1. Babban umarnin aikace-aikace
- Kayan ƙarfafa siminti
Simintin Zare (BFRC): Gajeren zaɓi Basalt fiberAna haɗa s (6-24mm) a cikin siminti (adadin haɗuwa 0.1%-0.5%), wanda zai iya inganta juriyar tsagewa sosai (rage faɗin tsagewa da 30%-50%), juriyar tasiri (ƙara da sau 2-3), da kuma dorewa (ƙara juriyar zagayowar daskarewa da narkewa da 40%).
Sauya ƙarfin ƙarfafa ƙarfe: A cikin muhallin da ke lalata abubuwa (misali injiniyan ruwa), sandunan ƙarfafa fiber na basalt (sandunan BFRP) na iya maye gurbin ƙarfafa ƙarfe don guje wa matsalolin tsatsa. Misali, amfani da bfrp Ana sa ran ƙarfafawa a cikin mashigar gadar da ke tsakanin teku da birnin Qingdao zai tsawaita tsawon rayuwarta zuwa fiye da shekaru 100.
- Ƙarfafawa da gyara gine-gine
Zane/Rage Rage: Ana liƙa zaren zaren Basalt (ƙarfin tauri ≥2000MPa) a saman katako da ginshiƙai, wanda zai iya ƙara ƙarfin ɗaukar kaya da kashi 20%-30%. Misali, bayan an ƙarfafa tsohuwar gada a Sichuan da zane BF, ana ɗaukaka ƙimar kaya daga Babbar Hanya-II zuwa Aji na I.
Ƙarfafa girgizar ƙasa: haɗakar da aka ƙarfafa da zare (BFRP) ginshiƙan siminti da aka naɗe, waɗanda za su iya haɓaka sassauci da ƙarfin amfani da makamashi, kuma sun dace da gine-gine a wuraren da girgizar ƙasa ke iya faruwa.
- Sabbin tsarin haɗin gwiwa
Bangarorin sanwicin basalt fiber-polymer: ana amfani da su don rufin gida mai sauƙi da bangon rabuwa, tare da ƙarfi mai yawa da kuma rufin zafi (ƙarfin wutar lantarki ≤ 0.05 W/mK).
Kayan gini na bugu na 3D: zare mai siffar basalt- kayan siminti masu ƙarfi na iya aiwatar da bugu mai rikitarwa da rage sharar gini.

| Manuniyar Aiki | Basalt fiber | Kayan kwatantawa (zaren gilashi) |
| Ƙarfin tauri | 3000-4800 MPa | 2000-3500 MPa |
| Juriyar Alkali (pH=13) | Riƙe ƙarfi ≥90% | Zaren gilashi: riƙe ƙarfi ≤ 50% |
| Fa'idodin muhalli: amfani da makamashin samarwa shine kashi 30% kawai na zare na gilashi, kuma ana iya sake yin amfani da shi 100%. | ||
3. Ci gaban Bincike da Lamura na Yau da Kullum
- Binciken cikin gida
Jami'ar Tsinghua: an ƙera simintin basalt fiber-nano-silica wanda aka gyara tare da ƙaruwar ƙarfin matsi 25% da kuma rage yawan iskar chloride ion 60%.
Jami'ar Kudu maso Gabas: an gabatar da fasahar BF/epoxy resin laminate mai ƙarfafa ƙarfin siminti, tsawon lokacin gajiya ya ninka sau 3.
- Aikace-aikacen ƙasa da ƙasa
Japan: Bayan girgizar ƙasa ta Hanshin, wani babban gini a Osaka ya rungumi katangar yanke raga ta BF, kuma aikin girgizar ƙasa ya inganta da kashi 40%.
Turai: An yi amfani da siminti mai ƙarfi na BF a ƙofofin hana ambaliyar ruwa a Venice, Italiya, wanda tsawon rayuwarsa ya kai shekaru 50 a kan zaizayar ruwan teku.
- Lambobin Injiniya
China - Gadar Hong Kong-Zhuhai-Macao: Basalt fiber Ana amfani da kayan haɗin gwiwa a cikin layin hana lalata wasu madaukai, wanda ke rage farashin gyara da kashi 30%.
Amurka - San Francisco Bay Area (BART): Ana amfani da yadin BF wajen ƙarfafa rufin rami, kuma juriyar nakasa ta ƙaru da kashi 25%.
4. Kalubale da Umarni na Gaba
- Matsalolin da ke akwai
Rashin isasshen aikin haɗin fuska: haɗin da ke tsakanin zare da siminti/resin yana da saurin cirewa, ana buƙatar haɓaka sabbin abubuwan haɗin gwiwa (misali, masu gyara silane).
Rashin bayanan aiki na dogon lokaci: halayen ɓurɓuwa na ƙarfafa BF a ƙarƙashin yanayin zafi mai yawa da zafi mai yawa (fiye da shekaru 10 na bayanai har yanzu ba a kammala su ba).
Daidaiton tsarin da aka saba amfani da shi: ƙayyadaddun ƙirar injiniya don kayan BF a ƙasashe daban-daban ba a tabbatar da su sosai ba tukuna (China ta fitar da GB/T 38143-2019, amma cikakkun bayanai na aikace-aikacen za a inganta su).
- Alkiblar bincike a nan gaba
Haɗaɗɗun zare masu hankali: na'urori masu auna sigina da aka haɗa don cimma sa ido kan lafiyar tsarin (misali, tauri, sanin kai).
Fasahar shirye-shiryen kore: rage zafin narkewa da zane (a halin yanzu yana buƙatar 1400-1500℃), da kuma haɓaka tsarin ƙarancin carbon.
Ƙarfafa haɗin gwiwa mai girma dabam-dabam: haɗawa da zare na carbon da zare na ƙarfe don gina haɗakar gradient.
5. Takaitaccen Bayani
Aikace-aikacen zare mai siffar basalt a fannin injiniyancin farar hula ya koma daga dakin gwaje-gwaje zuwa aikin injiniya, kuma halayensa masu inganci da kuma masu kyau ga muhalli sun dace da buƙatar gine-ginen kore a ƙarƙashin manufar "dual-carbon". A nan gaba, ya zama dole a karya hanyoyin inganta hanyoyin sadarwa, tabbatar da dorewar dogon lokaci da sauran manyan fasahohi, sannan a lokaci guda a inganta haɓaka ƙayyadaddun ƙira da haɗin gwiwar sarkar masana'antu, domin hanzarta amfani da shi a manyan kayayyakin more rayuwa, injiniyancin ruwa, rigakafin girgizar ƙasa da bala'i da sauran yanayi.
