【 摘 要 】

We observed causes of using fiber in nowadays construction industry and its influence on a final product properties, where the fine-grained concrete basing of repairing dry construction mix was used as a base. However, in Russia we do not have such experience. If we're talking about changes occurring in the fine-grained concrete all of its are known about it, either in concrete, but in dry-construction mixes changes may have another purpose. Advantages and disadvantages of using fiber were oblieved also in that article. The main subject of this research is the influence of fiber on a mechanical properties of fine-grained concrete. The most attention is paid to estimate the influence of a concrete's properties by metal fibers: casting time (initial and final), workability and strength (tensile strength and compressive strength) in this article. The most popular different type of metal fiber compares for its length and width and the optimum quantity of metal component chooses, which will indicate the maximum possible affirmative result of its using. Dependences comparing properties of fine-grained properties with fiber's type, measurements and quantity which show the evident result of researching are discussed.
