In　order　to　master　the　mechanical　troughness　the　alkali-resistant　bundling　glass-fiber　reinforced　concrete,　the　axial　tensile,　four-point　bending　toughness　and　three-point　incision　beam　fracture　tests　were　carried　out,　respectively,　on　the　alkali-resistant　bundling　glass-fiber　reinforced　concrete.　The　steel　fiber　concrete　and　the　crude　polyolefin　fiber　concrete　had　volume　fractions　of　0.45%　and　0.75%,　respectively.　The　influence　of　fiber　fraction　on　the　mechanical　properties　of　the　alkali-resistant　bundling　glass-fiber　reinforced　concrete　was　analyzed　and　compared　with　the　steel　fiber　concrete　and　crude　polyolefin　fiber　concrete　with　the　same　volume　fraction.　Test　results　show　that　the　axial　tensile　properties　of　the　alkali-resistant　bundling　glass-fiber　reinforced　concrete　is　better　than　that　of　crude　polyolefin　fiber　concrete　with　the　same　volume　fraction;　meanwhile,　the　tensile　strength　and　ultimate　tensile　strain　are　slightly　higher　than　that　of　the　steel-fiber　reinforced　concrete　with　the　same　volume.　When　the　alkali-resistant　bundling　glass　fiber　volume　fraction　is　0.75%,　the　flexural　toughness　value　and　peak　intensity　are　191.73%　and　11.47%　higher　than　that　of　plain　concrete,　respectively,　and　the　fracture　toughness　and　fracture　energy　are　28.16%　and　268.69%　higher　than　that　of　plain　concrete,　respectively.　The　flexural　toughness　and　fracture　mechanics　index　of　the　alkali-resistant　bundling　glass-fiber　reinforced　concrete　has　increased　greatly　with　this　volume　fraction.　©　2019,　Editorial　Department　of　Journal　of　HEU.　All　right　reserved.
