Imicu yeBasalt Ithuthukisa Ukumelana Ne-Carbonation Kokhonkolo
I. Indlela yokusebenza yokulwa ne-carbonation: ukulungiswa kokubambisana ngezinga elihlukahlukene
1. Isakhiwo sembobo kanye nokuvinjelwa kokuqhekeka
Imicu ye-basalt vimbela ukuqhekeka kwepulasitiki ekuqaleni kokhonkolo (ukwehla okungu-30%-50% kobubanzi) futhi uvimbele izindlela zokusabalalisa ze-CO₂ ngokusatshalaliswa kwe-mesh enobukhulu obuthathu. Imikhiqizo yokumanzisa okujiyile ekhiqizwa esibonakalayo se-fiber-matrix inganciphisa isilinganiso sama-pores ayingozi (>100 nm) kusuka ku-18.6% kuya ku-12.3%, okunciphisa kakhulu ukugeleza kwamanzi.
2. Ukuguqulwa kwamanzi kanye Amakhemikhali ukusebenzisana
Ukungalungi kobuso be-fibre kukhuthaza i-CSH gel nucleation ehlukahlukene, kusheshiswe ukusabela komswakama, izinga lomswakama lezinsuku ezingu-28 likhuphuke ngo-8%-12%. Uma lihlanganiswa nezingxube zamaminerali (isb., i-silica fume), umphumela womlotha wentaba-mlilo ohambisana nomphumela wokunciphisa ukuqhekeka kwe-fibre wehlisa i-porosity iyonke ngo-40%, kanti isilinganiso sama-pores angenangozi (
II. Umkhuba wobunjiniyela kanye nezinzuzo zomnotho
1. Impilo yomgwaqo yande kakhulu
Ukusebenza okuphezulu I-Basalt Fiber ukhonkolo we-asphalt ocwaningwe futhi wathuthukiswa yiYangzhou University, ukumelana nokugoba kukhuphuke ngo-20%-40%, ukumelana nokuqhekeka kokukhathala kukhuphuke ngokuphindwe kabili kuya kasishiyagalombili, umjikelezo wokulungisa wanda kusukela eminyakeni emi-3-5 kuya eminyakeni eyi-6-8, ukonga izindleko zokulungisa isikhathi eside kuncishiswe kakhulu.
2. Ukusebenza okuthuthukisiwe kwekhonkrithi ephinde yasetshenziswa
Ucwaningo lubonisa ukuthi uma ikhonkrithi ehlanganisiwe ephinde yasetshenziswa (i-RAC) ixutshwa nemicu ye-basalt engu-2 kg/m³, ukujula kwe-carbonation kuncishiswa ngo-41% uma kuqhathaniswa nekhonkrithi ehlanganisiwe evamile, futhi ukumelana okungcono kakhulu kwe-carbonation kutholakala ngesilinganiso sokushintshana kwekhonkrithi ehlanganisiwe ephinde yasetshenziswa esingu-50%.
III. Izitayela Nezinselele Zesikhathi Esizayo
1. Ucwaningo lokuhlanganisa amasimu amaningi
Kudingeka sihlole kabanzi ukusebenza kwesikhathi eside ngaphansi kokuhlanganiswa kosawoti we-carbonation-chloride, idatha yokuqala ikhombisa ukuthi izinga le-carbonation lekhonkrithi yefayibha elingaphansi kwezikhathi ezingu-0.5 lomthwalo wokugcina lisaphansi ngo-28%.
2. Ukuhlanganiswa kokuqapha okuhlakaniphile
Ukufakelwa kwe-fiber optical kanye nenethiwekhi ye-fiber ezwa i-carbonation, ukulandelela ngesikhathi sangempela i-carbonation front (ukunemba ± 0.1 mm), okunikeza ukwesekwa kwedatha yokulungisa okuvinjelwe.
I-Basalt fiber inikeza ikhambi lamazinga amaningi lokumelana ne-carbonation yekhonkrithi ngokusebenzisa ukulungiswa kwesakhiwo esincane kanye nokuthuthukiswa kokusebenza kwe-macro. Ngokuthuthukiswa kohlelo olujwayelekile kanye nokusungula izinto ezintsha kwezobuchwepheshe, ukusetshenziswa kwalo kuzokwandiswa kusukela emigwaqweni nasemabhuloho kuya kobunjiniyela basolwandle kanye neminye imikhakha, kuthuthukiswe ukuqina kwengqalasizinda kuze kube senkathini entsha.
