement ratio with the help of superplasticizers, as well as the use of natural or synthetic pozzolans, as well as the use of fibers of different materials and specifications, in Concrete composition is common. Identifying the properties of concrete as one of the most widely used building materials has always been studied by many researchers. Compressive strength of concrete has been one of the characteristics that many experts have studied. Due to the current popularity of airport runways and helicopter pads, the need for final concrete coatings with the ability to accept heavy flights and wide-body aircraft using materials that have acceptable compressive and tensile strength has increased, in this way The use of composite concretes can be one way to meet this need. Our aim in this study is to investigate the effects of adding fibers of different materials on the strength properties of concrete.
