Li-additives tsa Konkreite tse bobebe | Li-Agents tse Foaming tse Phahameng ka ho Fetisisa bakeng sa Konkreite ea Cellular
Tšebeliso ea konkreite e bobebe (LEHLOHONOLO) kahong e ntse e eketseha ka lebaka la melemo ea eona e mengata ho feta konkreite e tloaelehileng ea boima. Molemo o ka sehloohong ke hore o ka fokotsa mojaro o shoeleng oa mohaho ka 20% - 80%. This will save on construction cost and increase the speed of a project. It can be used to construct floors, mabota, li-piers, deck slabs, bridges and precast structures. It is suitable for low-rise and high-rise buildings and can be easily transported from the batch plant to the construction site.
It is cheaper to make than regular concrete because it uses less cement. E boetse e bobebe, which makes it easier to lift and place. It is also more environmentally friendly because it uses waste materials such as fly ash, slag and pumice instead of natural sand.
Lightweight concrete can be made using different methods, ho kenyelletsa ho nkela li-aggregates tse tloaelehileng tsa liminerale ka likarolo tsa cellular porous. Sena se etsa hore ho be le likheo tsa mahe a linotši ka har'a konkreite, 'me li etsa hore ho be le khekhe ea linotši, e tsejoang joalo ka konkreite e nang le moea o motlakase. Mokhoa o mong o kenyelletsa ho tlohela lehlabathe ho tsoa motswakong ho etsa konkreite e se nang litefello.
Mefuta e meng ea konkreite e bobebe e kenyelletsa konkreite e phophomang le konkreite ea aerated ea autoclaved, tseo ka bobedi di hlahisoang ka ho kenya moya motswako wa thepa e tala le samente. Tsena li tšoana haholo le konkreite e tloaelehileng, empa ka ho eketsoa ha li-bubble tsa moea. Li ka fapana ka bongata ho tloha ho 1200 Kg/m3 – 1800 Kg/m3.
Konkreite e bobebe e entsoe ka lisebelisoa tse fapaneng tse nchafalitsoeng le tse sa sebelisoang hape, joalo ka styrofoam, corral, letsopa, shale e atolositsoeng, mapolanka, pumice, likhetla tsa oli ea palema le sekoti sa poone. Ho sebelisoa hape ha lisebelisoa tsena ho thusa ho eketsa tšebeliso ea lisebelisoa tse teng le ho fokotsa tšebeliso ea matla. Li-concrete tsena tse bobebe li boetse li na le conductivity e tlaase ea mocheso, e lumellang ho fokotsa tšebeliso ea matla bakeng sa ho futhumatsa le ho pholisa mohaho.
