The effects of 20%, 30% and 40% fly ash on the properties of fibre reinforced cementitious composites were studied. The results showed that the fresh slurry changed from shear thinning to shear thickening with the increase of fly ash content. The flexural strength of specimens increased slightly, but the compressive strength of specimens decreased with the increase of fly ash amount. Moreover, the flexural strength of all specimens showed different degrees of shrinkage over time. With the increase of the content of fly ash, the elastic modulus of specimens decreased.
