Tšusumetso ea khalase ea fiberglass ho hanyetsa khoholeho ea konkreite e nchafalitsoeng (e entsoeng ka likaroloana tsa konkreite tse nchafalitsoeng) ke sehlooho se khahlang haholo mahlale a thepa le boenjiniere ba sechaba. Le hoja konkreite e tsosolositsoeng e fana ka melemo ea tikoloho le ea ho tsosolosa lisebelisoa, thepa ea eona ea mochine le ho tšoarella (mohlala, ho hanyetsa khoholeho) hangata li tlaase ho konkreite e tloaelehileng. Fiberglass, joalo kathepa e matlafatsang, e ka ntlafatsa ts'ebetso ea konkreite e nchafalitsoeng ka mekhoa ea 'mele le ea lik'hemik'hale. Mona ke tlhahlobo e felletseng:
1. Thepa le Mesebetsi eaFiberglass
Fiberglass, sesebelisoa sa inorganic non-metallic, se bonts'a litšobotsi tse latelang:
Matla a phahameng a tensile: E lefella matla a tlase a konkreite.
Corrosion resistance: E hanela tlhaselo ea lik'hemik'hale (mohlala, li-ion tsa chloride, sulfate).
Ho toughening and crack resistance**: E koala li-microcracks ho liehisa ho ata le ho fokotsa ho kenella.
2. Durability Mefokolo ea Recycled Concrete
Li-aggregates tse entsoeng hape tse nang le pente e salang ea samente holim'a tsona li lebisa ho:
Weak Interfacial Transition Zone (ITZ): Kamano e seng ntle pakeng tsa likarolo tse recycled le peista ea samente e ncha, 'me ho theha litsela tse ka kenang.
Ho se kenelle hantle: Lintho tse senyang (mohlala, Cl⁻, SO₄²⁻) li kenella habonolo, li baka kutu kapa ho senya ho hoholo.
Khanyetso e mpe ea ho qhibiliha: Ho atolosoa ha leqhoa ka har'a li-pores ho baka ho phatloha le ho phatloha.
3. Mekhoa ea Fiberglass ho Ntlafatsa Khanyetso ea Khoholeho
(1) Liphello Tse Thibelang ’Meleng
Crack inhibition: Likhoele tse qhalakaneng ka mokhoa o tšoanang li koala li-microcracks, li thibela kholo ea tsona le ho fokotsa litsela tsa lintho tse senyang.
Motsoako o matlafalitsoeng: Lithapo li tlatsa masoba, li theola porosity le ho liehisa ho hasana ha lintho tse kotsi.
(2) Ho tsitsa ha Lik'hemik'hale
Khalase ea fiber e hananang le alkali(mohlala, AR-glass): Likhoele tse entsoeng ka holim'a metsi li lula li tsitsitse libakeng tse phahameng tsa alkali, li qoba ho senyeha.
Matlafatso ea sefahleho: Khokahano e matla ea fiber-matrix e fokotsa bofokoli ho ITZ, e fokotsa likotsi tsa khoholeho ea lehae.
(3) Ho hanyetsa Mefuta e Khethehileng ea Khoholeho
Khanyetso ea ion ea chloride: Ho fokotseha ha sekhahla ho fokotsa ho kenella ha Cl⁻, ho liehisa ho bola ha tšepe.
Khanyetso ea tlhaselo ea sulfate: Khōlo e hatelletsoeng ea crack e fokotsa tšenyo e tsoang ho crystallization ea sulfate le katoloso.
Ho tšoarella ha leqhoa: Fiber flexible e monya khatello ea maikutlo ho thehoa ha leqhoa, ho fokotsa ho phatloha ha holim'a metsi.
4. Lintlha Tse ka Sehloohong Tse Susumetsang
Tekanyo ea fiber: Lebelo le nepahetseng ke 0.5% -2% (ka molumo); likhoele tse feteletseng li baka ho kopana le ho fokotsa ho kopana.
Bolelele ba fiber le ho hasana: likhoele tse telele (12-24 mm) li ntlafatsa ho thatafala empa li hloka kabo e tšoanang.
Boleng ba li-aggregate tse sebelisoang hape: Ho monya metsi a mangata kapa seretse se setseng se fokolisa maqhama a fiber-matrix.
5. Liphuputso tsa Lipatlisiso le Liqeto tse Sebetsang
Liphello tse ntle: Liphuputso tse ngata li bontša hore ho loketsefiberglassHo phaella moo ho ntlafatsa haholo ho se lekane, ho hanyetsa chloride, le ho hanyetsa sulfate. Mohlala, 1% ea fiberglass e ka fokotsa li-coefficients tsa phallo ea chloride ka 20% -30%.
Ts'ebetso ea nako e telele: Ho tšoarella ha likhoele libakeng tsa alkaline ho hloka tlhokomelo. Mekhabiso e thibelang alkali kapa likhoele tse nyalisitsoeng (mohlala, tse nang le polypropylene) li ntlafatsa bophelo bo bolelele.
Meeli: Likhakanyo tsa boleng bo tlase tse sebelisoang hape (mohlala, porosity e phahameng, litšila) li ka fokotsa melemo ea fiber.
6. Litlhahiso tsa Kopo
Maemo a loketseng: Litikoloho tsa leoatle, mobu oa letsoai, kapa meaho e hlokang konkreite e nchafalitsoeng e tšoarellang nako e telele.
Katoloso ea Motsoako: Tekanyo ea litekanyetso tsa faeba, tekanyo e nchafalitsoeng e kopantsoeng hape, le likhokahano le li-additives (mohlala, mosi oa silica).
Taolo ea boleng: Etsa bonnete ba ho hasana ha fiber e ts'oanang ho qoba ho kopana nakong ea ho kopanya.
Kakaretso
Fiberglass e matlafatsa khanyetso ea khoholeho ea konkreite e nchafalitsoeng ka ho tiisa 'mele le botsitso ba lik'hemik'hale. Ho sebetsa ha eona ho ipapisitse le mofuta oa fiber, litekanyetso, le boleng bo kopantsoeng hape. Lipatlisiso tsa nako e tlang li lokela ho shebana le ho tšoarella ha nako e telele le mekhoa ea tlhahiso e baballang chelete e ngata ho tsamaisa lits'ebetso tse kholo tsa boenjiniere.
