Abstract: Abstract: An experimental program was carried out to evaluate the
mechanical properties of cement-based composites. Test variables
included water to cementitious ratio, dosage of silica fume
and volume fraction of steel fiber. Compressive strength test,
direct tensile strength test, splitting tensile strength test, abrasion
resistance test and drop weight test were performed and the
results were analyzed statistically. According to the results of
this study, the designed direct tensile testing method was a
suitable method to estimate the tensile strength of fiber cement-based
composites. Addition of fibers provided better
performance for the cement-based composites, while silica
fume in the composites would help obtaining uniform fiber
dispersion in the matrix and improve strength and the bonding
between fiber and matrix resulting from extra dense calcium-silicate-hydrate
gel. The combination of steel fibers and
silica fume can greatly increase the mechanical properties of
cement-based composites. Besides, a multiple regression analysis
was conducted to correlate compressive strength, direct
tensile strength, abrasion coefficient and impact number with
w/cm ratio, silica fume content and steel fiber content and a
fairly agreement between test data and estimated values was
found.
