Infomesen blong Testing
ZHONGXI Testing i wok long tesim ol kabel blong concrete, we ol save kolem olsem kabel o pre-stressing tendon we ol man putum insaed long concrete blong mekem strong, mo testing ia i kamaot wan samting we laboratori blong third-party i save givim long ol kampaeni we ol i mekem o yusum ol kabel ia. Kabel blong concrete ol man yusum tumas long ol bridge, ol haes bilding, ol tunnel, ol wharf, ol nuclear power station, mo ol precast concrete elemesem olsem beam, slab, pile, mo sleepa blong reil we ol nid strong tumas mo i no save bruk kwik.
Purpos blong testing blong kabel blong concrete emi blong save serten se strant mo kialiti blong kabel ia i minim ol standard, se i save hole long load we ol disaenem, mo se i no save givim wan problem long STRKTURA blong concrete afta ol installem. Ol teknik we laboratori i yusum oli inkld tensail testing, relaxesen testing, fatig testing, korosion analisis, kemikal komposisen analysis, jeometrikal measmen, mo non-destructive testing blong chek defekt insaed long wia o insaed long strand.
Testing proces blong nomo i stat long sampl preparasen, we ol man tek sampl long batc o long rol wetem ol metod blong random sampling. Afta ia ol man measrem diameda blong evri wia, namba blong wia insaed strand, masa blong coating, mo tensail strent. Ol man putum sampl long universal testing masin, ol aplaem load sloli sloli, mo ol rekodem elongesen, yield point, ultimatem tensail strent, mo modulas blong elastisiti. Long kabel we i gat coating, ol man tesim coating thicknes, adiesen, mo resistens blong coating long salt spray. Long ol kabel we ol installem finis insaed long structura, ol man yusum ol teknik olsem impact echo, ultrasonik, mo magnetic flux leakage blong detektem korosion o brakeij insaed.
Korek parameters we laboratori i evriuem oli inkld ultimatem tensail strent we ol expres long MPa, yield strent, elongesen afta brek, reduksen blong area, relaxesen afte 1000 aoa, fatig liftaim, resistens blong korosion, bend test, mo reverse bend test. Evri parameter i gat impotens blong hem: tensail strent i sehem se kabel save hole load blong pre-stressing; relaxesen i soem hamas fors i lusum ova taim; korosion testing i soem hamas yia kabel save las long environmen we i gat salt o moista.
concrete kabel testing Ol Testing Instrument

- Ol reton kabel mo repair kabel we ZHONGXI Testing i evriuem long existing structura blong assesssem kondisen afta long servis.
Summary
Testing blong concrete kabel i kavarem tensail strent, yield strent, elongesen, modulas, relaxesen, fatig, kemikal komposisen, coating propati, anchorej efisiensi, grout kialiti, mo non-destructive inspeksen blong kable insaed servis. Skop i kavarem ol kable tip olsem 7-wia strand, single wia, epoxy coated, galvanized, unbonded, bonded, CFRP, stay cable, mo ground anchor. Turnaround i stat long 7 woking dei blong basic testing mo i go kasem 15 dei o mo longtaem blong ful evaluwesen we i inkludem long-term item olsem relaxesen mo fatig.
