Abstract:
The elastic moduli of fiber reinforced concrete were solved by using theory of meso-mechanics based on Mori-Tanaka and Eshelby equivalent inhomogeneous method. Some parameters influencing elastic moduli of fiber reinforced concrete were discussed, and the elastic moduli of fiber reinforced concrete were given as a function of physical properties and volume fraction of the following four components: sand, gravel, fibers and cement as matrix. Finally, a comparison was also made between theoretical solutions and published experimental data, and two aspects were in good agreement. It is validated that it is a possible and effective method for solving elastic moduli of fiber reinforced concrete by using theory of meso-mechanics.
