Phello ea Basalt Fiber ho Ts'ebetso ea Konkreite e Permeable
Basalt fiber, e le buka ea "inorganic", e sebetsang hantle haholo le eco-friendly, e ntlafatsa haholo thepa ea mochini, ho tšoarella, le ts'ebetso ea konkreite e kenang. Ka tlase ke tlhahlobo ea mefuta e mengata ea litlamorao le liparamente tsa ntlafatso:
- Tšusumetso ho Thepa ea Mechini
Matla a Ntlafetseng a Compressive le Flexural
Basalt fiber matlafatso e ntlafatsa ka katleho matla a hatellang le a feto-fetohang a konkreite e kenang. Liphuputso li bontša hore likhoele li etsa sebopeho sa marang-rang se mahlakore a mararo, se matlafatsang maqhama pakeng tsa li-aggregates le sekontiri sa samente ha se ntse se thibela ho ata ha crack. Ka mohlala:
Matla a Khatellang: Ka likhoele tsa 12 mm le 24 mm, matla a khatello a qala a eketseha ebe a fokotseha ka fiber e phahameng. Tekanyetso e nepahetseng ke 0.1% -0.15% (ka molumo), ka likhoele tsa 24 mm tse fihlelang matla a holimo a 24.3 MPa (ka tekanyo ea 0.1%).
Flexural Strength: Bolelele ba fiber bo na le phello e hlakileng haholoanyane ho matla a flexural. Mohlala, likhoele tsa 18 mm li eketsa matla a ho feto-fetoha ka 66.44% ha li bapisoa le konkreite e hlakileng ka lebaka la maqhama a matla a sefahleho ho tsoa ho khokahanyo e kopaneng ea fiber.
Matla a Eketsehileng le Ductility
"Phello ea borokho" ea Basalt Fibers e ntlafatsa ho tiea, ho fetola mekhoa ea ho hlōleha ho tloha ho brittle ho ea ho ductile. Tlhahlobo ea microscopic e senola hore likhoele li tsitsisa sebopeho sa skeleton ka har'a matrix ea samente, e thibelang kholo ea crack ka katleho.
Tšusumetso ho Permeability
Phokotso ea Permeability Coefficient
Ho kenngoa ha fiber ka mokhoa o itseng ho thibela li-pores, ho theola ho kenella ha metsi. Ka mohlala, ho eketsa fiber content ho tloha 0.05% ho 0.2% butle-butle ho fokotsa coefficient ea permeability, leha ho le joalo e ntse e kopana le litlhaloso (mohlala, permeability> 1 mm / s ho 20% porosity).
Ho leka-lekanya Porosity le Fiber Parameters
Likhoele tse telele (mohlala, 12 mm → 24 mm) li eketsa porosity hanyenyane empa li ntse li fokotsa ho phunyeletsa.
Ho kopanya likhoele le metsoako ea liminerale (mohlala, molora oa fofa) ho ntlafatsa sebopeho sa pore, ho fokotsa tahlehelo ea ho kenella ha o ntse o boloka matla.
- Ntlafatso ea Khanyetso ea Frost
Likhoele tsa Basalt ntlafatsa sebopeho sa sebopeho sa kahare, ho matlafatsa ho hanyetsa serame haholo:
Kamora 'lipotoloho tse 100 tsa ho qhibiliha, mehlala e matlafalitsoeng ka fiber e bonts'a sekhahla sa tahlehelo e tlase ho 0.9% mme e boloka 62.5% e amanang le dynamic elastic modulus.
Tšebelisano le molora oa lintsintsi (mohlala, 6% fly ash + 6kg/m³ fibers) e khona ho mamella serame, kaha molora oa lintsintsi o ntlafatsa pore ha likhoele li hatella ho phatloha ha leqhoa.
- Li-Parameters tsa Ts'ebetso ea Bohlokoa
Fiber Length: 24 mm likhoele li buelloa bakeng sa ho leka-lekanya matla le ho khoneha, le hoja likhoele tsa 18 mm li ipabola ka matla a flexural.
Range ea Litekanyetso: 0.1%–0.15% ka bophahamo (kapa 2–6 kg/m³ ka boima). Tekanyetso e feteletseng e beha likotsi tsa fiber agglomeration le ho fokotsa ts'ebetso.
Lisebelisoa tsa Synergistic: Molora o fofang (6% -15%) kapa silica fume (6% -9%) e ntlafatsa thepa ea mochini le ho fokotsa tahlehelo ea ho kenella.
- Litlhahiso tsa Kopo
Scenarios: E nepahetse bakeng sa litsela tsa maoto, mabala le libaka tse batang tse hlokang ho kenella le matla.
Kaho: Sebelisa mokhoa oa ho kopanya "samente-coated aggregate" ho etsa bonnete ba ho hasana ha fiber e ts'oanang le ho qoba ho kopana.
Ka kakaretso, fiber ea basalt e ntlafatsa sebopeho sa microstructure le ts'ebetso ea mochini oa konkreite e khonang ho kenella, empa taolo e tiileng ea litekanyetso le litekanyetso tsa ts'ebetso e bohlokoa ho leka-lekanya matla le ho kenella. Patlisiso ea nako e tlang e lokela ho shebana le phetoho ea fiber surface le synergy ea lisebelisoa tse ngata ho hlola meeli ea ts'ebetso ea hajoale.
