Experimental analysis of time dependent phenomena and temperature effects on macro-synthetic fibre reinforced concretes in different loading conditions
نویسندگان
چکیده
Fibre reinforced concretes (FRCs) are composite materials now largely adopted in structural applications given their mechanical properties terms of the residual tensile strength, almost absent for plain concrete. The short-term behaviour these material has been deeply studied, while time-dependent deformations have received less attention from scientific community. present paper presents experimental characterization creep a concrete with polypropylene fibers by means different types tests, together an analysis temperature effect. Innovative test set-ups used to this aim. results shrinkage, compression creep, uniaxial tension and flexural tests discusses contribution components FRC behavior.

Abstract Concrete is an indisputable material for the construction of various types of structures in the modern advancement of civil infrastructures. Concrete is strong in compression but weak in tension and shear. To eliminate those problems, the introduction of fiber was brought in as an alternative to developing concrete in view of enhancing its tensile and shears strength as well as improvi...
