Kev tu vaj tse txhua hnub, qhov kub thiab av noo tsis tuaj yeem lav tau, uas feem ntau ua rau muaj teeb meem tawg. Tom qab tshem tawm cov npoo npog los yog formwork ntawm cov pob zeb, kev ntsuas xws li kev ywg dej los yog npog cov dej yuav tsum tau ua kom ntub cov pob zeb, los yog thaum lub pob zeb ntog nyob rau hauv ib qho chaw ntub dej, cov pob zeb uas tau nthuav tawm yuav tsum tau them sai sai los yog qhwv nrog geotextiles, thiab ces ntaub qhwv ntaub yas.
Thaum winding, lub windings yuav tsum tau zoo lawm, tag nrho sib tshooj ib leeg, thiab muaj condensation ntawm lub puab nto. Nyob rau hauv cov cheeb tsam uas tej yam kev mob tso cai, lub ntub curing lub sij hawm ntawm pob zeb pob zeb yuav tsum tau ncua kom ntau li ntau tau. Nyob rau hauv cov txheej txheem tom qab ntawm kev saib xyuas kab noj hniav, yog tias qhov kub ntawm cov dej curing poured rau ntawm cov pob zeb saum npoo yog qis dua li ntawm cov pob zeb, qhov kub ntawm qhov sib txawv ntawm ob yuav tsum tsis pub tshaj 15 ° C.
Steam curing yog ib txoj kev tshawb fawb ntawm kev kho.

Ntawm qhov chaw tsim kho, kuv hnov ib co neeg ua haujlwm tsim kho hais tias kev saib xyuas yog xyuas kom cov cement muaj dej txaus rau dej. Nyob rau hauv lub caij ntuj sov, pob zeb dries thiab teem sai sai. Pob zeb poob dej sai tshaj plaws thiab tawv sai sai thaum raug tshav ntuj. Nws yog ib qho yooj yim.
