Kusukela ngonyaka we-1980s, ama-admixtures, ikakhulukazi ama-ejenti aphezulu akhuphukayo aphezulu, akhuthaze kancane kancane futhi asetshenziswe emakethe ekhonkolo yasekhaya, ikakhulukazi ukhonkolo onamandla okhonkolo. Njengoba uMalhoTRA ekhomba engqungqutheleni yezwe lokuqala mayelana nokumangaliswa kokhonkolo Kwakukhona kuphela iziqubu ezibalulekile zobuchwepheshe obukhonkolo eminyakeni edlule, enye yazo okwakuyintuthuko yomoya ongenayo ngawo-1940, okwashintsha ubuso bokhonkolo baseNyakatho Melika;Superplastimizerkungenye impumelelo enkulu ezoba nomthelela omkhulu ekukhiqizweni nasekusetshenzisweni kokhonkolo iminyaka eminingi okuzayo.

SuperplastimizerKwamanye amazwe abizwa kakhulusuperplastimizer, njengoba igama lisikisela, lilungele kakhulu ukulungiswa kwe-conkcrete ehlanganisiwe. Vele, ilungele kakhulu ukuxubeka okuxubile ngokugeleza okukhulu, ivolumu enkulu ethambile kanye nesilinganiso esiphansi samanzi, okungukuthi, ukupompa ukhonkolo onamandla aphezulu.

Kodwa-ke, kolunye ukhonkolo, njengokhonkolo othululelwa ekwakhiweni kwedamu le-hydraulic, ubukhulu obukhulu bezinhlayiyana bukhulu (kuze kube ngu-150mm), ivolumu elincanyana lincane futhi ukugeleza akukukhulu Ngokusebenzisa isenzo esinamandla sokudlidliza noma isenzo sokudlidliza, ukuncipha kwamanzi okusebenza kahle kungenzeka kungafanele. Ukuze ugcine isilinganiso se-manzi-single singashintshiwe, ukuze sihlangabezane nemishini yemishini yempahla edingwa yidizayini yokwakheka, yehlisa ukusetshenziswa kwamanzi, futhi ihlise ukwakhiwa kokonga njengombono, ukwakhiwa kwamadamu amaningi asekhaya ahlanganiswe nokusebenza kahle Amanzi anciphise. Eqinisweni, isicelo esinjalo siyinkinga, ngoba ukwenziwa kokhonkolo we-hydraulic kuxutshwe nohlobo lokufaka umoya noma uhlobo lwe-lignin lokunciphisa amanzi ajwayelekile, isilinganiso sabo sokuncipha kwamanzi sincane, futhi ngenxa yomphumela wokufaka umoya, ngakho-ke Lapho ukusetshenziswa kwamanzi kanye nenani lezinto zokubhala ngocingo zincishiswa ngasikhathi sinye, okungukuthi, lapho ivolumu ye-slurry incishiswa, ingalondoloza ibhalansi enzima. Ukuqinisekisa ukuthi kunendawo eyanele yokugcwalisa i-aggregate, bopha i-aggregate futhi unikeze kancane okusebenzayo kuyadingeka ukuthi le ngxube ihlanganiswe ngemuva kokuthulula.

Ngaphezu kwalokho, amandla acindezelayo enhlanganisela anciphisa i-ejenti yokunciphisa amanzi aphezulu ukunciphisa isilinganiso se-mage binder kungathuthukiswa kakhulu ngemuva kokuqina, kepha ukuqina kokukhula kwamandla kuvame ukukhula, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuwohloka kuzokwanda, ngakho-ke ukuzwela okuzokwenyuka, ngakho-ke, Ukwakhiwa kwepaneli yekhonkolo noma iphaneli yebhuloho kufanele kuqaphele nge-ejenti yokunciphisa amanzi aphezulu. Eqinisweni, lapho kulungiswa inani elikhulu kakhulu le-C30 ekwakhiweni komphakathi kanye nobunjiniyela bomphakathi (kufanele balandise isikhathi esingaphezu kwe-1/2 akuyona into ebalulekile.
