Admixture in Construction ke Eng?

Ha ho hahoa, motsoako o bolela ntho e 'ngoe ntle le metsi, li-aggregates, thepa ea samente, kapa likhoele tse kentsoeng ka konkreite, seretse kapa grout ho fetola thepa ea eona kapa ho ntlafatsa ts'ebetso ea eona. Li-admixtures li sebelisetsoa ho fetola konkreite e ncha kapa e thata ka mekhoa e fapaneng, e lumellang taolo e kholo holim'a thepa ea eona le ho ntlafatsa ts'ebetso ea eona, ho tšoarella, matla le litšobotsi tse ling. Mona ke mefuta e meng e tloaelehileng ea metsoako e sebelisoang ho aha:

1. Metsoako e Fokotsang Metsi:

• Li-admixtures tse fokotsang metsi, tse tsejoang hape e le li-plasticizers kapa superplasticizers, ke lisebelisoa tse fokotsang metsi a hlokahalang ho finyella mosebetsi o lakatsehang oa konkreite ntle le ho tela matla kapa ho tšoarella. Ba ntlafatsa phallo le ho sebetsa ha metsoako ea konkreite, ho etsa hore ho be bonolo ho e beha le ho e qeta.

2. Metsoako e Khutlisang morao:

• Li-admixtures tsa morao-rao li sebelisetsoa ho liehisa nako ea ho beha konkreite, seretse kapa grout, e leng se lumellang ho sebetsa nako e telele le nako ea ho behoa. 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:

• Li-admixtures tse potlakisang ke li-admixtures tse potlakisang maemo le ntlafatso ea matla a pele a konkreite, seretse kapa grout, e lumellang tsoelo-pele ea kaho e potlakileng le ho tlosoa pele ha foromo. Hangata li sebelisoa maemong a leholimo a batang kapa ha ho hlokahala matla a potlakileng.

4. Metsoako e Koetlisang Moea:

• Metsoako e kenyang moea ke li-additives tse kenyang lipululana tsa moea tse sa bonahaleng ka har'a konkreite kapa seretse, tse ntlafatsang ho se khone ho hatsela ho qhibiliha, ho qhibiliha 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:

• Li-admixtures tse thibelang kutu ke li-admixtures tse thusang ho 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:

• Li-admixtures tse fokotsang shrinkage ke li-admixtures tse fokotsang ho omisa ho fokotseha ka konkreite, seretse kapa grout, ho fokotsa kotsi ea ho senya le ho ntlafatsa nako e telele ea nako e telele. Li bohlokoa ka ho khetheha libakeng tse kholo tsa konkreite, likarolo tsa konkreite tse kentsoeng pele, le metsoako ea konkreite e sebetsang hantle haholo.

8. Metsoako e thibelang metsi:

• Li-admixtures tse thibelang metsi ke li-admixtures tse ntlafatsang ho se kenelle ha konkreite, seretse kapa grout, ho fokotsa ho kenella ha metsi le ho thibela litaba tse amanang le mongobo tse kang efflorescence, dampness le corrosion. Hangata li sebelisoa meahong ea maemo a tlase, likamoreng tse ka tlase, lithanele le meahong e bolokang metsi.

Ka bokhutšoanyane, li-admixtures li bapala karolo ea bohlokoa ho theknoloji ea sejoale-joale ea konkreite, e lumellang ho fetoha le maemo, ho sebetsa hantle le ts'ebetso mererong ea kaho. Ka ho khetha le ho kenyelletsa metsoako e loketseng metsoakong ea konkreite, lihahi le lienjineri li ka fihlela litlhoko tse ikhethileng tsa moralo, tsa ntlafatsa lits'ebetso tsa kaho, le ho matlafatsa ts'ebetso le botsitso ba meaho ea konkreite.
