Durability Characterisation of Glass Fibre Reinforced Concrete by Resistance to Freezing and Thawing
Keywords:glass fiber reinforced concrete, ductility, static fatigue, freeze/ thaw
Resistance to freezing and thawing of glass fibre reinforced concrete (GRC) modified with silica fume and metakaolin was tested according to scaling at freezing test method with de-icing salt after 112 cycles. Surface mass loss was obtained, flexural strain energies calculated from load- deformation curves and ductile/ brittle behavior of GRC composite explained. SEM micrograph analysis was used to identify possible flaws on the surface of filaments and fiber-matrix contact zone due to freeze-thaw influence.
