Rebar, luv luv rau kev txhawb nqa bar, tuaj yeem tawg thaum khoov vim ntau yam ntsig txog nws cov khoom siv, tuav, thiab khoov txheej txheem:
Khoom zoo: Qhov zoo thiab qib ntawm rebar ua lub luag haujlwm tseem ceeb. qis dua -qib rebar lossis rebar nrog impurities tej zaum yuav muaj lub zog tsis sib xws, ua rau nws yooj yim dua rau kev tawg thaum khoov.
Brittleness: Rebar tuaj yeem ua nkig vim kev tuav tsis raug, cia, lossis raug kub heev. Brittle rebar feem ntau yuav tawg los yog tawg thaum raug khoov quab yuam.
Cov txheej txheem khoov tsis raug: Khoov rebar yuav tsum muaj kev txawj ntse thiab siv cov cuab yeej tsim nyog. Yog hais tias lub vojvoog dabtsi yog khoov nruj dhau los yog siv lub zog ntau dhau thaum khoov, nws tuaj yeem tshaj qhov rebar lub zog tawm los, ua rau nws tawg.
Ua ntej-Cov Tsis Zoo uas twb muaj lawm: Txhua yam tsis xws luag hauv rebar, xws li microcracks lossis voids, tuaj yeem ua raws li kev ntxhov siab concentrators thaum khoov. Cov teeb meem no tuaj yeem nthuav tawm thiab ua rau tsis ua tiav tam sim ntawd.
nkees: Rov qab khoov lossis khoov tom qab kev ntxhov siab dhau los (xws li khoov thiab ncaj) tuaj yeem ua rau qaug zog hauv lub rebar. Kev qaug zog ua rau cov khoom tsis muaj zog thaum lub sijhawm thiab tuaj yeem ua rau tsis ua haujlwm thaum lub sijhawm khoov tom ntej.
Corrosion: Yog hais tias rebar yog corroded, nws tus ntoo khaub lig -sectional cheeb tsam thiab lub zog yuav raug txo. Corrosion ua rau cov rebar tsis muaj zog thiab ua rau nws yooj yim rau kev tawg thaum khoov.
Kev tuav tsis raug: Kev siv tsis raug thaum lub sij hawm thauj mus los lossis kev khaws cia tuaj yeem ua rau lub cev puas tsuaj lossis khoov ntawm lub rebar dhau ntawm nws qhov kev txwv tsis pub muaj zog, ua rau nws tsis muaj zog thiab ua rau nws yooj yim rau kev tawg thaum lub sij hawm khoov tom ntej.
