Ucwaningo ngokumelana nokugqwala kukakhonkolo we-basalt fiber ukusiza ukuthuthukisa ukuqina kwekhonkrithi

Ucwaningo mayelana nokumelana nokugqwala kwe I-Basalt Fiber ukhonkolo ukhombisa ukuthi ukuxutshwa kwenani elifanele leimicu ye-basalt ingathuthukisa kakhulu ukumelana nokugqwala kukakhonkolo, okunikeza umbono omusha wokuxazulula inkinga yokuwohloka kokuqina okubangelwa ukugqwala kwekhonkrithi.
Ukugqwala kukakhonkolo kungenye yezimbangela ezibalulekile zokuwohloka kokuqina kwayo, okuletha ukulahlekelwa okukhulu kwezomnotho minyaka yonke. Ukuze kuncishiswe ukulahlekelwa kwezomnotho okubangelwa ukugqwala kukakhonkolo, kubaluleke kakhulu ukufunda ukumelana nokugqwala kwe-corrosion. i-basalt fiberukhonkolo. Njengamanje, ucwaningo olufanele lusetshenziswa ikakhulukazi I-Concrete Specimen igxile kuzixazululo ezihlukene zokugqwala ukuze ihlaziye izinguquko emandleni ayo acindezelayo, amandla aguquguqukayo nezinye izici.

Okutholakele ocwaningweni:

• Amandla acindezelayo namandla e-flexural: amandla acindezelayo kanye namandla aguquguqukayo we i-basalt fiber ukhonkolo uyancipha ngokukhula kokugxila kwesisombululo esigqwalayo kanye nesikhathi sokugqwala, kodwa ukuxutshwa kwenani elifanele lemicu ye-basalt kungathuthukisa kakhulu amandla awo acindezelayo namandla okuguquguquka endaweni ebolayo. Kodwa-ke, ukufakwa ngokweqile kwe-basalt fibers kuzoholela ekunciphiseni amandla.
• Impahla yokulwa nokuqhekeka: Ngemuva kokucwiliswa kusixazululo se-sodium sulfate izinsuku ezingama-90, impahla yokulwa nokuqhekeka i-basalt fiber ukhonkolo wathuthukiswa kakhulu, umphumela omuhle kakhulu watholakala lapho ukuhlanganiswa kwevolumu ye-basalt fiber kungu-0.1%.
• Ukuvimbela i-crack: ngemuva kokucwiliswa kusixazululo se-sodium chloride izinsuku ezingama-90, izinsuku eziyi-180 nezinsuku ezingama-270, i-basalt fiber ingavimbela ngempumelelo ukuthuthukiswa kokuqhekeka kwangaphambi kwesikhathi kukhonkolo, ngokusebenza okuhle kakhulu kokulwa nokuqhekeka lapho umthamo wevolumu ungu-0.1%.
• Amandla okuguqula kanye nomthamo wokugcina wokuthwala: ukuhlolwa okucindezelayo kwezibonelo ezifakwe kwisisombululo esigqwalayo kubonise ukuthi ukungezwa kwemicu ye-basalt kungathuthukisa umthamo wokuguqulwa kanye nomthamo wokugcina wokuthwala ukhonkolo, futhi umphumela ulungile uma umthamo wevolumu ungu-0.1%.

Nakuba izifundo ezikhona ziqinisekisile umphumela omuhle wemicu ye-basalt ekumelaneni nokugqwala kukakhonkolo, izifundo eziningi zamanje zigxile esimweni esisodwa sokugqwala (isb, i-sulfate noma i-chloride corrosion), futhi kunezifundo ezimbalwa ezixazululweni ezixubile zezinto eziningi ezigqwalayo. Ukwengeza, ucwaningo olukhona lukhathazeke kakhulu ngomphumela we-fiber admixture ezicini zemishini, isidingo sesikhathi esizayo sokuqhubeka nokuthuthukisa ukuguguleka kwe-ion eyingozi namandla okungena kanye nezinye izici zocwaningo.
Ochwepheshe bathi ucwaningo lwekhonkrithi ye-basalt fiber lunikeza ukwesekwa okubalulekile kwezobuchwepheshe ukuze kuthuthukiswe ukuqina kukakhonkolo, futhi kulindeleke ukuthi kusetshenziswe kabanzi kwezobunjiniyela basolwandle, izikhungo zamakhemikhali nezinye izindawo ezigqwalile esikhathini esizayo.
