Kugwiritsa ntchito ma stabilizers a manja ndi njira yofunikira kwambiri pakuwongolera simenti. Cholinga cha simenti ndi pawiri: choyamba, kugwiritsa ntchito thumba kuti atseke zigawo za m'chitsime zomwe zimakonda kugwa, kutayikira, kapena zovuta zina, kupereka chitsimikizo cha kubowola kotetezeka komanso kosalala. Chachiwiri ndikulekanitsa bwino malo osungiramo mafuta ndi gasi, kuletsa mafuta ndi gasi kuyenda pamwamba kapena kutuluka pakati pa mapangidwe, kupereka njira zopangira mafuta ndi gasi.
Malinga ndi cholinga cha simenti, milingo yowunikira simenti yabwino imatha kutengedwa. Zomwe zimatchedwa kuti simenti yabwino zimatanthawuza kuti choyikapo chimakhala pakati pa chitsimecho, ndipo sheath ya simenti yozungulira bwaloyo imalekanitsa bwino khoma ndi khoma lachitsime ndi mapangidwe ake. Komabe, chitsime chobowoledwacho sichiri choyimirira ndipo chikhoza kupangitsa kuti pakhale milingo yosiyanasiyana ya chitsime. Chifukwa cha kupendekeka kwa chitsime, chosungiracho sichikhala mkati mwa chitsimecho, zomwe zimapangitsa kuti pakhale kutalika kosiyanasiyana ndi kukhudzana ndi khoma la chitsime. Kusiyana pakati pa casing ndi chitsime kumasiyanasiyana kukula, ndipo pamene slurry ya simenti imadutsa m'madera okhala ndi mipata yayikulu, slurry yoyambirira imasinthidwa mosavuta; M'malo mwake, kwa iwo omwe ali ndi mipata yaying'ono, chifukwa cha kukana kwamphamvu kwambiri, zimakhala zovuta kuti matope a simenti alowe m'malo mwa matope oyambirira, zomwe zimapangitsa kuti pakhale chodziwika bwino cha simenti slurry channeling. Pambuyo popanga njira, malo osungiramo mafuta ndi gasi sangathe kusindikizidwa bwino, ndipo mafuta ndi gasi zidzadutsa m'madera opanda mphete za simenti.
Kugwiritsa ntchito stabilizer ndiko kuyika choyikapo pakati momwe mungathere pakumanga simenti. Pakumanga zitsime zolowera kapena zokhota kwambiri, ndikofunikira kugwiritsa ntchito zolimbitsa manja. Kugwiritsiridwa ntchito kwa casing centralizers sikungangolepheretseratu slurry ya simenti kulowa mu poyambira, komanso kuchepetsa chiopsezo cha kusiyana kwa kuthamanga kwa casing ndikumamatira. Chifukwa chokhazikika chimayika choyikapo, chosungiracho sichimangiriridwa mwamphamvu pakhoma lachitsime. Ngakhale m'zitsime zokhala ndi mpweya wabwino, chosungiracho sichingatsekeke ndi makeke amatope opangidwa ndi kusiyanasiyana kwamphamvu ndikuyambitsa kubowola. Kukhazikika kwa manja kumatha kuchepetsanso kupindika kwa choyikapo mkati mwa chitsime (makamaka pachitsime chachikulu), zomwe zingachepetse kuvala kwa chida chobowola kapena zida zina zapabowo pobowola pobowola pambuyo poyikidwa, ndi kutenga nawo mbali poteteza bwalo. Chifukwa cha chithandizo cha stabilizer ya manja pa casing, malo olumikizana pakati pa casing ndi chitsime amachepetsedwa, zomwe zimachepetsa kukangana pakati pa casing ndi chitsime. Izi ndizopindulitsa kuti chotengeracho chitsitsidwe m'chitsime komanso kuti chotengeracho chisunthidwe pomanga simenti.
