ʻO ka hopena o ka fiber basalt i ka hana ʻana o ka palaki permeable
Basalt fiber, ma ke 'ano he mea anoano hou, hana ki'eki'e, a me ka ho'onanea 'ana i ka kaiaola, ho'onui nui i ka waiwai mechanical, ka lō'ihi, a me ka hana o ke koneki permeable. Aia ma lalo iho kahi loiloi multidimensional o kāna mau hopena a me nā ʻāpana hoʻohālikelike:
- Ka hopena ma nā waiwai Mechanical
Hoʻomaikaʻi i ka ikaika Compressive a Flexural
Basalt fiber hoʻoikaika maikaʻi ka hoʻoikaika ʻana i ka ikaika compressive a me ka flexural o ka permeable concrete. Hōʻike nā haʻawina e hoʻokumu ana nā fibers i ʻekolu-dimensional network structure, e hoʻoikaika ana i ka hoʻopaʻa ʻana ma waena o nā aggregates a me ka paʻi sima ʻoiai ke keʻakeʻa nei i ka hoʻolaha ʻana. ʻo kahi laʻana:
Ka ikaika compressive: Me ka 12 mm a me 24 mm fibers, piʻi mua ka ikaika compressive a laila e emi iho me ka ʻoi aku ka nui o ka fiber. ʻO 0.1%-0.15% ka mea kūpono loa (ma ka nui), me nā fibers 24 mm e loaʻa ana ka ikaika compressive peak o 24.3 MPa (ma 0.1% dosage).
ʻOi aku ka maikaʻi o ka lōʻihi o ka fiber i ka ikaika flexural. No ka laʻana, hoʻonui ka 18 mm fibers i ka ikaika flexural e 66.44% i hoʻohālikelike ʻia me ka paʻa paʻa ma muli o ka hoʻopili ʻana o ka interfacial mai ka hoʻonui ʻia ʻana o ka pilina fiber-aggregate.
Hoʻonui i ka paʻakikī a me ka Ductility
ʻO ka "pilikia pili" o ʻAla Basalts hoʻomaikaʻi i ka paʻakikī, hoʻololi i nā ʻano hana hāʻule mai ka brittle a ductile. Hōʻike ka hōʻike ʻana i ka microscopic e hoʻopaʻa ʻia ke ʻano iwi i loko o ka matrix sima, me ka pale pono ʻana i ka ulu ʻana o ka māwae.
Ka hopena ma ka Permeability
Hoʻemi ʻia ʻo Permeability Coefficient
Hoʻopili ʻia ka fiber i nā pores, hoʻohaʻahaʻa i ka permeability. No ka laʻana, ʻo ka hoʻonui ʻana i ka fiber mai 0.05% a hiki i ka 0.2% e hoʻemi mālie i ka coefficient permeability, akā e hoʻokō mau ana ia i nā kikoʻī (e laʻa, permeability >1 mm/s ma 20% porosity).
Ke kaulike i ka Porosity a me ka Fiber Parameter
ʻO nā fiber lōʻihi (e laʻa, 12 mm → 24 mm) hoʻonui iki i ka porosity akā hoʻemi mau i ka permeability.
ʻO ka hoʻohui ʻana i nā fiber me nā mea hoʻohui mineral (e laʻa, lele lehu) e hoʻomaikaʻi i ke ʻano o ka pore, e hōʻemi ana i ka nalowale o ka permeability me ka mālama ʻana i ka ikaika.
- Hoʻomaikaʻi i ka pale hau
Nā pulu basalt hoʻonui i ka paʻa o loko, hoʻonui nui i ka pale hau:
Ma hope o 100 mau pōʻai maloʻo maloʻo, hōʻike nā mea hoʻohālike i hoʻoikaika ʻia i ka fiber i ka nui o ka pohō ma lalo o 0.9% a mālama ʻia 62.5% pili i ka modulus elastic elastic.
ʻO ka hui pū ʻana me ka lehu lele (e laʻa, 6% lehu lele + 6 kg/m³ fibers) loaʻa i ka pale hau maikaʻi loa, ʻoiai ʻo ka lehu lele e hoʻomaʻemaʻe i ke ʻano pore aʻo nā fibers e hoʻopaʻa i ka haki ʻana i ka hau.
- Nā Kūlana Kūlana Nui
ʻO ka lōʻihi o ka fiber: 24 mm ka manaʻo no ke kaulike ʻana i ka ikaika a me ka permeability, ʻoiai ʻo 18 mm ka nui o nā fibers i ka ikaika flexural.
Ka Laulā: 0.1%–0.15% ma ka leo (ai ole 2–6 kg/m³ ma ka nuipa). ʻO ka nui o ka dosage e pilikia ai ka hoʻohui ʻana o ka fiber a hoʻemi i ka hana.
Mea Hana Hana: Lehu lele (6%–15%) a i ʻole silica fume (6%–9%) e hoʻomaikaʻi hou aku i nā waiwai mīkini a hoʻēmi i ka nalowale o ka permeability.
- Nā Manaʻo Noi
Nā hiʻohiʻona: He kūpono no nā ala hele wāwae, nā plaza, a me nā wahi anuanu e koi ana i ka permeability a me ka ikaika.
Kūkulu: E hoʻohana i ke ʻano hui ʻana o "cement-coated aggregate" e hōʻoia i ka hoʻopuehu ʻana o ka fiber a pale i ka puʻupuʻu.
I ka hōʻuluʻulu ʻana, hoʻomaikaʻi ka basalt fiber i ka microstructure a me ka hana mechanical o ka permeable concrete, akā ʻo ka mālama paʻa ʻana i ka dosage a me nā ʻāpana kaʻina hana koʻikoʻi e kaulike i ka ikaika a me ka permeability. Pono ka noiʻi e hiki mai ana i ka hoʻololi ʻana o ka fiber surface a me ka synergy multi-material e lanakila ai i nā palena hana o kēia manawa.
