Cov hlau hlau ua los ntawm cov pob zeb ua ntej muaj zog, tseem hu ua cov hlau carbon siab, yog cov khoom siv hauv tsev uas siv dav thiab txhim khu kev qha uas ua tau raws li qhov yuav tsum tau ua rau cov qauv pob zeb ua ntej muaj zog. Cov hlau no yog ua los ntawm cov hlau kub-kub zoo, uas tau kho cua sov thiab ua haujlwm txias kom ntseeg tau tias nws zoo thiab ua tau zoo. Cov hlau no muaj cov pa roj carbon ntawm 0.65% txog 0.85%, cov pa sulfur thiab phosphorus tsawg dua 0.035%, thiab yog tsim los ntawm cov qauv kev lag luam siab tshaj plaws.
Txij li thaum xyoo 1920s, cov hlau ua los ntawm cov hlau prestressed tau muaj ntau xyoo ntawm kev txhim kho thiab kev txhim kho. Niaj hnub no, ntau yam khoom sib txawv tau tsim los ua kom tau raws li ntau yam kev xav tau ntawm kev tsim kho. Cov no suav nrog cov hlau txias, cov hlau ncaj, cov hlau so kom tsawg, cov hlau galvanized thiab cov hlau scored. Cov khoom sib txawv no, thaum siv rau hauv kev tsim cov hlau prestressed, tau dhau los ua cov hlau prestressed uas siv ntau tshaj plaws hauv ntiaj teb.
Lub zog tensile ntawm cov hlau ua los ntawm cov pob zeb prestressed feem ntau yog siab dua 1470MPa, thiab nws qib zog tau hloov pauv los ntawm feem ntau 1470MPa thiab 1570MPa mus rau feem ntau 1670 ~ 1860MPa. Lub cheeb ntawm cov hlau kuj tau hloov pauv, los ntawm 3-5 hli mus rau 5-7 hli. Qhov nce ntawm lub zog thiab lub cheeb ua kom muaj kev ruaj khov thiab kev ntseeg tau ntawm cov qauv pob zeb reinforced.
Cov xov hlau ua los ntawm cov pob zeb ua ntej siv dav hauv kev lag luam kev tsim kho. Nws lub zog tensile siab thiab ruaj khov ua rau nws zoo tagnrho rau kev txhawb nqa ntau yam qauv pob zeb xws li choj, tsev thiab txoj kev loj. Nws ua kom cov pob zeb tsis txhob tawg, txo cov kab nrib pleb thiab txhim kho lub peev xwm thauj khoom. Tsis tas li ntawd, nws qhov kev hloov pauv tau yooj yim ua rau nws yooj yim hloov kho kom tau raws li cov kev xav tau tshwj xeeb ntawm kev tsim kho.
Hauv kev xaus lus, cov hlau ua los ntawm cov pob zeb prestressed yog cov khoom siv hauv tsev zoo uas tuaj yeem muab kev txhawb nqa zoo rau cov qauv pob zeb prestressed. Nws cov khoom lag luam thiab cov yam ntxwv ua kom txhua yam kev xav tau ntawm kev tsim kho tau ua tiav. Nrog nws lub zog zoo dua, kev ruaj khov thiab kev hloov pauv tau yooj yim, nws tau dhau los ua qhov kev xaiv zoo tshaj plaws hauv kev lag luam kev tsim kho thoob ntiaj teb. Txawm hais tias siv rau hauv cov choj, cov tsev lossis txoj kev loj, cov hlau ua los ntawm cov pob zeb prestressed lav qhov kev ua kom zoo dua qub thiab lub neej ntev.
