Igishushanyo mbonera cya kawa ya silindrike
GRC ni iki?
GFRC isa na fiberglass yaciwe (ubwoko bwakoreshejwe mugukora ubwato hamwe nubundi buryo bugoye butatu), nubwo ari intege nke cyane.Ikozwe muguhuza uruvange rwumucanga mwiza, sima, polymer (mubisanzwe polymer acrylic), amazi, izindi mvange hamwe na fibre yibirahure irwanya alkali (AR).Ibishushanyo byinshi bivanga biboneka kumurongo, ariko uzasanga byose bisangiye ibisa nibintu bikoreshwa.
Zimwe mu nyungu nyinshi za GFRC zirimo:
Ubushobozi bwo kubaka panne yoroheje
Nubwo ubucucike bugereranije busa na beto, paneli ya GFRC irashobora kuba yoroheje cyane kuruta imbaho gakondo, bigatuma yoroshye.
Imbaraga Zikomeye, Zoroshye kandi Zifite imbaraga
Igipimo kinini cya fibre yibirahure kiganisha ku mbaraga zikomeye mugihe ibintu byinshi bya polymer bituma beto ihinduka kandi ikarwanya gucika.Gushimangira neza ukoresheje scrim bizarushaho kongera imbaraga zibintu kandi nibyingenzi mumishinga aho ibice bigaragara bitihanganirwa.
Fibre muri GFRC- Uburyo Bakora
Fibre yibirahuri ikoreshwa muri GFRC ifasha gutanga iyi compound idasanzwe imbaraga zayo.Alkali irwanya fibre ikora nkihame ryumutwaro uremereye utwara umunyamuryango mugihe polymer na matrix ya beto ihuza fibre hamwe kandi igafasha kwimura imizigo ivuye mumibiri iyindi.Hatariho fibre GFRC ntabwo yaba ifite imbaraga zayo kandi yakunda gucika no gucika.
Gutera GFRC
Ubucuruzi GFRC isanzwe ikoresha uburyo bubiri butandukanye bwo gutera GFRC: gutera hejuru na premix.Reka turebe vuba kuri kimwe kimwe nuburyo buhenze bwo kuvanga uburyo.
Gutera hejuru
Igikorwa cyo gusaba kuri Spray-up GFRC irasa cyane na shortcrete kubera ko ivangwa rya beto y'amazi ivanze muburyo.Inzira ikoresha imbunda yihariye ya spray kugirango ikoreshe ivangwa rya beto ya fluid no gukata no gutera fibre ndende yikirahure kuva kumyanya ikomeza icyarimwe.Spray-up ikora GFRC ikomeye cyane kubera imitwaro myinshi ya fibre nuburebure bwa fibre ndende, ariko kugura ibikoresho birashobora kuba bihenze cyane ($ 20.000 cyangwa arenga).
Ijambo ryibanze
Premix ivanga fibre ngufi mumazi ya beto ivanze hanyuma igasukwa mubibumbano cyangwa bigaterwa.Koresha imbunda ya premix ntabwo ikenera fibre, ariko irashobora kubahenze cyane.Premix nayo ikunda kugira imbaraga nke ugereranije no gutera hejuru kuva fibre kandi ngufi kandi igashyirwa muburyo butemewe mugihe cyose.
Hybrid
Uburyo bumwe bwa nyuma bwo gukora GFRC ni ugukoresha uburyo bwa Hybrid bukoresha imbunda ya hopper ihendutse kugirango ushireho ikote ryo mumaso hamwe nintoki cyangwa isuka ivanze ninyuma.Isura yoroheje (idafite fibre) iterwa mubibumbano hanyuma kuvanga inyuma bigapakirwa mukiganza cyangwa bigasukwa cyane nka beto isanzwe.Nuburyo buhendutse bwo gutangira, ariko nibyingenzi kurema neza witonze byombi bivanga mumaso hamwe nuruvange rwinyuma kugirango tumenye guhuza no kwisiga.Ubu ni bwo buryo abakora ibintu byinshi bifatika bakoresha.
