Hoʻonui ka Basalt Fibers i ke kūpaʻa ʻana o ka paʻakai

I. Mechanism o ka anti-carbonation hana: multi-scale synergistic optimization
1. Ka hoʻolālā pore a me ka pale ʻana
   Nā pulu basalt keʻakeʻa i nā māwae ʻeleʻele mua o ka plastik i loko o ke kaʻa (30%-50% ka hoʻemi ʻana i ka laula) a hoʻopaʻa i nā ala hoʻoheheʻe CO₂ ma o ka hāʻawi ʻana i ka mesh ʻekolu. Hiki i nā huahana hydration dense i hana ʻia ma ka fiber-matrix interface ke hōʻemi i ka nui o nā pores pōʻino (> 100 nm) mai 18.6% a i 12.3%, e hōʻemi nui ana i ka permeability.

2. Hoʻololi ʻana i ka wai a me Kemika huikau
Hoʻoikaika ka ʻili o ka fiber i ka CSH gel heterogeneous nucleation, e wikiwiki ana i ka hopena hydration, 28 mau lā hydration degree i hoʻonui ʻia e 8% -12%. Ke hui pū ʻia me nā mea hoʻohui mineral (e laʻa, silica fume), ʻo ka hopena o ka lehu pele i hui pū ʻia me ka hopena fracture fracture-limiting effect i hoʻemi i ka nui o ka porosity e 40%, a ʻo ka hapa o nā pores pōʻino ʻole (

II. ʻO ka hana ʻenehana a me nā pono waiwai
1. Hoʻonui nui ʻia ke ola o ke alanui
Kiʻekiʻe-hana ʻAla Basalt Ua noiʻi ʻia a hoʻomohala ʻia ka asphalt e ke Kulanui ʻo Yangzhou, ua hoʻonui ʻia ke kūʻē ʻana e 20% -40%, ua hoʻonui ʻia ke kūʻē ʻana o ka luhi e 2-8 mau manawa, ua hoʻonui ʻia ka pōʻai mālama mai 3-5 mau makahiki a i 6-8 mau makahiki, ua hoʻemi nui ʻia ka mālama kālā mālama ʻana.

2. Hoʻomaikaʻi i ka hana ʻana o ke kaila i hana hou ʻia
Hōʻike ka noiʻi ʻana i ka hui ʻana o ka ʻāpana aggregate (RAC) me 2 kg/m³ basalt fibers, ua hoʻemi ʻia ka hohonu o ka carbonation e 41% i hoʻohālikelike ʻia me ka pāpaʻi recycled maʻamau, a loaʻa ke kūpaʻa carbonation maikaʻi loa me 50% recycled aggregate substitution rate.

III. Nā ʻano a me nā pilikia e hiki mai ana
1. Ka noiʻi hui ʻana he nui
Pono e ʻimi hou aku i ka hana lōʻihi ma lalo o ka hoʻohui ʻana i ka paʻakai kalapona-chloride, hōʻike ka ʻikepili mua i ka nui o ka carbonation rate o ka fiber concrete ma lalo o 0.5 mau manawa o ka ukana hope loa he 28% ka haʻahaʻa.

2. Hoʻohui naʻauao nānā
Hoʻokomo ʻia o ka fiber optical a me ka fiber network, ka nānā ʻana i ka manawa o ka carbonation mua (pololei ± 0.1 mm), hāʻawi i ke kākoʻo ʻikepili no ka mālama pale.

Basalt fiber hāʻawi i kahi hopena pae-nui no ka pale ʻana i ka carbonation koneki ma o ka microstructure optimization a me ka hoʻonui ʻana i ka hana macro. Me ka hoʻomaikaʻi ʻana i ka ʻōnaehana maʻamau a me ka ʻenehana hou, e hoʻonui ʻia kāna noi mai nā alanui a me nā alahaka i ka ʻenekinia moana a me nā ʻano ʻē aʻe, e hoʻoikaika ana i ka lōʻihi o ka ʻoihana i kahi au hou.
