Zaruruwan Basalt Suna Inganta Juriyar Carbonation na Siminti
I. Tsarin aikin hana carbonation: inganta haɗin gwiwa mai girma dabam-dabam
1. Tsarin rami da kuma hana tsagewa
Zaruruwan basalt yana hana fashewar filastik da wuri a cikin siminti (rage faɗin 30%-50%) da kuma toshe hanyoyin watsawa na CO₂ ta hanyar rarraba raga mai girma uku. Kayayyakin ruwa masu yawa da aka samar a hanyar haɗin fiber-matrix na iya rage yawan ramuka masu cutarwa (>100 nm) daga 18.6% zuwa 12.3%, wanda hakan ke rage yawan iskar da ke shiga.
2. Daidaita ruwa da kuma Sinadaran sinadarai haɗin gwiwa
Rashin kyawun saman zare yana haɓaka nau'in gel na CSH, yana hanzarta amsawar ruwa, matakin ruwa na kwanaki 28 ya karu da kashi 8%-12%. Lokacin da aka haɗa shi da ma'adanai (misali, hayakin silica), tasirin tokar aman wuta tare da tasirin hana karyewar zare yana rage jimlar porosity da kashi 40%, kuma rabon pores marasa lahani (
II. Aikin injiniya da fa'idodin tattalin arziki
1. Rayuwar hanya ta faɗaɗa sosai
Babban aiki Basalt fiber An yi bincike kuma an ƙirƙiro simintin kwalta wanda Jami'ar Yangzhou ta gudanar, juriyar ruɓewa ta ƙaru da kashi 20%-40%, juriyar tsagewa ta ƙaru da sau 2-8, zagayowar kulawa ta ƙaru daga shekaru 3-5 zuwa shekaru 6-8, tanadin kuɗin gyara na dogon lokaci ya ragu sosai.
2. Inganta aikin simintin da aka sake yin amfani da shi
Bincike ya nuna cewa idan aka haɗa simintin da aka sake yin amfani da shi (RAC) da zare na basalt 2 kg/m³, zurfin carbonation yana raguwa da kashi 41% idan aka kwatanta da simintin da aka sake yin amfani da shi na yau da kullun, kuma ana samun mafi kyawun juriya ga carbonation tare da kashi 50% na yawan maye gurbin da aka sake yin amfani da shi.
III. Yanayin da Kalubale na Gaba
1. Binciken haɗin gwiwa da yawa
Ana buƙatar ƙarin bincike kan aikin dogon lokaci a ƙarƙashin haɗin gishiri na carbonation-chloride, bayanai na farko sun nuna cewa ƙimar carbonation na simintin zare ƙasa da sau 0.5 na babban nauyin har yanzu yana ƙasa da kashi 28%.
2. Haɗin sa ido mai hankali
Dasa fiber na gani da hanyar sadarwa ta fiber mai fahimtar carbonation, bin diddigin gaban carbonation a ainihin lokaci (daidai ± 0.1 mm), samar da tallafin bayanai don kiyaye kariya.
Basalt fiber yana samar da mafita mai matakai da yawa don juriya ga carbonation ta hanyar inganta tsarin microstructure da haɓaka aikin macro. Tare da inganta tsarin yau da kullun da sabbin fasahohi, za a faɗaɗa aikace-aikacensa daga hanyoyi da gadoji zuwa injiniyan ruwa da sauran fannoni, wanda ke haɓaka dorewar kayayyakin more rayuwa zuwa sabon zamani.
