Mafiber eBasalt Anowedzera Kuramba Kwekongiri Kugadzira Carbonation
I. Maitiro ekurwisa kabhoni: kugadzirisa kubatana kwemhando dzakasiyana-siyana
1. Maumbirwo eburi uye kudziviswa kwekuputika
Fiber dzebasalt Kudzivirira kupwanyika kwepurasitiki kwekutanga kwekongiri (kuderedzwa kwehupamhi hwe30%-50%) uye kudzivirira nzira dzeCO₂ diffusion kuburikidza nekugoverwa kwemesh kwemativi matatu. Zvigadzirwa zve dense hydration zvinogadzirwa pa fiber-matrix interface zvinogona kuderedza huwandu hwema pores ane njodzi (>100 nm) kubva pa18.6% kusvika pa12.3%, zvichideredza zvakanyanya kupenya kwemvura.
2. Kuchinja kwemvura mumuviri uye Kemikari kubatana
Kuomarara kwepadenga re fiber kunokurudzira CSH gel ine nucleation yakasiyana-siyana, zvichikurumidzisa hydration reaction, hydration degree yemazuva makumi maviri nemasere yakawedzera ne8%-12%. Kana ikasanganiswa nemamineral admixtures (semuenzaniso, silica fume), volcanic ash effect pamwe chete nefiber fracture-limiting effect zvakaderedza total porosity ne40%, uye chikamu chemapores asina njodzi (
II. Maitiro einjiniya uye mabhenefiti ehupfumi
1. Hupenyu hwemugwagwa hwakareba zvakanyanya
Kushanda kwepamusoro Basalt Fiber Konkriti yeasphalt yakatsvakurudzwa uye yakagadzirwa neYangzhou University, kuramba maburi kwakawedzera ne20%-40%, kuramba kuneta nekupwanyika kwakawedzera nekaviri-kasere, nguva yekugadzirisa yakawedzera kubva pamakore 3-5 kusvika kumakore 6-8, kuchengetedza mari yekuchengetedza kwenguva refu kwakadzikira zvakanyanya.
2. Kuvandudzwa kwekushanda kwekongiri yakadzokororwa
Tsvagiridzo inoratidza kuti kana kongiri yakasanganiswa (RAC) ikasanganiswa ne2 kg/m³ basalt fibers, kudzika kwecarbonation kunoderedzwa ne41% zvichienzaniswa nekongiri yakadzokororwa, uye kuramba kwakanakisa kwecarbonation kunowanikwa ne50% recycled aggregate substitution rate.
III. Mafambiro Nematambudziko Eramangwana
1. Tsvagiridzo yekubatanidza minda yakawanda
Panyaya yekuwedzera kuongorora mashandiro enguva refu pasi pekubatanidzwa kwemunyu necarbonation, data rekutanga rinoratidza kuti mwero wecarbonation wekongiri yefiber uri pasi pe0.5 nguva yemutoro wekupedzisira uchiri pasi ne28%.
2. Kubatanidzwa kwekutarisa kwakangwara
Kuisa fiber ye optical uye network ye fiber inoona carbonation, kuteverwa kwe carbonation front panguva chaiyo (kururama ± 0.1 mm), zvichipa rutsigiro rwedata rekuchengetedza kudzivirira.
Basalt faibha inopa mhinduro yematanho akawanda yekudzivirira carbonation yekongiri kuburikidza nekugadzirisa microstructure uye kuwedzera mashandiro macro. Nekuvandudzwa kwehurongwa hwakajairika uye hunyanzvi hwetekinoroji, kushandiswa kwayo kuchawedzerwa kubva kumigwagwa nemabhiriji kusvika kumainjiniya egungwa nedzimwe nzvimbo, zvichisimudzira kugara kwenguva refu kwezvivakwa kusvika kunguva itsva.
