Qhob: Cov khoom, ntxiv kev sib piv thiab kev tswj hwm zoo

Cov qhob dav yog siv dav siv cov khoom siv uas paub rau nws lub zog, durability, thiab versatility. Ntawm no yog cov khoom tseem ceeb ntawm cov pob zeb ua kom tau siv los txhim kho cov khoom no, pom zoo cov kev ntsuas ntxiv:

Cov khoom ntawm cov pob zeb ua:

1. Compressive lub zog: muaj peev xwm ntawm cov pob zeb ua kom tiv thaiv axial loads, ntsuas hauv phaus square nti (pawm) lossis mopapals (mpa).
2. Lub zog tensile: lub peev xwm ntawm cov pob zeb ua kom tiv thaiv cov rog tsis sib haum, uas feem ntau qis dua qis dua li compressive lub zog.
3. Qhov ruaj khov: Cov pob zeb ua kom tsis kam rau huab cua, tshuaj lom neeg tawm tsam, puas tsuaj, thiab lwm yam kev puas tsuaj rau lub sijhawm.
4. Kev ua haujlwm: qhov yooj yim nrog uas qhob ua kom sib xyaw, muab tso rau, sib xyaw, thiab ua tiav kom ua tiav qhov xav tau zoo thiab ua tiav.
5. Qhov ceev faj: Qhov loj ntawm ib teev ntawm cov pob zeb ua, uas cuam tshuam rau nws qhov hnyav thiab cov teeb meem.
6. Shrinkage thiab creep: kev hloov pauv hauv ntim thiab deformation dhau sijhawm vim qhuav, ntsuas hluav taws xob, thiab kev thauj khoom.
7. Permeability: Cov pob zeb ua kom muaj peev xwm tiv thaiv cov tso dej, roj av, thiab lwm yam tshuaj los ntawm nws cov hws thiab cov hlab ntsha.

Cov khoom ntxiv thiab lawv cov haujlwm:

1. Dej-txo cov neeg sawv cev (superplasticizers): txhim kho kev ua haujlwm thiab txo cov ncauj lus kom muaj zog yam tsis muaj zog.
2. Huab cua-Entraining cov neeg sawv cev: Qhia cov pa me ntawm cov npuas txhawm rau txhim kho khov-thaw kev tiv taus thiab ua haujlwm.
3. Retarders: ncua sijhawm sijhawm tso cai rau kev thauj mus los ntev dua, tso chaw, thiab lub sijhawm tag.
4. Accelerators: ceev ceev chaw teeb lub sijhawm, tshwj xeeb yog muaj txiaj ntsig hauv huab cua huab cua txias.
5. Pozzolans (piv txwv li, ya tshauv, silica fume): durability, thiab txo cov calmerility los ntawm reacium hydroxide los ua cov cementiousious.
6. Fibers (piv txwv li, cov hlau, hluavtaws): Txhim kho tawg, cuam tshuam kuj, thiab lub zog tensile.
7. Corrosion Inhibitors: Tiv thaiv qhov cuab lub zog tiv thaiv kev tiv thaiv corrosion los ntawm chloride ions lossis carbonation.

Pom zoo Additive Ecpive Rectios:

• Cov kev sib piv tshwj xeeb ntawm cov khoom ntxiv nyob ntawm cov yam uas xav tau xws li cov khoom lag luam uas muaj feem ntau, cov kev mob ib puag ncig, thiab cov phiaj xwm kev xav tau.
• Cov kev sib piv yog feem ntau qhia tias feem pua ​​ntawm cov xis mas tag nrho lossis tag nrho cov pob zeb sib xyaw.
• Kev txiav txim siab yuav tsum tau txiav txim siab raws li kev kuaj sim, kev sib xyaw, thiab cov qauv kev ua tau zoo.

Kev tswj kev ntsuas zoo:

1. Kev Kuaj: Ua cov ntawv xeem ntawm cov ntaub ntawv raw (piv txwv li, agent, cement, ntxiv) kom paub tseeb nrog cov qauv kev cai thiab cov kev qhia tshwj xeeb.
2. Batching thiab sib xyaw: siv qhov hnyav thiab cov khoom siv ntsuas rau cov txheej txheem batch, thiab ua raws cov txheej txheem tsim kom zoo los ua kom tiav cov kev sib txuam thiab xwm yeem.
3. Kev Ua Haujlwm thiab Kev Kuaj Xyuas Ib Ntus: Tso cov tw khib nyiab, txaus cov kev ntsuam xyuas, lossis cov kev xeem sib dhos los ntsuas kev ua haujlwm ua haujlwm raws li xav tau.
4. Kev kho mob: Siv cov qauv tsim nyog (piv txwv li, kev kho kom sov, kho cov yeeb yaj kiab, kho cov kua dej ziab) kom tiv thaiv kom qhuav thiab txhawb kom dej.
5. Lub Zog Ntsuas Kev Ntsuas: Soj ntsuam qhob zog kev txhim kho los ntawm cov qauv ntsuas kev ntsuas) ntawm ntau lub hnub nyoog los txheeb xyuas cov qauv tsim qauv.
6. Cov Kev Ruaj Ntseg Zoo / QA (QA / QC) Cov Kev Kawm QA / QC, thiab kev kho kom muaj xwm yeem thiab kev yoog raws li cov lus qhia tshwj xeeb.

Los ntawm kev nkag siab cov khoom ntawm cov pob zeb ua, tswj cov khoom sib piv tsim nyog, thiab kev siv cov khoom siv ntxiv uas tau ua tiav thiab txhim kho lub zog thiab kev ua haujlwm ntev thiab ntev.
