Structural Behaviour of Steel Fibre Reinforced Concrete Using Flyash
Abstract
The use of steel fibers and fly ash in concrete is increasingly becoming implemented in design codes.Fibres are known
to have an influence on the cracking process and thereby on the material toughness. However when fibers are used in beams,
which include a relatively small amount of conventional flexural reinforcement, their effect can be localized in a limited part of
the concrete. Such localization may lead to a reduction of ductility rather than to its increase, as observed in a previous study of
high strength concrete beams, with and without fibers. This paper presents structural tests with normal strength fiber reinforced
concrete by using 8% fly ash with reinforcement ratios that varied between0% to 7.50%. The results show the effects of adding
fibre sand fly ash on the compression strength of the cube.
