Cemement admixtures ua ib lub luag haujlwm tseem ceeb hauv kev ua yeeb yam, feem ntau yog suav nrog cov hauv qab no:
Txhawb nqa kev tsim qauv thiab kev ruaj ntseg ntawm txheej txheem cement, ua rau nws kub siab thiab kub thiab kev nyab xeeb ntawm txheej xis mas.
Txhim kho lub zog thiab lub zog ntawm cov txheej txheem xissing: los ntawm kev hloov kho cov neeg sawv cev, thiab lwm yam. ruaj khov.
Txhim kho kev ua tiav ntawm Maas slurry: cementing ign2tures thiab lwm yam kev ua tau zoo ntawm cov nyhuv thiab kev ua haujlwm zoo ntawm kev ua haujlwm.
Ntau hom cementing admixtures thiab lawv cov haujlwm

Retarder: ntev lub sij hawm lub sij hawm ntawm xis mas thiab haum rau qee lub sijhawm uas xav tau lub sijhawm ua haujlwm ntev dua.
Defoaming tus neeg sawv cev: Txo cov npuas hauv Maas Slurry, tiv thaiv cov roj channel, thiab txhim kho cov cementing zoo.
Luag Reducer (Dispersant): Txo cov viscosity ntawm Maas Slurry, txhim kho nws cov xim, thiab pab txhawb kev tsim kho.
Dej poob tus neeg sawv cev: txo cov dej poob ntawm txoj kev nplua nuj thaum nqus cov txheej txheem thiab ua rau cov txheej txheem cementing kom xoob.
Anti-Roj Channeling Tus Neeg Sawv Cev: Tiv thaiv cov roj ntawm cov txheej txheem kev cai thaum lub sij hawm ua kom cov txheej txheem cementing.
Kev txo qis admixtures sab nraud (txo qis kev sib npaug ntawm cov cement slurry, haum rau qee zaus yuav tsum muaj qhov hnyav.
Anti-to sab nraud admixture (anti-to
Kev txhawb nqa: Txhim kho lub zog thaum ntxov thiab lig ntawm Maas Slurry kom ntseeg tau tias qhov kev ruaj ntseg ntawm txheej xis.
Peb yog tus neeg saib xyuas sab nraud admixture sab nraud): nce cov kev sib nqus tshwj xeeb ntawm cov cement slurry, haum rau lub sijhawm uas yuav tsum muaj qhov hnyav
