Cov Khoom Tshiab Kub Macro Fiber Rau Cov Haujlwm Hydropower - Macro Synthetic Fiber Reinforced Concrete – Kehui

Cov pob zeb ua vaj tse yog ib yam khoom uas muaj zog nias siab tab sis lub zog tensile tsawg dua li kaum npaug. Ntxiv mus, nws yog tus cwj pwm los ntawm tus cwj pwm brittle thiab tsis pub hloov kev ntxhov siab tom qab tawg. Yuav kom tsis txhob muaj kev puas tsuaj brittle thiab txhim kho cov khoom siv kho tshuab, nws muaj peev xwm ntxiv cov fibers rau hauv cov pob zeb sib xyaw. Qhov no tsim cov fiber reinforced concrete (FRC) uas yog cov khoom sib xyaw cementitious nrog cov khoom siv reinforcement dispersed hauv daim ntawv ntawm cov fibers, piv txwv li hlau, polymer, polypropylene, iav, carbon, thiab lwm yam.
Cov fiber reinforced concrete yog cov khoom siv sib xyaw ua ke nrog cov cementitious uas muaj cov fibers dispersed. Polypropylene fibers tuaj yeem muab faib ua microfibers thiab macrofibers nyob ntawm lawv qhov ntev thiab lub luag haujlwm uas lawv ua hauv cov concrete.
Cov macro synthetic fibers feem ntau yog siv rau hauv cov qauv pob zeb ua ib qho kev hloov pauv rau cov hlau nominal lossis cov ntaub txhawb nqa; lawv tsis hloov cov hlau qauv tab sis cov macro synthetic fibers tuaj yeem siv los muab cov pob zeb nrog lub peev xwm tom qab tawg.

Cov txiaj ntsig:
Kev txhawb zog sib dua;
Kev tswj hwm qhov tawg zoo heev;
Kev ruaj khov zoo dua;
Muaj peev xwm tom qab tawg.
Yooj yim ntxiv rau cov pob zeb sib xyaw txhua lub sijhawm
Cov ntawv thov
Cov phiaj xwm ua los ntawm cov pob zeb shotcrete, xws li cov hauv paus, txoj kev, cov choj, cov chaw tsuas, thiab cov phiaj xwm txuag dej.
