Compressive behavior of steel fiber reinforced recycled coarse aggregate concrete designed with equivalent cubic compressive strength
https://orcid.org/0000-0003-1074-5631
HighlightsSpecimens with 0–100% RCA replacement ratio and nearly equivalent cubic compressive strength were considered.Combined effect of SFs and RCA on compressive behavior of SFRCAC was studied.An empirical formula for Young’s modulus and strain as well as a constitutive model of SFRCAC were proposed.Crack patterns of SFRCAC were found to be different depending on fiber volume.
AbstractThis paper presents the experimental results related with the compressive behavior of steel fiber reinforced-recycled coarse aggregate concrete (SFRCAC). Compressive strength, Young’s modulus and stress-strain curves were carried out on more than 100 specimens. Emphasis was placed on the combined effect of steel fibers (SFs) and recycled coarse aggregate (RCA) on the axial compressive behavior of SFRCAC with equivalent compressive strength. Test results indicate that with the addition of SFs, Young’s modulus and stress-strain curves of SFRCAC are similar to those with natural coarse aggregate (NCA) concrete, but the critical strain has a significant increase with the increase of steel fiber content and RCA replacement ratio. Regression formula of compressive strength, Young’s modulus, critical strain and constitutive model of SFRCAC are proposed.
