| Abstract: | In this study, nine different types of concrete were adopted: vibrated
traditional concrete (VTC) with low slump (68 mm) and eight types of
self-compacting concrete (SCC) in which cement was partially replaced by four
kinds of replacements (25%, 30%, 35% and 40%) of class F fly ash (FA) and by
four kinds of replacements (5%, 10%, 15% and 20%) of silica fume (SF). The main
objective of this research was to evaluate the effect of different types and
dosages of mineral additions on the mechanical properties and abrasion
resistance of SCC. Compressive, splitting tensile strength and UPV tests were
conducted for the ages of 3, 28 and 130 days whilst the modulus of elasticity
and the abrasion resistance tests were performed for 28 days. Consequently, it
was found that although the compressive and tensile strength and the UPV values
of SCC specimens were higher generally than those of VTC specimens for all
curing ages, the compressive strength and the UPV values of SCC specimens
decreased for 3 days when FA and SF content increased. The modulus of
elasticity of SCC specimens with SF in general increased with an increase in SF
content whilst the modulus of elasticity decreased with an increase in FA
content. Moreover, it was concluded that increasing SF content more improved
the abrasion resistance of SCC compared to FA whilst the abrasion resistance of
all SCC specimens was higher than that of VTC. On the other hand, there was a
strong correlation, which is not dependent on the mineral admixture type and
content, between the wear loss with compressive strength and the elasticity
modulus for SCC specimens. |
