Cov khoom no yog qhov kev tsim hluav taws xob tshiab ib puag ncig ntawm cov hluav taws xob zoo ua rau cov dej ua kua dej txau rau cov tshuaj khib hluav taws xob raws li cov thev naus laus zis tshiab. Lub ntsiab ntawm cov hmoov yog polycarboxylate superplasticizeris, uas yog tsim los ntawm kev siv tshuab ua kom qhuav tshwj xeeb. Polycarboxylate raws cov dej ua kom dej hmoov, ua los ntawm cov tshuaj tsuag kom qhuav txheej txheem, nrog kev ua tau zoo thiab kev tiv thaiv ib puag ncig. Nws yog tshwj xeeb tshaj yog tsim rau cov ua haujlwm siab hmoov siv cov khoom siv, siv ua cov khoom xa khoom. Kev tawg zoo, dej siab txo tus nqi, hloov mus rau ntau cov xis mas. Kev npliag ntawm kev sib xyaw yog qhov zoo tshaj plaws thaum siv rau hauv pob zeb ua thiab pob zeb.

.Muaj cov qauv kev ua haujlwm
Nws yog dav siv nyob rau hauv qhuav cug thiab pob zeb ua tshuab, xws li nws tus kheej qib cug, cov khoom grouting, grouting tus neeg sawv cev thiab pob zeb ntawm cov qib sib txawv lub zog.
1.Txhais zoo li qub txo cov dej
2.Better slump cia cov nyhuv
3.Txhais ntau yam kom haum rau cov qauv tsim sib txawv
4. Txhawb nqa qhov ua tau zoo tshaj plaws ntawm kev tshuaj khib
5. Txhim kho cov khoom siv ruaj khov ntawm cov ntaub ntawv xis mas.
Ⅲ. Kev siv thiab kev ceev faj
1.Qhov khoom no tsis tuaj yeem noj tau. Yog tias nws raug txaws rau hauv qhov muag, ntxuav nws nrog dej hauv lub sijhawm
2. Nws yog cov kua qaub uas tsis muaj zog, tsis muaj tshuaj lom, tsis muaj corrosive thiab muaj kuab paug tom qab yaj hauv dej
Ⅳ. Pob thiab chaw cia khoom
1.Cov khoom no muaj cov ntaub ntawv muaj kev nyab xeeb cov ntaub ntawv thiab daim ntawv tso cai thauj mus los kev nyab xeeb cov ntaub ntawv
2.Qhov khoom no tau ntim hauv 20 kg kraft ntawv thiab yas ntim cov hnab ntim hnab zaj duab xis
3.Xam rau hauv qhov chaw qhuav, them sai sai rau cov dej noo-pov thawj, nrog lub txee ua haujlwm ntawm 12 lub hlis
