Zowonjezera Konkire Zopepuka | Zida Zapamwamba Zotulutsa thovu pa Ma Cellular Concrete
konkire yopepuka ya thovu (LFC) kapena aircrete ndi mtundu wa konkire yopepuka yopepuka yomwe ilibe coarse aggregate ndipo imapangidwa ndi kusakaniza madzi., simenti ndi thovu. Imakhala ndi kulemera kocheperako, kugwirira ntchito kwakukulu ndi katundu wapamwamba wotetezera koma mphamvu zochepa kusiyana ndi konkire yamphamvu. Itha kugwiritsidwa ntchito ponyamula katundu wopangidwa ndi makonzedwe oyenera osakaniza ndi njira zopangira.
Pepalali ndikuwunika mwatsatanetsatane zotsatira za nanosilica (NS) pa compressive mphamvu, kuyanika kuchepa, Thermal conductivity ndi sorption wa Ultra-konkire yopepuka ya thovus (Zithunzi za ULFC) ndi kachulukidwe otsika kuposa 350 kg/m3. Zoyesererazo zidachitika mu a 50 L Eirich chosakanizira pogwiritsa ntchito kukameta ubweya wa ubweya mpaka 1000 rpm pa. Zida zabwino zinali zowuma zosakaniza 30 s kenako madzi, superplasticizer ndi stabilizer adawonjezeredwa kuti apange slurry ya simenti. Kenako mpweya unkabayidwa kuti utulutse thovulo.
Zotsatira za kafukufukuyu zikuwonetsa kuti kuwonjezeredwa kwa NS kwasintha mawonekedwe atsopano komanso owuma a ma ULFC, makamaka mphamvu yake yopondereza. Mwambiri, mawonekedwe olimba a zitsanzo za ULFC okhala ndi NS anali ndi makoma okhuthala, zomwe zidathandizira kulimba kwake kopitilira muyeso.
Zinapezekanso kuti hydration process ya ULFCs ndi NS imachitika mwachangu kuposa momwe zimakhalira ndi SF chifukwa cha kukula kwake kakang'ono.. NS yophatikizidwa mu ULFCs imasinthanso mawonekedwe awo a pore ndikuwonjezera kulumikizana pakati pa voids.. Izi zimachepetsa kwambiri kuyanika kwa ULFC.
