Umphumela we-Basalt Fiber ekusebenzeni kwekhonkrithi evulekayo
I-Basalt fiber, njengezinto ezintsha ezingaphili, ezisebenza kahle kakhulu, futhi ezinobungani nemvelo, zithuthukisa kakhulu izakhiwo zemishini, ukuqina, kanye nokusebenza kwekhonkrithi engenela amanzi. Ngezansi ukuhlaziywa okunezinhlangothi eziningi kwemiphumela yayo kanye nemingcele yokwenza ngcono:
- Umthelela Ezimpahleni Zemishini
Amandla Okucindezela Nokuguquguquka Athuthukisiwe
I-Basalt fiber Ukuqinisa kuthuthukisa ngempumelelo amandla okucindezela kanye nokuguquguquka kwekhonkrithi engenela amanzi. Izifundo zibonisa ukuthi imicu yakha isakhiwo senethiwekhi esinezinhlangothi ezintathu, iqinisa ukubopha phakathi kwama-aggregates kanye ne-cement paste ngenkathi ivimbela ukusabalala kwemifantu. Isibonelo:
Amandla Okucindezela: Ngemicu engu-12 mm no-24 mm, amandla okucindezela ayanda ekuqaleni bese ehla uma okuqukethwe kwemicu kuphezulu. Umthamo ofanele kakhulu ngu-0.1%–0.15% (ngomthamo), lapho imicu engu-24 mm ifinyelela amandla okucindezela aphezulu angu-24.3 MPa (ngomthamo ongu-0.1%).
Amandla Okugobeka: Ubude befayibha bunomthelela ocacile emandleni okugobeka. Isibonelo, imicu engu-18 mm ikhulisa amandla okugobeka ngo-66.44% uma kuqhathaniswa nokhonkolo oluvamile ngenxa yokuqina kokubopha kwe-interfacial okuvela ekuxhumeni okwandisiwe kwe-fiber-aggregate.
Ukuqina Okuthuthukisiwe Nokuqina
"Umphumela wokuhlanganisa" we I-Basalt Fibers ithuthukisa ukuqina, ishintsha izindlela zokwehluleka kusuka ekuqhekekeni kuya ekuqhekekeni. Ukuhlaziywa kwe-Microscopic kwembula ukuthi imicu izinzisa isakhiwo samathambo ngaphakathi kwe-matrix yesimende, ivimbele ngempumelelo ukukhula kwemifantu.
Umthelela Ekuvumelekeni Kokuvunyelwa
I-Coefficient Yokuvunyelwa Kokuncishiswa
Ukufakwa kwefayibha kuvimbela kancane ama-pores, kunciphisa ukuvuleka. Isibonelo, ukwandisa okuqukethwe kwefayibha kusuka ku-0.05% kuya ku-0.2% kunciphisa kancane kancane i-permeability coefficient, kodwa kusahlangabezana nezimfuneko (isb., ukuvuleka >1 mm/s ku-20% porosity).
Ukulinganisela i-Porosity kanye ne-Fiber Parameters
Imicu emide (isb., 12 mm → 24 mm) ikhulisa kancane ukubhoboka kodwa isanciphisa ukungena kwamanzi.
Ukuhlanganisa imicu nezingxube zamaminerali (isb. umlotha wezimpukane) kuthuthukisa isakhiwo sezimbobo, kunciphisa ukulahleka kokungena kwamanzi ngenkathi kugcinwa amandla.
- Ukumelana Nokuqhwa Okuthuthukisiwe
Imicu ye-basalt kuthuthukisa ubuqotho besakhiwo sangaphakathi, okwandisa kakhulu ukumelana nesithwathwa:
Ngemva kwemijikelezo eyi-100 yokuqandisa, amasampula aqiniswe ngefayibha abonisa izinga lokulahlekelwa isisindo elingaphansi kuka-0.9% futhi agcina i-62.5% ye-relative dynamic elastic modulus.
Ukusebenzisana nomlotha wezimpukane (isb., umlotha wezimpukane ongu-6% + imicu engu-6 kg/m³) kufeza ukumelana okuhle kakhulu nesithwathwa, njengoba umlotha wezimpukane ulungisa isakhiwo sezimbobo kuyilapho imicu icindezela ukuqhekeka kokuqandisa nokuncibilika.
- Amapharamitha Okuthuthukisa Ukhiye
Ubude be-Fiber: Kunconywa imicu engu-24 mm ukuze kulinganiswe amandla kanye nokuvuleka, yize imicu engu-18 mm iphumelela kakhulu ekuqineni kwe-flexural.
Ibanga Lomthamo: 0.1%–0.15% ngevolumu (noma 2–6 kg/m³ ngesisindo). Umthamo oweqile ubeka engcupheni ukuhlanganiswa kwefayibha kanye nokusebenza okunciphile.
Izinto Ezihambisanayo: Umlotha ondizayo (6%–15%) noma i-silica fume (6%–9%) kuthuthukisa kakhulu izakhiwo zemishini futhi kunciphisa ukulahleka kokungena kwamanzi.
- Izincomo Zohlelo Lokusebenza
Izimo: Zilungele izindlela zokuhamba ngezinyawo, izindawo zokupaka, kanye nezindawo ezibandayo ezidinga kokubili ukungena kwamanzi kanye namandla.
UkwakhiwaSebenzisa indlela yokuxuba "i-aggregate embozwe ngosimende" ukuqinisekisa ukusabalala okufanayo kwefayibha nokugwema ukugoqana.
Ngamafuphi, i-basalt fiber yenza ngcono isakhiwo esincane kanye nokusebenza komshini kwekhonkrithi evumayo, kodwa ukulawulwa okuqinile kwesilinganiso kanye nemingcele yenqubo kubalulekile ukuze kulinganiswe amandla kanye nokuvuleka. Ucwaningo lwesikhathi esizayo kufanele lugxile ekuguqulweni kobuso be-fiber kanye nokusebenzisana kwezinto eziningi ukuze kunqotshwe imikhawulo yokusebenza yamanje.
