Basic creep under compression and direct tension loads of self-compacting-steel fibers reinforced concrete

Abstract

Most previous research carried out in self-compacting steel fiber reinforced concrete (SCSFRC) have focused on the short-term mechanical properties, with few works dedicated to its creep behavior. Moreover, the study of creep plays an important role for the evaluation of the long-term service-state of concrete structures. In this work, it is presented an experimental investigation that includes tensile and compressive creep tests on SCSFRC. The self-compacting mixes were reinforced with volume fractions of 0%, 1% and 1.25% of steel fibers (35 mm and 65 mm). The results indicated that tensile creep is smaller than compressive creep and that fibers do not significantly change compressive creep. © RILEM 2012.
