Fiber ntau - txhawb ntxiv yas (FRP) (tseem hu ua fiber ntau - txhawb ntxiv polymer, lub fiber ntau - txhawb ntxiv yas) yog cov khoom sib xyaw ua los ntawm polymer matrix txhawb ntxiv nrog fibers. Cov fibers feem ntau yog iav (hauv fiberglass), carbon (hauv carbon fiber reinforced polymer), aramid, los yog basalt.

Hauv qhov no, vim li cas Fiber reinforced pob zeb?

Cov nyhuv ntawm fibers hauv pob zeb Fibers feem ntau yog siv rau hauv pob zeb los tswj kev tawg vim cov yas shrinkage thiab kom qhuav shrinkage. Lawv kuj txo cov permeability ntawm pob zeb thiab yog li txo cov ntshav dej. Qee hom fibers ua kom muaj kev cuam tshuam ntau dua-, puas-, thiab tawg-ua haujlwm hauv pob zeb.

Qhov thib ob, puas fiber ntau hloov rebar? Tsis txhob nyob rau hauv ib tug structural slab. Fiber ua TSIS TAU hloov kev txhawb zog !! Nws yog ib qho ntxiv uas pab tswj "qee" ntawm cov kab nrib pleb tshwm sim los ntawm shrinkage!

Ib sab saum toj no, qhov twg Fiber reinforced pob zeb siv?

Qhov ratio ntawm lub fiber ntau yog qhov piv ntawm nws qhov ntev rau nws txoj kab uas hla. Qhov piv txwv zoo sib xws li ntawm 30 txog 150. Fiber ntau - kev txhawb zog yog mas siv nyob rau hauv shotcrete, tab sis kuj yog siv hauv qhov qub pob zeb . Fiber ntau - txhawb ntxiv li qub pob zeb feem ntau yog siv rau hauv pem teb thiab pavements.

Dab tsi yog steel fiber reinforced pob zeb?

Steel Fiber Reinforced Concrete (SFRC) Steel fiber reinforced pob zeb yog cov khoom siv sib xyaw muaj fibers Raws li cov khoom xyaw ntxiv, dispersed uniformly ntawm random nyob rau hauv me me feem pua, piv txwv li ntawm 0.3% thiab 2.5% los ntawm ntim nyob rau hauv dawb pob zeb.
