Li-admixtures ke eng, 'me mefuta e fapaneng ea li-admixtures ke efe?

Li-admixtures ke sehlopha sa lisebelisoa tse kentsoeng konkreite, seretse kapa grout nakong ea ho kopanya ho fetola thepa ea bona kapa ho ntlafatsa ts'ebetso ea bona. Lisebelisoa tsena li fapane le lisebelisoa tse ka sehloohong tsa konkreite (samente, li-aggregates, metsi) 'me li sebelisoa ka bongata bo fokolang ho finyella liphello tse lakatsehang tse itseng. Li-admixtures li ka fetola thepa e fapaneng ea konkreite, ho kenyelletsa ho sebetsa, ho beha nako, matla, ho tšoarella, le ho hanyetsa maemo a tikoloho. Ba fana ka maemo a feto-fetohang moralong oa motsoako oa konkreite, ho lumella lienjineri le lihahi ho rala libopeho tsa konkreite ho fihlela litlhoko tse ikhethang tsa projeke. Mona ke mefuta e fapaneng ea li-admixtures tse atisang ho sebelisoa ha ho etsoa:

1. Metsoako e Fokotsang Metsi (Li-Plasticizer kapa Superplasticizers):

• Li-admixtures tse fokotsang metsi ke li-additives tse fokotsang metsi a hlokahalang bakeng sa ho theoha ha konkreite ntle le ho senya ts'ebetso ea eona. Li ntlafatsa ho phalla le ho sebetsa ha metsoako ea konkreite, ho lumella ho behoa habonolo le ho kopana. Hangata li-plasticizers li sebelisoa ka konkreite ka linako tse tloaelehileng tsa ho beha, ha li-superplasticizers li sebelisoa ka konkreite e hlokang linako tse atolositsoeng tsa ho beha.

2. Li-Admixtures tsa morao-rao:

• Li-admixtures tse khutlisang morao li liehisa nako ea ho beha konkreite, seretse kapa grout, e leng se lumellang ho sebetsa nako e telele le nako ea ho beoa. Li bohlokoa ka ho khetheha maemong a leholimo a chesang kapa bakeng sa merero e meholo moo ho lebelletsoeng tieho ea lipalangoang, ho beoa kapa ho phetheloa.

3. Ho Potlakisa Metsoako:

• Ho potlakisa metsoako e eketsa sekhahla sa ho seta le nts'etsopele ea matla a konkreite, seretse, kapa grout, e leng se lumellang tsoelo-pele ea kaho e potlakileng le ho tlosoa ha foromo ea pele. Hangata li sebelisoa maemong a leholimo a batang kapa ha ho hlokahala matla a potlakileng.

4. Metsoako e Koetlisang Moea:

• Metsoako e kenyang moea e hlahisa lipululana tsa moea tse sa bonahaleng ka har'a konkreite kapa seretse, e ntlafatsang ho hanyetsa ha eona lipotolohong tsa ho qhibiliha ha leqhoa, ho khephoha le ho khojoa. Li matlafatsa ts'ebetso le ho tšoarella ha konkreite maemong a leholimo a mabe le ho fokotsa kotsi ea ho senyeha ho tloha ho fetoha ha mocheso.

5. Li-Admixtures tse fokotsang Moea:

• Li-admixtures tse thibelang moea tse thibelang moea li kopanya thepa ea ho lieha le ho kenya moea, ho liehisa nako ea ho beha konkreite ha e ntse e kenya moea ho ntlafatsa khanyetso ea eona ea leqhoa. Hangata li sebelisoa maemong a leholimo a batang kapa bakeng sa konkreite e pepesehetseng maqhubu a leqhoa le ho qhibiliha.

6. Corrosion-Inhibiting Admixtures:

• Metsoako e thibelang kutu e sireletsa tšepe e kentsoeng ka konkreite hore e se ke ea bola e bakoang ke ho pepesehela mongobo, li-chloride kapa lintho tse ling tse mabifi. Ba eketsa bophelo ba tšebeletso ea mehaho ea konkreite le ho fokotsa litšenyehelo tsa tlhokomelo le ho lokisa.

7. Metsoako e fokotsang ho fokotseha:

• Metsoako e fokotsang shrinkage e fokotsa ho omella ka konkreite, ho fokotsa kotsi ea ho phatloha le ho ntlafatsa ho tšoarella ha nako e telele. Li na le thuso libakeng tse kholo tsa konkreite, likarolo tsa precast, le metsoako ea konkreite e sebetsang hantle.

8. Metsoako e thibelang metsi:

• Metsoako e thibelang metsi e ntlafatsa ho se kenelle ha konkreite, ho fokotsa ho kenella ha metsi le ho thibela litaba tse amanang le mongobo joalo ka efflorescence, mongobo le kutu. Hangata li sebelisoa meahong ea maemo a tlase, likamoreng tse ka tlase, lithanele le meahong e bolokang metsi.

9. Metsoako ea Mebala:

• Li-admixtures tsa mebala li eketsoa ka konkreite ho fana ka mebala kapa ho fihlela litlamorao tse khabisitsoeng. Li tla ka mefuta e fapaneng, ho kenyeletsoa li-pigments, matheba, lidae le li-sealers tse tint, tse lumellang hore ho be le maemo a ikhethileng a konkreite ho tsamaisana le litlhoko tsa moralo.

10. Rheology-Modifying Admixtures:

• Metsoako e fetolang Rheology e fetola phallo le thepa ea rheological ea konkreite, seretse kapa grout ho ntlafatsa ts'ebetso, ho pompa, kapa taolo ea viscosity. Hangata li sebelisoa ho kopanya konkreite, li-shotcrete le metsoako ea konkreite e sebetsang hantle haholo.

Tsena ke tse ling tsa mefuta ea mantlha ea li-admixtures tse sebelisoang kahong, e 'ngoe le e' ngoe e fana ka melemo le lits'ebetso tse ikhethileng bakeng sa ho ntlafatsa ts'ebetso ea konkreite le ho fihlela litlhoko tsa projeke. Ho bohlokoa ho khetha le ho kenyelletsa li-admixtures tse nepahetseng ho ipapisitsoe le lintlha tsa projeke, maemo a tikoloho le mekhoa ea ts'ebetso.
