Zotsatira za Ulusi wa Basalt pa Kugwira Ntchito kwa Konkire Yolowa Madzi
Ulusi wa basalt, monga chinthu chatsopano chosapangidwa ndi zinthu zachilengedwe, chogwira ntchito bwino, komanso chosamalira chilengedwe, chimawonjezera kwambiri mphamvu zamakina, kulimba, komanso magwiridwe antchito a konkriti yolowa madzi. Pansipa pali kusanthula kwamitundu yambiri kwa zotsatira zake ndi magawo owongolera:
- Zotsatira pa Katundu wa Makina
Mphamvu Yolimbitsa ndi Yosinthasintha Yolimbitsa
Ulusi wa basalt Kulimbitsa konkire kumapangitsa kuti konkire yolowa m'madzi ikhale yolimba komanso yopindika. Kafukufuku akusonyeza kuti ulusi umapanga kapangidwe ka netiweki ya mbali zitatu, kulimbitsa mgwirizano pakati pa ma aggregates ndi simenti phala pomwe kumaletsa kufalikira kwa ming'alu. Mwachitsanzo:
Mphamvu Yokakamiza: Ndi ulusi wa 12 mm ndi 24 mm, mphamvu yokakamiza imawonjezeka poyamba kenako imachepa ndi ulusi wambiri. Mlingo woyenera ndi 0.1%–0.15% (ndi voliyumu), ndipo ulusi wa 24 mm umakhala ndi mphamvu yokakamiza ya 24.3 MPa (pa mlingo wa 0.1%).
Mphamvu Yopindika: Kutalika kwa ulusi kumakhudza kwambiri mphamvu yopindika. Mwachitsanzo, ulusi wa 18 mm umawonjezera mphamvu yopindika ndi 66.44% poyerekeza ndi konkriti wamba chifukwa cha kulumikizana kwabwino pakati pa ulusi ndi ulusi.
Kulimba Kwambiri ndi Kusinthasintha
"Zotsatira zolumikizirana" za Ulusi wa BasaltKusanthula kwa microscopic kumasonyeza kuti ulusi umalimbitsa kapangidwe ka mafupa mkati mwa simenti, zomwe zimathandiza kuletsa kukula kwa ming'alu.
Zotsatira pa Kutha kwa Kukhazikika
Kuchepetsa Kutha kwa Kutha kwa Kutha
Kuphatikizidwa kwa ulusi kumatseka pang'ono ma pores, zomwe zimachepetsa kulowerera kwa mpweya. Mwachitsanzo, kuwonjezera kuchuluka kwa ulusi kuchokera pa 0.05% mpaka 0.2% pang'onopang'ono kumachepetsa kulowerera kwa mpweya, komabe kumakwaniritsabe zofunikira (monga kulowerera >1 mm/s pa 20% porosity).
Kulinganiza Ma Porosity ndi Ma Fiber Parameters
Ulusi wautali (monga 12 mm → 24 mm) umawonjezera pang'ono ma porosity koma umachepetsabe kulowa kwa madzi.
Kuphatikiza ulusi ndi zinthu zina za mchere (monga phulusa la ntchentche) kumakonza kapangidwe ka ma pore, kuchepetsa kutayika kwa madzi pamene kuli kolimba.
- Kulimbana ndi Chipale Chofewa Kwambiri
Ulusi wa Basalt kulimbitsa umphumphu wa kapangidwe ka mkati, zomwe zimathandizira kwambiri kukana chisanu:
Pambuyo pa nthawi 100 zozizira ndi kusungunuka, zitsanzo zolimbikitsidwa ndi ulusi zimawonetsa kutayika kwakukulu mpaka 0.9% ndipo zimasunga 62.5% relative dynamic elastic modulus.
Kugwirizana ndi phulusa la ntchentche (monga phulusa la ntchentche 6% + ulusi wa 6 kg/m³) kumathandizira kukana chisanu bwino, chifukwa phulusa la ntchentche limakonza kapangidwe ka mabowo pomwe ulusi umaletsa kusweka kwa kuzizira ndi kusungunuka.
- Magawo Othandizira Kukonza Makiyi
Utali wa Ulusi: Ulusi wa 24 mm umalimbikitsidwa kuti ukhale wolimba komanso wopepuka, ngakhale ulusi wa 18 mm umakhala wamphamvu kwambiri.
Mlingo Wochuluka: 0.1%–0.15% ndi voliyumu (kapena 2–6 kg/m³ ndi kulemera). Mlingo wochuluka ungayambitse kusonkhana kwa ulusi ndi kuchepa kwa ntchito.
Zipangizo Zogwirizana: Phulusa louluka (6%–15%) kapena utsi wa silica (6%–9%) zimawonjezera mphamvu zamakina ndikuchepetsa kutayika kwa madzi.
- Malangizo Ogwiritsira Ntchito
Zochitika: Zabwino kwambiri poyenda pansi, malo ochitira masewera olimbitsa thupi, ndi malo ozizira omwe amafunika kulowa mosavuta komanso mphamvu.
Ntchito yomangaGwiritsani ntchito njira yosakaniza ya "aggregate yophimbidwa ndi simenti" kuti muwonetsetse kuti ulusi ufalikira mofanana komanso kupewa kusonkhana.
Mwachidule, ulusi wa basalt umawongolera kapangidwe kake kakang'ono ndi magwiridwe antchito a makina a konkriti wolowa madzi, koma kuwongolera mosamalitsa kuchuluka kwa dothi ndi magawo a njira ndikofunikira kwambiri kuti pakhale mphamvu ndi kulowerera bwino kwa nthaka. Kafukufuku wamtsogolo ayenera kuyang'ana kwambiri pakusintha kwa pamwamba pa ulusi ndi mgwirizano wazinthu zambiri kuti athetse zofooka zomwe zilipo pakali pano.
