Ho Etsahala'ng Haeba Konkreite e Le Metsi Haholo?

1. Selelekela

Konkreiteke motheo oa kaho ea sejoale-joale. Ho tloha litseleng le marokhong ho ea ho matlo le mehaho e meholohali, ho tšoarella ha eona le ho feto-fetoha ha maemo ho etsa hore e be thepa ea kaho e ratoang lefatšeng ka bophara. Leha ho le joalo, ts'ebetso ea konkreite e itšetlehile haholo ka likarolo tsa eona tsa motsoako. E 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa ke karo-karolelano ea metsi-to-samente (w/c). Le hoja metsi a le bohlokoa bakeng sa ho phalla ha metsi le ho sebetsa hantle, a mangata haholo a ka baka mathata a mangata.KimaCell® e hlahloba se etsahalang ha konkreite e kolobile haholo, e hlahloba litlamorao ho matla, ho tšoarella, botle le ts'ebetso ea nako e telele.

2. Karolo ea Metsi ka Konkreite

Metsi a konkreite a sebeletsa merero e mengata:

• E qala karabelo ea lik'hemik'hale ka samente (hydration)
• E matlafatsa bokhoni ba ho sebetsa bakeng sa ho beha le ho qeta
• E thusa ho kopanya le ho kopanya

Leha ho le joalo, ke hoo e ka bang 25-30% feela ea metsi ka boima ba samente e hlokahalang bakeng sa hydration e feletseng. Metsi afe kapa afe a tlatselletsang a eketsa karo-karolelano ea w/c mme a hlapolla motsoako, a beha sehlahisoa sa ho qetela kotsing.

3. Ho utloisisa Karolelano ea Metsi ho Samente

The w/c ratio ke karo-karolelano ea boima ba metsi ho boima basamente e sebedisoang motswakong wa konkreite. Karo-karolelano e tlase e lebisa matla a phahameng le ho tšoarella empa e fokotsehile ho sebetsa. Karolelano e phahameng e ntlafatsa ts'ebetso empa e fokotsa matla le ho eketsa porosity. Likarolo tse loketseng hangata li tloha ho 0.4 ho isa ho 0.6 bakeng sa lits'ebetso tse ngata tsa meralo.

4. Matšoao a Konkreite e Metsi Ho Feta

Ha konkreite e kolobile haholo, matšoao a mangata a hlaha:

• Ho tsoa mali ho feteletseng (metsi a nyolohelang holimo)
• Karohano ea lihlopha lepeista ea samente
• Nako ea ho beha butle
• Litefiso tsa ho theoha ho feta tse boletsoeng
• Bokahohle bo botala kapa bo lerole

5. Liphello ho Matla a Compressive

Matla a khatello ke thepa ea bohlokoa ka ho fetisisa ea konkreite lits'ebetsong tsa meralo. Metsi a feteletseng a lebisa ho eketseha ha capillary porosity, e fokolisang matrix. Lipatlisiso li bontša hore ho eketsa tekanyo ea w / c ho tloha ho 0.4 ho ea ho 0.6 ho ka fokotsa matla a khatello ho fihlela ho 30%. Tahlehelo ena e sitisa matla a ho jara 'me e ka baka ho hloleha ha sebopeho pele ho nako.

6. Tšusumetso ho Durability

Ho tšoarella ho bolela bokhoni ba konkreite ba ho mamella maemo a tikoloho joalo ka potoloho ea leqhoa, ho pepesehela lik'hemik'hale, le ho abrasion. Metsi a mangata haholo a eketsa ho kenella, ho etsa hore konkreite e hlaselehe habonolo:

• Ho kenella ka chloride le ho senya tšepe e matlafatsang
• Tlhaselo ea sulfate le karabelo ea alkali-silika
• Ho kenella ha mongobo ho lebisang tshenyong ya mohatsela

7. Ho petsoha le ho Honyela

Metsi a phahameng a baka ho fokotseha ho hoholo ha ho omisa ha motsoako o lahleheloa ke metsi a mangata. Sena se lebisa ho:

• Ho nyenyefala ha polasetiki
• Ho omisa mapatso a ho honyela
• Crazing (mapetso a matle a holim'a metsi)

Mapetsong ana a fokotsa botšepehi le botle ba konkreite mme e ka fetoha litsela tsa metsi le lik'hemik'hale.

8. Mefokolo ea Sefahleho

Metsoako e nang le metsi hangata e baka ho senyeha ha bokaholimo ka lebaka la:

• Ho tsoa mali le ho laitance
• Ho roala lerōle (karolo e fokolang ea bokaholimo e tloaetseng ho roala)
• Ho se mamelle hantle ha li-coatings le liphetho

Mefokolo e joalo ha se botle bo botle feela empa e boetse e sebetsa, haholo-holo fulurung le mapatlelong.

9. Ho Bea Nako le Ho Fokotsa Mathata

Ho fetelletsekonkreite e metsiho nka nako e telele ho beha. Nako e atolositsoeng ea litlhophiso e thatafatsa kemiso ea kaho mme e ka baka ho se phekolehe ho lekaneng. Phekolo e sa lokang e ka lebisa ho:

• hydration e sa fellang
• Kholiso e fokolang ea matla
• Ho petsoha bokahodimo

10. Karohano le Mahe a linotsi

Metsi a feteletseng a ka etsa hore li-aggregate tse boima li theohe ha sekontiri se bobebe sa samente se phahama, e leng se lebisang ho khethollo. Sena se baka:

• Ho pata mahe a linotsi (li-voids ka har'a konkreite)
• Kabo e sa lekaneng ea thepa
• Botšepehi bo fokotsehileng ba sebopeho

11. Matšoenyeho a Ts'ebetso ea Nako e Telele

Konkreite e nang le metsi a mangata haholo e ka feta litekong tsa pele empa e na le bothata ba:

• Nako ea bophelo e fokotsehile
• Ho qala ho senyeha hoa pele
• Litšenyehelo tse eketsehileng tsa tlhokomelo

Litaba tsena li atisa ho hlaha lilemo hamorao, ho etsa hore taolo ea pele ea motsoako e be ea bohlokoa.

12. Kotsi ea Tšireletseho le Sebopeho

Litho tsa sebopeho tse entsoeng ka konkreite e fokolang li baka likotsi tse tebileng:

• Likholomo le maballo li kanna tsa se ke tsa tšehetsa meroalo ea moralo
• Libaka tse petsohileng kapa tse petsohileng li ka lematsa baahi
• Potlako ea kutu ea matlafatso e ka lebisa ho putlama

13. Tšusumetso ea Moruo

Ho sebelisa metsi a mangata haholo motsoakong ho ka fokotsa litšenyehelo tsa nakoana ka ho ntlafatsa ts'ebetso, empa litlamorao tsa nako e telele tsa moruo li kenyelletsa:

• Litšenyehelo tsa ho lokisa le ho lokisa
• Likoloto tsa molao
• Bophelo ba tšebeletso bo fokotsehileng

14. Mekhoa e Molemo ka ho Fetisisa ea ho Qoba Konkreite e Metsi Ho Feta

Ho thibela metsi a feteletseng:

• Sebelisalisebelisoa tsa metsi or li-plasticizers
• Sebelisa li-batching tse laoloang le ho kopanya
• Etsa liteko tsa ho putlama 'me u fetole maemo a metsi ka nepo
• Ruta basebetsi ba sebakeng sa marang-rang mabapi le motsoako o tsitsitseng

Metsi ke sabole e sehang ka nģa tse peli ka konkreite. Le hoja e le ea bohlokoa bakeng sa ho phalla le ho sebetsa, metsi a feteletseng a senya hoo e batlang e le thepa e 'ngoe le e' ngoe e lakatsehang ea konkreite e thata. Ho tloha ho matla a fokotsehileng le ho tšoarella ho ea ho ho phunyeha ho eketsehileng le ho senyeha ha bokaholimo, likotsi tsa konkreite e metsi haholo li bohlokoa. Ka ho utloisisa litlamorao le ho sebelisa moralo o nepahetseng oa motsoako le taolo ea boleng, likotsi tsena li ka fokotsoa, ​​ho netefatsa meaho ea konkreite e tšoarellang nako e telele le e bolokehileng.

At Kima Chemical, re fana ka boleng bo phahamengli-additives tsa boemo ba kahoho kenyelletsa:

HPMC(Hydroxypropyl Methylcellulose)- bakeng sa ho boloka metsi hantle le ho sebetsa hantle

MHEC(Methyl Hydroxyethyl Cellulose) -e loketse bakeng sa viscosity e tsitsitseng le ts'ebeliso e boreleli

RDP(Redispersible Polymer Powder)- bakeng sa matla a ntlafetseng a tlamahano, ho tenyetseha, le ho hanyetsa crack
Hore na o etsa konkreite bakeng sa liphetho tse boreleli, maemo a mahoashe, kapa lisebelisoa tse tenyetsehang lits'ebetsong tsa sejoale-joale tsa insulation,Kima Chemicalli-additives li u thusa ho fana ka lihlahisoa tse tšoarellang nako e telele, tse sebetsang hantle haholo tseo bareki ba hao ba ka li tšepang.
