Concrete Expansive Agent

Concrete expansive agents yog siv los npaj expansive qhob, nrog rau shrinkage-compensating pob zeb thiab nws tus kheej-stressing pob zeb. Shrinkage-compensating pob zeb tuaj yeem them rau qhov ziab kom qhuav, ua kom cov pob zeb ua kom zoo dua qub, thiab txhim kho nws cov impermeability. Hauv kev tsim vaj tsev engineering, nws feem ntau yog siv rau kev tiv thaiv dej thiab tawg. Nws yog feem ntau siv rau hauv kev npaj ntawm qib high-qib waterproof qhob thiab kom tsim nyog ncua qhov kev ncua deb ntawm expansion pob qij txha los yog post-cast strips.

Concrete expansive agents belongs rau hom calcium sulfoaluminate thiab tsis muaj sodium ntsev, yog li tsis txhob muaj alkali-aggregate tshwm sim hauv cov pob zeb. Lawv muab kev ua haujlwm zoo, kev ua haujlwm ruaj khov, thiab ua kom muaj zog ntxiv. Ordinary pob zeb zoo li tawg vim shrinkage, uas tuaj yeem ua rau to thiab txo cov kav ntev. Los ntawm kev sib xyaw 8% -12% expansive tus neeg sawv cev rau hauv cov cement, shrinkage-compensating pob zeb tuaj yeem npaj tau, ua kom muaj kev tiv thaiv tawg thiab muaj peev xwm tiv thaiv dej ntawm cov pob zeb. Qhov no tuaj yeem tshem tawm qhov xav tau rau kev tiv thaiv sab nraud, txuas ntxiv qhov sib nrug ntawm cov pob qij txha tom qab, thiab tiv thaiv qhov kub thiab txias ntawm cov pob zeb loj thiab cov pob zeb muaj zog.

Cov lus qhia siv

Qhov pom zoo npaum li cas ntawm tus neeg sawv cev nthuav dav yog 8-12%. Rau kev npaj cov pob qij txha tom qab cam khwb cia thiab reinforcing strips, cov koob tshuaj yuav tsum tau nce kom tsim nyog.

Cov pob zeb npaj nrog cov neeg ua haujlwm nthuav dav tuaj yeem siv cov txheej txheem ntawm tus kheej-waterproofing, kev sib koom ua ke ntawm lub tsev thiab kev ua haujlwm tsis zoo, yog li tshem tawm cov dej tsis zoo sab nraud thiab ua kom yooj yim rau cov qauv.

Expansive agent pob zeb tuaj yeem siv ultra-ntev steel-reinforced qhob seamless tsim thiab kev tsim kho cov txheej txheem, txo cov txheej txheem kev tsim kho, ua kom yooj yim, thiab txo lub sijhawm tsim kho. Nws tso cai rau thaj tsam loj-nruab nruam pouring yam tsis tau tawm hauv cov pob qij txha tom qab cam khwb cia, thiab nws kuj tuaj yeem siv los kho cov pob zeb ua pob zeb tom qab cam khwb cia.

Cov kev ceev faj

Nyob rau ntawm qhov chaw sib tov lossis batching cog, cov ntaub ntawv yuav tsum tau muab faib ua raws li qhov kev txiav txim siab shrinkage-compensating qhob mix ratio, thiab cov cuab yeej ntsuas yuav tsum yog. Nyob rau hauv-dosing tus neeg sawv cev expansive yuav tsis ua tau raws li lub shrinkage them nyiaj yuav tsum tau, thaum overdosing yuav ua puas lub pob zeb qauv.

Lub sijhawm sib xyaw rau pob zeb nrog tus neeg sawv cev nthuav dav yuav tsum tau txuas ntxiv 30 vib nas this piv rau cov pob zeb zoo tib yam. Qhov ntsuas kub ntawm qhov tso tawm yuav tsum qis dua 30 degree, qhov siab dawb lub caij nplooj zeeg thaum lub sij hawm nchuav yuav tsum tswj tsis pub dhau 2 meters, thiab kev co yuav tsum sib npaug thiab meej, tsis txhob muaj kev vibration lossis dhau kev vibration.

Lub pob zeb uas muaj tus neeg sawv cev nthuav dav yuav tsum tau rov troweled ua ntej qhov kawg teeb tsa los tiv thaiv qhov tawg ntawm qhov tawg.

Tom qab-pouring curing ntawm expansive agent pob zeb yog qhov tseem ceeb. Nyob ntawm qhov kub thiab txias, kev kho dej yuav tsum tau ua kom raws sijhawm kom cov dej ntws tawm tsis tu ncua rau tsawg kawg 7 hnub. Nyob rau hauv huab cua txias, xyuas kom cov pob zeb kub siab tshaj 5 degree thaum lub sij hawm pouring, thiab tam sim ntawd npog nrog yas zaj duab xis thiab rwb thaiv tsev ntaub ntawv rau kho.

Tom qab nchuav expansive agent pob zeb, hauv qab daus backfilling yuav tsum tau ua kom sai li sai tau, thiab vov tsev waterproofing thiab rwb thaiv tsev txheej yuav tsum tau thov sai li sai tau.
