Experimental Study Of The Mechanical Properties Of Fiber Reinforced Concrete And Finite Element Analysis

This paper analyzes the performance of less than ordinary concrete and fiber reinforced concrete on the basis of performance characteristics, at low temperatures for the steel fiber reinforced concrete, polyacrylonitrile fiber reinforced concrete, and new ways (steel-PAN hybrid fiber reinforced concrete) for a certain the study. This paper focuses on the mechanical properties of fiber reinforced concrete to do the following:1 prepared according to principles of fiber reinforced concrete material properties and composition were prepared by plain concrete, steel fiber reinforced concrete, polypropylene fiber reinforced concrete eyes, steel-polypropylene fiber reinforced concrete eyes.2 mechanism with the analysis of fiber-reinforced fiber reinforcement, concrete damage by studying the impact of various factors, an analysis of its failure mechanism.3 at low temperature (0℃) for four different volume fractions of steel fiber reinforced concrete, polypropylene fiber reinforced concrete eyes, steel-eyes polypropylene fiber concrete compressive and flexural mechanical properties of the comparison test, analysis of the various fiber concrete characteristics, obtained various parameters of the mechanical properties of fiber reinforced concrete.4 at room temperature to study the plain concrete and V=1.5% of the hybrid fiber reinforced concrete cube compression cyclic loading test. Studied the cyclic loading effect on the bonding of two materials, as well as weakening the ultimate bearing capacity.5 obtained in the test parameters, based on the finite element analysis, and the whole style with layered ash are two ways to V=1.5% of the hybrid fiber reinforced concrete used in road pavement engineering, and under the static vehicle general plain concrete pavement concrete materials the mechanical properties were compared.Test results and finite element analysis showed that fiber reinforced concrete has excellent mechanical properties, obtained results for the fiber reinforced concrete in the practical application of engineering to provide a reference.
