Technical Thiab Economic Los Ntawm Cov Khoom Uas Muaj Kev Ua Tau Zoo Ntawm Cov Khoom Siv Dej Txias Dej

① Thaum cov dej siv tsis hloov pauv, qhov poob ntawm cov pob zeb tuaj yeem nce los ntawm 10 mus rau 20cm;
② Ua kom lub zog ua haujlwm ntawm cov pob zeb tsis hloov pauv, cov dej tuaj yeem txo tau los ntawm 10% mus rau 50%, thiab cov pob zeb ua kom muaj zog tuaj yeem nce los ntawm 15% mus rau 20%, tshwj xeeb tshaj yog thaum ntxov zog nce yog qhov tseem ceeb dua;
③Thaum lub zog ntawm cov pob zeb tseem tsis hloov pauv, kev siv cov cement tuaj yeem txuag tau los ntawm 10% mus rau 15%;
④ Lub tshav kub tso tawm ntawm cov cement hydration qeeb thiab lub tshav kub tso tawm lub ncov qeeb;
⑤ Qhov tshwm sim ntawm pob zeb los ntshav thiab kev sib cais tau zoo heev;
⑥ Cov dej permeability ntawm cov pob zeb yuav raug txo los ntawm 40% mus rau 80%, txhim kho lub peev xwm tiv thaiv permeability, Frost tsis kam, tshuaj corrosion thiab xeb;
⑦ Cov pob zeb tshwj xeeb tuaj yeem npaj tau, uas yog kev lag luam ntau dua, yooj yim thiab hloov tau dua li siv cov cement tshwj xeeb.
