Ho matlafatsa Konkreite ka Li-additives

Ho ntlafatsa konkreite ka li-additives ho kenyelletsa ho kenyelletsa metsoako e fapaneng ea lik'hemik'hale le liminerale ka har'a motsoako oa konkreite ho ntlafatsa thepa kapa litšobotsi tse itseng tsa konkreite e thata. Mona ke mefuta e 'maloa ea li-additives tse atisang ho sebelisoa ho ntlafatsa konkreite:

1. Metsoako e Fokotsang Metsi (Plasticizers):
   • Li-admixtures tse fokotsang metsi, tse tsejoang hape e le li-plasticizers kapa superplasticizers, li ntlafatsa ts'ebetso ea ho sebetsa ka ho fokotsa bongata ba metsi a hlokahalang motsoako oa konkreite. Li thusa ho eketsa ho putlama, ho fokotsa karohano, le ho ntlafatsa phallo ea konkreite ntle le ho senya matla.
2. Seta Metsoako e Khutlisang morao:
   • Li-admixtures tsa "set retading" li sebelisetsoa ho liehisa nako ea ho beha konkreite, 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 lipalangoang tse telele le linako tsa ho beoa li hlokahalang.
3. Beha Li-Accelerating Admixtures:
   • Li-accelerating admixtures tsa Seta li sebelisetsoa ho potlakisa nako ea ho beha konkreite, ho fokotsa nako ea kaho le ho etsa hore ho tlosoe le ho phethoa ka potlako. Li molemo maemong a leholimo a batang kapa ha ho hlokahala matla a potlakileng.
4. Metsoako e Kenyelletsang Moea:
   • Li-admixtures tse kenyang moea ho konkreite ho etsa li-bubble tsa moea tse sa bonahaleng ka har'a motsoako, tse ntlafatsang khanyetso ea leqhoa le ho tšoarella. Li matlafatsa ts'ebetso le momahano oa konkreite, haholo-holo maemong a leholimo a mabe.
5. Pozzolans:
   • Lisebelisoa tsa pozzolanic tse kang fly ash, silica fume le slag ke li-additives tsa diminerale tse sebetsanang le calcium hydroxide ka samente ho etsa metsoako e eketsehileng ea samente. Li ntlafatsa matla, ho tšoarella, le ho hanyetsa tlhaselo ea lik'hemik'hale le ho fokotsa mocheso oa hydration.
6. Lifaeba:
   • Li-additives tsa fiber, tse kang tšepe, maiketsetso (polypropylene, nylon), kapa likhoele tsa khalase, li sebelisoa ho matlafatsa matla a tsitsitseng, ho hanyetsa tšusumetso, le ho tiea ha konkreite. Li thusa ho laola ho petsoha le ho ntlafatsa ho tšoarella lits'ebetsong tsa meralo le tseo e seng tsa sebopeho.
7. Metsoako e Fokotsang ho Shrinkage:
   • Li-admixtures tse fokotsang shrinkage li sebelisetsoa ho fokotsa ho fokotseha ha konkreite, ho fokotsa kotsi ea ho senya le ho ntlafatsa ho tšoarella ha nako e telele. Ba sebetsa ka ho fokotsa tsitsipano ea metsi ka holim'a motsoako oa konkreite.
8. Corrosion Inhibitors:
   • Corrosion inhibitors ke li-additives tsa lik'hemik'hale tse sireletsang meaho ea konkreite e matlafalitsoeng ho kutu e bakoang ke li-ion tsa chloride, carbonation kapa lintho tse ling tse mabifi. Ba thusa ho lelefatsa bophelo ba ts'ebeletso ea konkreite libakeng tsa leoatle, indasteri, kapa litsela tse kholo.
9. Lisebelisoa tsa Mebala:
   • Lisebelisoa tsa mebala, joalo ka li-pigment tsa iron oxide kapa lidae tsa maiketsetso, li sebelisoa ho eketsa mmala ho konkreite bakeng sa merero ea mokhabiso kapa botle. Li ntlafatsa boipiletso ba pono ea bokaholimo ba konkreite lits'ebetsong tsa meralo ea meralo le ho bopa naha.

Ka ho kenyelletsa litlatsetso tsena ka har'a metsoako ea konkreite, baenjiniere le borakonteraka ba ka hlophisa thepa ea konkreite ho fihlela litlhoko tse ikhethileng tsa projeke le ho fihlela litšobotsi tse lakatsehang tsa ts'ebetso, joalo ka matla, nako e telele, ts'ebetso le chebahalo.
