Umthelela we-fiberglass ekumelaneni nokhonkolo ovuselelwe kabusha

Ithonya le-fiberglass ekumelaneni kukakhonkolo okuvuselelwa kabusha (okwenziwe kusuka kuma-concreete ukhonkolo asetshenzisiwe) yisihloko sentshisekelo enkulu kwi-workes science kanye nezobunjiniyela bomphakathi. Ngenkathi ukhonkolo ovuselelwe kabusha unikeza izinzuzo zezemvelo nezisetshenziswa kabusha, izakhiwo zalo zemishini nokuqina (isib. Ukumelana nokuguguleka) kuvame ukwenziwa phansi kokhonkolo ojwayelekile. I-fiberglass, njengeUkuqiniswa Kwezinto, kungathuthukisa ukusebenza ngokhonkolo ovuselelwe kabusha ngokusebenzisa izindlela zomzimba nangamakhemikhali. Nakhu ukuhlaziya okuningiliziwe:

1. Izakhiwo nemisebenzi yeIjibha

I-fiberglass, izinto ezingeyona eyezinhlaka, kukhombisa lezi zici ezilandelayo:
Amandla aphezulu aphezulu: anxephezele umthamo ophansi we-conkcrete.
Ukumelana nokugqwala: phikisana nokuhlaselwa kwamakhemikhali (isib. Chloride ion, sulfates).
Ukuvimbela Ukumelana Nekuqhekeka **: Amabhuloho ama-Microcracks ukuzembezele ukuqhekeka kokuqhekeka futhi anciphise ukuvumela.

2. Ukushiyeka kokuqina kokhonkolo ovuselelwe kabusha

Ama-aggregate asetshenziswe kabusha ane-POROUS SUMPER CEAND CASTE emikhawulweni yawo eholile ku:
Indawo Ebuthakathaka Yokushintshana Kwezintuthuko (i-ITZ): Ukubopha okumpofu phakathi kwama-aggregate asetshenzisiwe kanye nohlolo olusha lwesimende, ukudala izindlela ezivunyelwe.
Okungaphambi Kokungabonakali Kwe-Low Exermeability: Ama-ejenti ama-erosive (isib. Cl⁻, So₄²⁻) angene kalula, okwenza ukugqwala kwensimbi noma ukulimala kwento.
Ukumelana kweqhwa okumpofu

3. Izindlela ze-fiberglass ekwenzeni ngcono ukumelana nokuguguleka

(1) imiphumela yokuvimba ngokomzimba
Ukuvinjelwa kwe-Crack: Imicu ehlakazekile ehlakazekile ibhulogi ibhuloho le-microcracks, ivimba ukukhula kwayo kanye nokunciphisa izindlela ze-ejenti ezikhulayo.
Ukuhlanganiswa okuthuthukile: Imicu igcwalisa ama-pores, wehlisa i-poorlity futhi yehlise ukuguquguquka kwezinto eziyingozi.

(2) Ukuqina kwamakhemikhali
I-ALkali-Ukumelana ne-fiberlass(isib., i-ar-ingilazi)
Ukuqiniswa kwe-interface: Ukubopha okuqinile kwe-fiber-matrix Bonding kunciphisa amaphutha e-ITZ, kunciphisa ubungozi obuqalekiswe bendawo.

(3) Ukumelana nezinhlobo ezithile zokuguguleka
Ukumelana ne-Chloride ion
Ukumelana Nokuhlasela kweSulfate: Ukukhula okucindezelwe ukukhuphuka kunciphisa ukulimala kusuka ku-sulfate crystallization kanye nokwanda.
Ukuqina kweqhwa - ukuqina kwe-fiber kuthola ukucindezelwa kusuka e-Ice.

4. Izici ezinomthelela obalulekile

Umthamo wefayibha: Uhla oluphelele lungu-0.5% -2% (ngevolumu); imicu eyeqile ibangela ukuhlanganisa futhi inciphise ukuhlanganiswa.
Ubude be-fiber nokuhlakazeka: imicu emide (12-24 mm) Thuthukisa ama-hisning kodwa adinga ukusatshalaliswa komfaniswano.
Ikhwalithi yama-aggregate asetshenziswe kabusha

5. Ukutholwa kocwaningo kanye neziphetho ezisebenzayo

Imiphumela emihle: Izifundo eziningi zikhombisa lokho kufaneleijibhaNgaphezu kwalokho kuthuthukisa kakhulu ukungakhathali, ukumelana kwe-chloride, kanye nokumelana kwe-sulfate. Isibonelo, i-1% fiberglass inganciphisa ama-coefficience we-chloride we-chloride nge-20% -30%.
Ukusebenza kwesikhathi eside: ukuqina kwemicu ezindaweni ze-alkaline kudinga ukunakwa. Izambatho ezivimbela ukumelana noma imicu ye-hybrid (isib. Nge-polypropylene) ngcono ukuthuthukisa isikhathi eside.
Ukulinganiselwa: Ikhwalithi esetshenzisiwe esetshenziselwe phansi (isib. I-High Popolity, Ukungcola) kunganciphisa izinzuzo ze-fiber.

6. Izincomo zohlelo lokusebenza

Izimo ezifanele: Izindawo zasolwandle, inhlabathi ye-saline, noma izakhiwo ezidinga ukuqina okuphezulu kokhonkolo.
Hlanganisa kahle: Ukuhlolwa komthamo wefayibha, i-RecyCled Aggregate Replathe Ratio, kanye nama-synergies ngezengezo (isib. Isilayidi se-silica).
Ukulawulwa kwekhwalithi: Qinisekisa ukuhlakazeka kwe-fiber okufanayo ukugwema ukuqina ngesikhathi sokuxuba.

Ukubeka kafushane

I-fiberglass ithuthukisa ukumelana nokuguguleka kokhonkolo ovuselelwe kabusha ngokusebenzisa okunamandla ngokomzimba kanye nokuqiniswa kwamakhemikhali. Ukusebenza kwayo kuncike kuhlobo lwe-fiber, umthamo, nekhwalithi yokuhlanganisa kabusha. Ucwaningo lwesikhathi esizayo kufanele lugxile ekuweni isikhathi eside kanye nezindlela zokukhiqiza ezingezindleko ezisebenzayo ukwenza lula izinhlelo zokusebenza zobunjiniyela obukhulu.
