Infomesen blong Testing
Test blong konkrit i wan servis blong ol laboratwa blong nid-parti we i checkem ol properti blong konkrit, we i wan mane material we ol man yusum long ol bilding, brig, rod, dam, bunker blong heldem wota, ol foundesen blong haos, ol slab, ol pilar, ol wal, mo ol taem ol man mekem precast element. Test blong konkrit i kavaem checkem ol sample we ol man tekem folem sampla blong wol long saet blong wok, mo tu checkem ol konkrit afta i hed, blong luk se i stap gut o i no stap gut long wok blong konstraksen.
Purpos blong test blong konkrit i blong save se ol properti mechanical mo fisikal blong konkrit, olsem strength long compressen, strength long tensilen, modulus blong elastisiti, workabiliti blong fresh konkrit, durabiliti, mo resistens blong penetraten blong kloraid, i foldaem ol rekirement blong standard design o i no foldaem. Ol teknik we laboratwa i yusum inklud compressen testing long ol cub o silinda, flexural testing long beam, non-destructiv testing olsem rebound hamma mo ultrasonik pulse velociti, kloraid penetrasen test, mo analysis blong ol komponent blong mixtur olsem seman, agregat, wota, mo admikstua.
Tipikal proses blong test i stat long samplen, we ol man kastem cub blong 150 mm o silinda blong 100 mm x 200 mm long saet,Keepem long kiu blong wota 27 ± 2 degre selcius, afta i tekem blong test long 3, 7, 14, o 28 dei blong ej. Long laboratwa, ol teknisian i kapap ol sample, putum long compressen mashin, i apply lod bit by bit, mo i rekordem maximam lod blong brekem. Ol core sampl tu ol man save drilum folem struktur finis blong checkem strength in-place. Ol paramita moa inklud slump, ej blong ej, densiti, absorpsen blong wota, mo depth blong karbonaten.
Test blong konkrit i helpem ol injinia, ol kontraktor, ol Developa, mo ol gavman bodi blong verifyem kwaliti blong material, blong checkem se mix design i foldaem specifikasen, blong dignozem defek olsem heallow hol, krak, o delaminaten long struktur, mo blong mekem decisen long taim blong ripar o asesem kondisen blong wan bilding we i stap long yus finis.
