Zotsatira za Basalt Fiber pa Magwiridwe a Permeable Concrete

Basalt fiber, monga buku laling'ono, lochita bwino kwambiri, komanso lothandizira zachilengedwe, limakulitsa kwambiri mawonekedwe amakanika, kulimba, ndi magwiridwe antchito a konkriti yovunda. Pansipa pali kusanthula kwamitundumitundu pazokhudza zake komanso magawo ake okhathamiritsa:

1. Impact pa Mechanical Properties

Kupititsa patsogolo Compressive ndi Flexural Mphamvu

   Basalt fiber kulimbitsa bwino kumawonjezera kukakamiza komanso kusinthasintha kwa konkire yovunda. Kafukufuku akuwonetsa kuti ulusi umapanga maukonde amitundu itatu, kulimbitsa mgwirizano pakati pa zophatikizira ndi phala la simenti pomwe zimalepheretsa kufalikira kwa ming'alu. Mwachitsanzo:

Mphamvu Yopondereza: Ndi ulusi wa 12 mm ndi 24 mm, mphamvu yopondereza imayamba kukula kenako imachepa ndi kuchuluka kwa ulusi. Mlingo woyenera kwambiri ndi 0.1% -0.15% (ndi voliyumu), ndi ulusi wa 24 mm wopeza mphamvu yapamwamba ya 24.3 MPa (pa mlingo wa 0.1%).

Flexural Strength: Utali wa Fiber uli ndi mphamvu yodziwika bwino pamphamvu yosinthika. Mwachitsanzo, ulusi wa 18 mm umawonjezera mphamvu yosunthika ndi 66.44% poyerekeza ndi konkriti wamba chifukwa cha kulumikizana kwapakati pamawonekedwe okhudzana ndi kuchuluka kwa ulusi.

Kulimbitsa Kulimbitsa ndi Ductility

The "mlatho zotsatira" wa Basalt Fibers imathandizira kulimba, kusuntha mitundu yolephera kuchoka ku brittle kupita ku ductile. Kusanthula kwa Microscopic kumawonetsa kuti ulusi umakhazikika m'mafupa a simenti, ndikuletsa kukula kwa crack.

Impact pa Permeability

Kuchepetsa Permeability Coefficient

Kuphatikizika kwa fiber kumatchinga pang'ono pores, kutsitsa kutulutsa. Mwachitsanzo, kuwonjezeka kwa fiber kuchokera ku 0.05% kufika ku 0.2% pang'onopang'ono kumachepetsa kutsekemera kokwanira, komabe kumakwaniritsa zofunikira (mwachitsanzo, permeability> 1 mm / s pa 20% porosity).

Kulinganiza Porosity ndi Fiber Parameters

Ulusi wautali (mwachitsanzo, 12 mm → 24 mm) umawonjezera pang'ono porosity koma umachepetsabe kupenya.

Kuphatikiza ulusi ndi mchere admixtures (mwachitsanzo, ntchentche phulusa) optimizes pore kapangidwe, kuchepetsa permeability kutayika pamene kukhalabe mphamvu.

3. Kupititsa patsogolo Frost Resistance

Nsalu za Basalt kumawonjezera kukhulupirika kwamkati, kumathandizira kwambiri kukana chisanu:

Pambuyo pa maulendo 100 oundana oundana, zitsanzo zowonjezeredwa ndi fiber zimasonyeza kutayika kwakukulu kwa 0.9% ndikusunga 62.5% modulus yosinthika.

Synergy yokhala ndi phulusa la ntchentche (monga 6% fly ash + 6 kg/m³ fibers) imathandiza kupirira chisanu, monga phulusa la ntchentche limayeretsa pore pomwe ulusi umapondereza kusweka kwa chisanu.

4. Ma Parameters Ofunika Kwambiri

Utali Wautali: Ulusi wa 24 mm umalimbikitsidwa kuti ugwirizane ndi mphamvu ndi kupenya, ngakhale ulusi wa 18 mm umapambana mu mphamvu yosinthasintha.

Mlingo wa Mlingo: 0.1%–0.15% ndi voliyumu (kapena 2–6 kg/m³ ndi kulemera). Mlingo wochulukira umayika chiwopsezo cha fiber agglomeration ndikuchepetsa kugwira ntchito.

Zipangizo Zogwirizana: Phulusa la phulusa (6% -15%) kapena fume la silika (6% -9%) limawonjezeranso mphamvu zamakina ndikuchepetsa kutayika.

5. Malangizo a Ntchito

Zowoneka bwino: Zabwino pamanjira oyenda pansi, ma plazas, ndi madera ozizira omwe amafunikira kupenya komanso mphamvu.

Zomangamanga: Gwiritsani ntchito njira yosanganikirana ya "simenti-yokutidwa ndi simenti" kuti mutsimikizire kufalikira kwa ulusi wofanana ndikupewa kugwa.

Mwachidule, basalt CHIKWANGWANI optimizes microstructure ndi makina ntchito permeable konkire, koma mosamalitsa kulamulira mlingo ndi magawo ndondomeko n'kofunika kuti mulingo mphamvu ndi permeability. Kafukufuku wam'tsogolo akuyenera kuyang'ana kwambiri pakusintha kwa fiber surface ndi synergy yazinthu zambiri kuti athane ndi zolephera zomwe zikuchitika.
