Izici ze-ejenti enciphisa amanzi zithinta ngqo ukusebenza kwe-shrinkage kakhonkolo. Ngaphansi kokhonkolo ofanayo, isilinganiso se-shrinkage sikakhonkolo esine-ejenti yokunciphisa amanzi siphakeme ngo-35% ngaphezulu kwalokhu kukakhonkolo oncishisiwe amanzi. Ngakho-ke, imifantu ekhonkolo kungenzeka yenzeke. Nakhu ukuthi:
1. Umphumela wokunciphisa amanzi uncike kakhulu ezintweni zokwenziwa kokhonkolo kanye nokuxubana kwezilinganiso.
Izinga lokunciphisa lamanzi likakhonkolo liyincazelo eqinile kakhulu, kepha kuvame ukubangela ukungaqondi. Ezikhathini eziningi ezahlukene, abantu bahlala besebenzisa isilinganiso sokuncipha kwamanzi ukuveza umphumela wokunciphisa amanzi womkhiqizo.
Emthanjeni ophansi, uthatha i-ejenti ye-polycarboxxylate yokunciphisa amanzi njengesibonelo, kuye kwafakazelwa ukuthi izinga lawo lokunciphisa amanzi likhulu kakhulu kunalelohlobo lamanye izinhlobo zama-ejenti ancishisiwe amanzi, futhi linomphumela ongcono wokunciphisa amanzi. Kodwa-ke, kufanele kuqashelwe ukuthi kuqhathaniswa namanye ama-ejenti ancishisiwe amanzi, umphumela oncishisiwe wamanzi wama-polycarboxylate agents ancishiswe amanzi athinteka kakhulu yizimo zokuhlola.
Phakathi kwezinto ezithonya umphumela wepulasitiki wePolycarboxylate Superplasticizer, isilinganiso sesihlabathi kanye nezinto eziyizinhlayiyana zokuhlanganiswa kokhonkolo kubuye kube nomthelela omkhulu. Uma kuqhathaniswa namanye ama-ejenti aphezulu akhulisa amanzi afana nochungechunge lwe-naphthalene, umphumela wepulasitiki wama-polycarboxylate agents ancishiswe amanzi athinteka kakhulu ngokuqukethwe kodaka okuhlanganisiwe okuhle.
2. Umphumela wokunciphisa amanzi uncike kakhulu emthanjeni we-ejenti enciphisa amanzi.
Ngokuvamile, njengoba umthamo we-ejenti enciphisa amanzi uyanda, izinga lokunciphisa amanzi ngokhonkolo libuye likhuphuke, ikakhulukazi ama-polycarboxylic acid acid anchents acijile abi, umthamo uthinta ngqo umphumela wokunciphisa amanzi.
Kodwa-ke, kukhona okuhlukile kwizicelo ezisebenzayo. Okusho ukuthi, ngemuva kokuthi umthamo othile ufinyelelwe, umphumela wokunciphisa amanzi "uyancipha" njengoba umthamo uyanda. Lokhu kungenxa yokuthi ngalesi sikhathi ingxube kakhonkolo iba lukhuni, ukhonkolo uhlushwa ukopha okukhulu, futhi umthetho oshisayo awusakwazi ukuveza ukuncipha kwaso.
3. Ukusebenza kwengxube kakhonkolo elungiselelwe kuzwela kakhulu ukusetshenziswa kwamanzi.
Izinkomba zokusebenza kokuhlanganiswa kokhonkolo zivame ukuboniswa ezicini ezinjengokugcinwa kwamanzi, ukubumbana, kanye nokwakheka. Ukhonkolo olungiselelwe usebenzisa ama-superplastizer asuselwa ku-polycarboxylic acid awahlali njalo ahlangabezane nezidingo zokusebenzisa. Ukusebenza kwengxube ekhonkolo elungiselelwe kuzwela kakhulu ukusetshenziswa kwamanzi, futhi ezinye izinkinga zivame ukwenzeka.
