Macro Synthetic Fiber Reinforced Concrete

Qhob yog cov khoom siv ntawm lub siab compressive tab sis nyob ib ncig ntawm kaum zaus me dua tensile lub zog. Tsis tas li ntawd, nws yog tus cwj pwm los ntawm tus cwj pwm nkig thiab tsis tso cai rau kev hloov kev ntxhov siab tom qab tawg. Txhawm rau kom tsis txhob nkig tsis ua haujlwm thiab txhim kho cov khoom siv kho tshuab, nws muaj peev xwm ntxiv fibers rau cov pob zeb sib tov. Qhov no tsim fiber ntau reinforced pob zeb (FRC) uas yog cov cementitious composite khoom nrog ib tug dispersed reinforcement nyob rau hauv ib daim ntawv ntawm fibers, xws li steel, polymer, polypropylene, iav, carbon, thiab lwm yam.
Fiber reinforced pob zeb yog cov khoom siv cementitious sib xyaw nrog cov khoom siv sib cais hauv cov fibers. Polypropylene fibers tuaj yeem muab faib ua microfibers thiab macrofibers nyob ntawm lawv qhov ntev thiab kev ua haujlwm uas lawv ua hauv pob zeb.
Macro hluavtaws fibers feem ntau yog siv nyob rau hauv cov qauv pob zeb ua ib qho kev hloov rau nominal bar los yog ntaub reinforcement; lawv tsis hloov cov qauv hlau tab sis macro hluavtaws fibers tuaj yeem siv los muab cov pob zeb ua kom muaj peev xwm tseem ceeb tom qab tawg.

Cov txiaj ntsig:
Lub zog hnyav;
Superior tawg tswj;
Txhim kho durability;
Tom qab tawg muaj peev xwm.
Yooj yim ntxiv rau kev sib xyaw ua ke txhua lub sijhawm
Daim ntawv thov
Shotcrete, pob zeb ua tej yaam num, xws li lub hauv paus, pavements, txuas hniav, mines, thiab dej txuag tej yaam num.
