Metsoako bakeng sa Konkreite

Li-admixtures bakeng sa konkreite ke lisebelisoa tse khethehileng tse kenyelletsoeng motsoako oa konkreite nakong ea ho kopanya kapa ho kopanya ho fetola thepa ea eona kapa ho ntlafatsa tshebetso ea eona. Li-admixtures tsena li ka ntlafatsa likarolo tse fapaneng tsa konkreite, ho kenyelletsa ho sebetsa, matla, ho tšoarella, nako ea ho beha, le ho hanyetsa lik'hemik'hale kapa maemo a tikoloho. Mona ke mefuta e meng e tloaelehileng ea li-admixtures tsa konkreite:

1. Metsoako e Fokotsang Metsi:

• Li-admixtures tse fokotsang metsi, tse tsejoang hape e le li-plasticizers kapa li-superplasticizers, li sebelisetsoa ho fokotsa metsi a hlokahalang motsoako oa konkreite ha o ntse o boloka ts'ebetso.
• Ba ntlafatsa ho phalla le ho sebetsa ha konkreite, ho etsa hore ho be bonolo ho beha le ho qeta.
• Li-superplasticizers li ka hlalosoa e le maemo a holimo kapa a bohareng ho latela bokhoni ba tsona ba ho fokotsa metsi le ho eketsa ho putlama.

2. Seta li-Admixtures tse khutlisang morao:

• Li-admixtures tsa "set retading" li sebelisetsoa ho liehisa nako ea ho beha konkreite, e leng ho lumellang hore ho behoe nako e eketsehileng le ho qeta nako.
• Li molemo maemong a leholimo a chesang kapa ha li tsamaisa konkreite maetong a malelele.
• Metsoako ena e ka boela ea thusa ho thibela manonyeletso a batang le ho ntlafatsa maqhama pakeng tsa ho tšela konkreite ka ho latellana.

3. Ho Potlakisa Metsoako:

• Li-admixtures tse potlakileng li eketsoa ho konkreite ho potlakisa maemo le nts'etsopele ea matla a pele.
• Li na le thuso maemong a leholimo a batang kapa ha ho hlokahala linako tsa kaho tse potlakileng.
• Calcium chloride ke motsoako o potlakileng oa ho potlakisa, leha ts'ebeliso ea eona e ka lebisa ho bola ha tšepe e matlafatsang le efflorescence.

4. Metsoako e Koetlisang Moea:

• Li-admixtures tse kenyang moea li sebelisoa ho hlahisa lipululana tsa moea tse sa bonahaleng ka har'a motsoako oa konkreite.
• Li-bubble tsena tsa moea li ntlafatsa ho tšoarella ha konkreite ka ho fana ka khanyetso ho lipotoloho tsa ho qhibiliha, ho fokotsa mali le ho arola, le ho ntlafatsa ts'ebetso.
• Metsoako e kenyang moea hangata e sebelisoa libakeng tse batang le bakeng sa konkreite e pepesehileng matsoai a de-icing.

5. Metsoako e fokotsang nako le e fokotsang metsi:

• Li-admixtures tsena li kopanya thepa ea li-admixtures tse fokotsang metsi le tse fokotsang metsi.
• Ba liehisa nako ea ho beha konkreite ha ka nako e le 'ngoe ba ntlafatsa ts'ebetso le ho fokotsa metsi.
• Metsoako e fokotsang metsi le e fokotsang metsi hangata e sebelisoa maemong a leholimo a chesang ho thibela boemo bo potlakileng le tahlehelo ea ho putlama.

6. Corrosion-Inhibiting Admixtures:

• Li-admixtures tse thibelang li-corrosion li kenngoa ka konkreite ho sireletsa matla a tšepe a kentsoeng ho tloha ho senya.
• Ba theha lera le sireletsang holim'a matlafatso, ho thibela ho kenella ha chloride le lintho tse ling tse senyang.
• Metsoako ena e bohlokoa haholo tikolohong ea leoatle kapa meahong e pepesehileng matsoai a de-icing.

7. Metsoako e fokotsang ho fokotseha:

• Metsoako e fokotsang shrinkage e sebelisoa ho fokotsa ho honyela ho omisa le ho phatloha ha konkreite.
• Li sebetsa ka ho fokotsa tsitsipano ea metsi a pore, e lumellang ho omisa ka mokhoa o ts'oanang le ho fokotsa ho fokotseha.
• Metsoako ena e na le molemo libakeng tse kholo tsa konkreite, likarolo tsa konkreite ea precast, le metsoako ea konkreite e sebetsang hantle.

Li-admixtures li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le ho tšoarella ha konkreite lits'ebetsong tse fapaneng. Ka ho khetha ka hloko le ho kenyelletsa metsoako e loketseng motsoakong oa konkreite, baenjiniere le borakonteraka ba ka fihlela thepa e lakatsehang joalo ka ts'ebetso e ntlafalitsoeng, matla, nako e telele le ho hanyetsa maemo a mabe a tikoloho. Ho bohlokoa ho latela likhothaletso tsa moetsi le litataiso tsa litekanyetso ha u sebelisa li-admixtures ho netefatsa ts'ebetso e nepahetseng le ho lumellana le motsoako oa konkreite.
