Polycarboxylate superplasticizer muaj cov xwm txheej tseem ceeb ntawm cov khoom ntawm cov khoom ntawm cov cement slurry feem ntau los ntawm adsorption.
Cov nyhuv no feem ntau suav nrog cov hauv qab no:
(1) lub sijhawm ncua sijhawm pib lub sijhawm ntawm cov cement cement induction;
(2) txo qhov nro ntawm cov kua hauv qhov kev txiav cov cement slurry thiab cov viscosity ntawm lub kaw lus;
(3) Tawm tswv yim huab cua mus rau hauv cov kab ke los tsim cov npuas npuas, uas yog qhov tsim nyog rau qhov khiav ntawm cov pob zeb ua tshiab;
(4) txo cov shear yield kev ntxhov siab thiab yas viscosity ntawm cov cement slurry;
(5) Txo cov dej ua kom lub cev tsis haum thiab tso tawm cov cua sov ntawm cov pob zeb hauv av, txhim kho qhov ntim ruaj khov ntawm cov pob zeb
(6) vim muaj qhov cuam tshuam loj ntawm kev txo dej txhawm rau txhim kho kev cog lus ntawm pob zeb, thiab tom qab ntawd txhim kho lub zog ntawm qhob.
Tsis tas li ntawd, cov dej nyob ntawm tus neeg sawv cev txo qis yuav ua rau cov crystalline particle me me ntawm cov khoom siv dej kom me, uas yog qhov zoo rau kev txhim kho ntxiv ntawm cov pob zeb ua kom muaj zog.
