Zowonjezera Konkire Zopepuka | Zida Zapamwamba Zotulutsa thovu pa Ma Cellular Concrete
Kuchita bwino kwambiri superplasticizer imakhala ndi mphamvu yobalalika kwambiri pa simenti, zomwe zimatha kusintha kwambiri madzi a simenti osakaniza ndi kugwa kwa konkire, ndipo nthawi yomweyo kuchepetsa kwambiri kumwa madzi ndi bwino kwambiri workability konkire. Komabe, zida zina zochepetsera madzi zamphamvu kwambiri zidzafulumizitsa kugwa kwa simenti. Wothandizira kwambiri wochepetsera madzi sasintha nthawi yoyika konkire. Pamene ndalama ndi zofunika (kulowetsedwa kwa overdose), imakhala ndi kuchedwetsa pang'ono, koma sizimachedwetsa kukula kwamphamvu koyambirira kowumitsidwa konkire.
Ikhoza kuchepetsa kwambiri kumwa madzi ndikuwonjezera kwambiri mphamvu ya konkire pazaka zonse. Pamene ndende ndi zonse, simenti akhoza kupulumutsidwa ndi 10% kapena kuposa.
Chloride ion zili ndi zochepa, ndipo sichichititsa dzimbiri kuzitsulo zachitsulo. Ikhoza kuonjezera impermeability, kukana kuzizira komanso kukana dzimbiri kwa konkriti, ndikusintha kulimba kwa konkriti
The superplasticizer pakali pano pamsika ndi makamaka poly-fusidic asidi kuchepetsa madzi, zomwe zimagwira ntchito yayikulu pakutulutsa thovu simenti kapena matope a konkriti
1. Kupaka mafuta: Hydrophilicity ya polycarboxylic acid superplasticizer ndi yamphamvu kwambiri, kotero kuti adsorption filimu ya polycarboxylic acid superplasticizer pamwamba pa tinthu tating'ono ta simenti imatha kupanga filimu yokhazikika yamadzi osungunuka ndi mamolekyu amadzi.. Filimu yamadzi imakhala ndi mafuta abwino kwambiri, zomwe zimatha kuchepetsa kukana kutsetsereka pakati pa tinthu ta simenti, potero kupititsa patsogolo fluidity ya konkire.
2. Kubalalitsidwa: Pambuyo simenti wothira madzi, chifukwa cha mphamvu yokoka ya maselo a simenti, simenti slurry amapanga flocculation dongosolo, ndicholinga choti 10% ku 30% madzi osakaniza amakulungidwa mu tinthu tating'onoting'ono ta simenti ndipo sangathe kutenga nawo mbali pakuyenda kwaufulu ndi mafuta, potero zimakhudza fluidity wa osakaniza konkire. Pamene polycarboxylic acid superplasticizer iwonjezeredwa, mamolekyu a polycarboxylic acid superplasticizer amatha kutsatiridwa pamwamba pa tinthu tating'ono ta simenti., kotero kuti pamwamba pa particles simenti ali ndi malipiro ofanana (nthawi zambiri zoipa mlandu), zomwe zimapanga electrostatic repulsion effect, The particles simenti amamwazikana wina ndi mzake, mawonekedwe a flocculation akuwonongeka, ndipo gawo lina la madzi okulungidwa limatulutsidwa kuti litenge nawo mbali pakuyenda, potero mogwira kuonjezera fluidity wa osakaniza konkire.
3. Madzi kuchepetsa zotsatira. Pamene konkire yamalonda imasakanizidwa ndi wothandizira kwambiri wochepetsera madzi, chiŵerengero cha madzi-simenti akhoza kuchepetsedwa kwambiri pamene kusunga fluidity. Mlingo wochepetsera madzi wa pulasitiki wa konkire wochita bwino kwambiri ukhoza kufika 10% ku 25%, pamene mtengo wochepetsera madzi wa plasticizer wamba wa konkriti uli 5% ku 15%. Chifukwa cha plasticizer admixture effect makamaka chifukwa cha adsorption ndi kubalalitsidwa kwa wothandizira kuchepetsa madzi ndi konkire yamalonda..
4. Plasticization. Pambuyo kusakanizidwa ndi superplasticizer, konkire malonda akhoza kuonjezera fluidity pamene kusunga madzi simenti chiŵerengero zosasintha. Wothandizira kuchepetsa madzi amatha kuwonjezera kugwa kwa konkire yamalonda yomwe yangosakanikirana ndi 10cm ndikusunga kuchuluka kwa simenti nthawi zonse.. Othandizira kwambiri ochepetsa madzi amatha kukonzekera konkire yamalonda ndi dontho la 25cm.
Pakadali pano, mkulu-mwachangu madzi reducer ndi oyenera minda mafakitale
1 Ndi abwino kwa precast ndi kuponyedwa-m'malo konkriti wolimbitsidwa m'nyumba zosiyanasiyana zamafakitale ndi anthu, kusunga madzi, mayendedwe, doko, masepala, ndi ntchito zina.
2 Oyenera kukweza mphamvu, ultra-high-mphamvu, ndi konkire yapakati-mphamvu, komanso konkire yomwe imafuna mphamvu zatsopano, kukana chisanu pang'ono, ndi kuchuluka kwa fluidity.
3 Precast konkire zigawo zoyenera nthunzi kuchiritsa ndondomeko.
4 Zoyenera kupanga zochepetsera madzi komanso zowonjezera zowonjezera zowonjezera pawiri.
5 Konkire yopepuka ya thovu monga foamed simenti backfill, mapanelo a konkriti opepuka, CLC block CLC njerwa ndi zina.
Cie-China.org ndiye wotsogola wotsogola wa konkriti wa thovu yemwe amapereka thovu la konkriti, superplasticizer,thovu konkire mphamvu zowonjezera kwa wopepuka konkire, Zolemba za CLC. Ngati mukuyang'ana wotulutsa thovu, chonde khalani omasuka Lumikizanani nafe.
