Cov hlau hlau uas tau ua kom nruj yog ib qho khoom siv tau ntau yam thiab tseem ceeb hauv kev lag luam kev tsim kho. Ua los ntawm cov hlau zoo uas muaj cov pa roj carbon ntau uas tau kho cua sov thiab ua haujlwm txias, cov hlau no tau tsim tshwj xeeb los ua kom tau raws li qhov xav tau ntawm kev txhawb nqa pob zeb ua ntej. Cov hlau hlau muaj cov pa roj carbon ntawm 0.65% txog 0.85%, cov pa sulfur thiab phosphorus tsawg dua 0.035%, thiab muaj lub zog zoo heev thiab ruaj khov.
Txij li thaum xyoo 1920s, cov hlau ua los ntawm cov hlau prestressed tau ua tiav zoo heev. Niaj hnub no, ntau yam khoom tsim nyog rau ntau yam kev siv thiab nrog cov yam ntxwv sib txawv tau tsim. Cov no suav nrog cov hlau txias rub, cov hlau ncaj, cov hlau so kom tsawg, cov hlau galvanized thiab cov hlau qhab nia. Cov khoom no, ua ke nrog cov hlau prestressed, tau dhau los ua cov hlau prestressed uas siv dav tshaj plaws hauv ntiaj teb.
Hais txog kev faib tawm, cov hlau PC uas tsis muaj zog yog qhov kev xaiv nrov. Nws lub zog tensile zoo heev ua rau nws zoo tagnrho rau cov ntawv thov kev ntxhov siab siab. Tsis tas li ntawd, qhov tuab ntawm cov hlau hlau yog 2.64 hli, ua rau nws haum rau ntau yam haujlwm tsim kho. Tsis tas li ntawd, cov hlau prestressed concrete no ua raws li cov qauv teev tseg hauv 1084 SAEJ403, ua kom ntseeg tau tias nws zoo thiab ntseeg tau.
Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm cov hlau prestressed yog nws lub zog tensile tshwj xeeb. Feem ntau, lub zog tensile ntawm hom hlau no yog siab dua 1470MPa, maj mam hloov mus rau qib zog tseem ceeb ntawm 1670 ~ 1860MPa. Ntxiv mus, txoj kab uas hla ntawm cov hlau kuj tau hloov pauv mus rau lub sijhawm, los ntawm 3 txog 5 hli mus rau qhov tam sim no ntawm 5 txog 7 hli. Qhov zog ntxiv no thiab txoj kab uas hla loj dua ua rau cov hlau prestressed muaj zog heev thiab muaj peev xwm tiv taus cov khoom loj.
Vim nws cov khoom zoo heev, cov hlau prestressed siv dav hauv ntau qhov chaw tsim kho. Nws feem ntau siv los txhawb cov qauv xws li choj, tsev thiab txoj kev tsheb ciav hlau kom txhim kho lawv lub peev xwm thauj khoom thiab kev ua tiav ntawm cov qauv. Cov kev lag luam thiab cov chaw tsim kho vaj tse vam khom ntau rau cov hlau prestressed kom ntseeg tau tias lawv cov haujlwm siv tau ntev thiab muaj kev nyab xeeb.
Hauv kev xaus lus, kev tsim cov hlau prestressed tau hloov pauv kev lag luam kev tsim kho. Kev sib xyaw ua ke ntawm cov hlau zoo carbon thiab cov txheej txheem machining siab heev ua rau muaj ntau yam khoom tsim nyog rau ntau yam kev siv. Nrog ntau yam kev faib tawm thiab kev xaiv qhov loj me, nrog rau lub zog tensile zoo heev thiab ntau yam kev siv, hlau prestressed tseem yog ib qho tseem ceeb hauv kev tsim kho niaj hnub.
