Strength and Fracture Toughness of Cement Concrete, Dispersedly Reinforced by Combination of Polypropylene Fibers of Two Types
Abstract The results of the study of the impact of the reinforcement of cement concrete with polypropylene fiber of various types on the strength and crack-resistance characteristics are presented in the article. Consumption of the polypropylene fiber of two types (ordinary and deformed) was taken as the factors. The methods and criteria of fracture mechanics, which are based on the fracture toughness and fracture energy, allowed to carry out a quantitative and qualitative assessment of the effectiveness of addition of two types of polypropylene fiber. The optimum ratio of contents of two types of polypropylene fibers is determined, at which the maximum values of strength and crack resistance of concrete are reached.
