Steel Fiber Concrete with the Use of Local Production Waste for Transport Facilities

Advances in the field of manufacturing building materials in recent years have made it possible to create a number of new composite materials, the level of properties of which is incomparably higher than the level of properties of traditional concrete. Such materials include steel fiber slag concrete, which includes not only steel fiber, which creates a strong frame, but also metallurgy waste, such as slag, screenings from its crushing, slag sand, etc. The use of these wastes helps to reduce the negative impact on the environment and the cost of work. The analysis of the properties of steel-fiber concrete with the use of waste from local industries for the possibility of using this material in the construction and repair of strategic transport facilities was carried out. It is shown that the use of fiber in concrete increases the moment of crack formation by 10% and significantly reduces the opening of visible cracks. The percentage of fiber by volume in the matrix should not exceed 1.5%.
