Khoom Description
Cov nyhuv ntawm qhob admixture retarder yog qhov tsim nyog rau kev thauj mus los ntev ntawm cov pob zeb thaum lub sij hawm thauj mus los thiab cov pob zeb hauv qhov kub thiab txias. Nws yog tshwj xeeb tshaj yog siv raws li ib tug grouting admixture thiab dej txo tus neeg sawv cev los txhim kho lub zog thiab durability ntawm pob zeb.
hom kev ua
Lub pob zeb admixture retarder ntseeg hais tias cov retarder adsorbs ntawm C3A theem hauv cov cement thiab tsim ib zaj duab xis nyob ib ncig ntawm cov cement hais, nthuav tawm lossis txo cov tshuaj tiv thaiv nrog dej. Tom qab ib lub sij hawm, zaj duab xis yog decomposed thiab ib txwm hydration txuas ntxiv. Qhov no yog qhov sib xyaw yooj yim, thiab muaj laj thawj ntseeg tias qhov ncua sij hawm kuj cuam tshuam nrog C3S, vim tias qhov ncua sij hawm tuaj yeem txuas ntxiv mus rau ntau hnub.
qhov zoo
a) Lub hom phiaj ntawm cov pob zeb ua los ntawm hydroxycarboxylic acid admixture yog feem ntau qis dua li ntawm kev tswj cov khoom sib xyaw.
b) Cov ntaub ntawv zoo li no (lignosulfonates uas muaj suab thaj thiab hydroxycarboxylic acid derivatives) muaj kev cuam tshuam ntau dua hauv qee kis thiab yog li ntawd muaj peev xwm txo cov dej ntau dua.
c) Ua kom durability.
cuam tshuam
a) Thaum lignosulphonate raws li cov khoom siv, ces cov ntsiab lus huab cua yuav yog {{0}}.2 mus rau 0.3% siab dua tshwj tsis yog cov khoom ntawm tributyle phosphate hom ntxiv.
b) Raws li cov ntsiab lus ntawm cov dej nce, yog li muaj kev nyiam rau ziab shrinkage.
daim ntawv thov
a) Yog tias cov pob zeb npaj tau yuav tsum tau thauj mus ntev, ces hom admixture no tuaj yeem zam qhov teeb meem ntxov ntxov.
b) Thaum tso lossis thauj khoom ua vaj tse nyob rau hauv ib puag ncig kub.
c) Cov pob zeb loj loj
d) Sliding formwork qhob kev tsim kho
