Qhov cuam tshuam ntawm cov duab ntawm cov cement hais txog kev ua haujlwm ntawm superplasticizer yog tias tom qab cov cement sib xyaw, qhov loj thiab nyuaj ntawm cov qauv flocculation ntawm cov duab sib txawv ntawm cov cement hais sib txawv, thiab cov dej ntawm cov cement slurry yog qhov sib txawv heev. Kev ntxiv cov dej ua kom zoo dua qub muaj cov chaw ua haujlwm sib txawv thiab tsim cov txiaj ntsig sib txawv, uas ua rau cuam tshuam rau nws lub peev xwm ua haujlwm.
Cov kev tshawb fawb tau qhia tias thaum cov cement ua cov duab yog cov pob zeb tawg, cov superplasticizer ntxiv muaj cov txiaj ntsig muaj zog ntau dua li thaum cov cement ua cov duab zoo li pebble. Nws tuaj yeem nkag siab tias thaum cov cement sib xyaw hauv lub xeev tau sib xyaw, nws yooj yim dua los tsim cov qauv flocculation, tsim cov qauv flocculation ruaj khov dua thiab cov qauv txuas ntxiv mus, uas yog qhov zoo rau superplasticizer kom ua nws tus kheej ua haujlwm tau zoo. Cov txheej txheem flocculation tsim los ntawm pebble-puab cov cement hais yog nquag ua kom tawg. Txawm hais tias tsis ntxiv superplasticizer, ib feem ntawm cov dej dawb yuav tawg thiab koom nrog kev sib xyaw ntawm cov cement slurry. Ua li no, cov nyhuv ntawm superplasticizer raug txo.' tsis tuaj yeem ua tiav.
