文摘

Mechanical properties of HSC containing PP, MP and hybrid fibers with nano-silica and silica fume were studied. The optimum percentages of fibers and pozzolans were selected and employed in producing high-strength concrete. Introducing nano-silica and silica fume improved mechanical properties and durability of concrete. Substitution of MP with PP fibers reduced mechanical properties of concrete. High volume fractions of PP fiber brought about negative effects on mechanical properties of HSC.
