Ukusukela kwiminyaka yoo-1980, ubukhulu becala, ubukhulu becala ukunciphisa amanzi okunciphisa amanzi, khuthazwe ngokuthe ngcembe kwaye kuqinisekisiwe kwimakethi yekhonkrithi yasekhaya, ngakumbi kwikhonkrithi enkulu kwaye ikhutshiwe ikhonkrithi, kwaye ibe zezinto ezinokubangela ukuba zibonakale. Njengoko i-malhotra yachazwa kwinkomfa yokuqala yamazwe aphesheya kwikhonkrithi yekhonkrithi: "Ukuphuhliswa nokusetyenziswa kwamandla okunciphisa amanzi ngendlela ebaluleke kakhulu kwinkqubela phambili yeteknoloji ye-20. Kwakukho kuphela iziqwengana ezibaluleke kakhulu ezibalulekileyo kwitekhnoloji yekhonkrithi kwiminyaka yeminyaka, enye yazo yayikukuphuhliswa komoya ongenayo ngo-1940, nto leyo eyatshintsha ubuso betekhnoloji yaseMntla Merika;I-superplastikizerOlunye uqhawulo-mtshato olukhulu oluya kuba nefuthe elikhulu kwimveliso kunye nokusetyenziswa kwekhonkrithi iminyaka emininzi ezayo.

I-superplastikizerKwamanye amazwe abizwa kakhului-superplastikizer, njengoko igama libonisa, lifanelekile kakhulu ukulungiselela umxube wekhonkrithi we-superplastic. Ewe kunjalo, kufanelekile ukuxuba umxube ngokuhamba okukhulu, ivolumu yesilayidi esikhulu kunye nomyinge we-binder ophantsi kunye nomyinge wamanzi aphantsi, oko kukuthi, mpomporing amandla aphezulu.

Nangona kunjalo, ngenye ikhonkrithi, enjengekhonkrithi egalelwe kwi-Hydraulic Dam, ubungakanani be-aggregate inkulu (ukuya kuthi ga kwi-150mm), ivolumu ye-snark incinci kwaye ikhonkrithi ifanele idityaniswe Ngokusebenzisa intshukumo eqinileyo okanye isenzo sokuqengqeleka okukhulu, ukunqongophala kwamanzi aphezulu kusenokungalunganga. Ukuze ugcine umlinganiso womlinganiso we-binder wamanzi ongaguqukiyo, ukuze ufezekise iiparamitha zepropathi ezifunwa nguyilo lolwakhiwo, ukunciphisa ukusetyenziswa kwamanzi, kunye nokunciphisa umbandela wesamente kunye noluvo oluphezulu Umgangatho wamanzi. Ngapha koko, isicelo esinjalo siyingxaki, kuba ikhonkrithi eyadlulayo ixutywe ne-arhente yokungena komoya okanye i-LINGIN uhlobo lomgangatho wamanzi, kwaye ngenxa yesandi sombala we-surrry, kunjalo Xa ukusetyenziswa kwamanzi kunye nenani lezinto zokwenzamente zincitshiswa ngaxeshanye, oko kukuthi, xa ivolumu yokutsala incitshisiwe, inokugcina ibhalansi enqabileyo. Ukuqinisekisa ukuba kukho indawo eyaneleyo yokugcwalisa i-Aggregate, isonge i-Aggregate kwaye ibonelele ngesilayidi esisebenzayo esifanelekileyo kumxube ukuba sidibane emva kokuthululwa.

Ukongeza, amandla engcinezelo yomxube wokunciphisa amanzi aphezulu okunciphisa umlinganiso we-Binder wamanzi onokuthi aphuculwe kakhulu emva kokukhula, kodwa imvakalelo yokukhula kwamandla ihlala incinci, kwaye ngokubanzi, Ukwakhiwa kwePrimete Pavement okanye ipaneli yebhulorho kufuneka ilumkele iarhente ephezulu yokuphuhlisa amanzi. Ngapha koko, kulungiselelo lweyona mali inkulu ye-C30 kulwakhiwo lwamabandla kunye nobunjineli boburhulumente (kufuneka banikezele ngaphezulu kwe-1/2 ye-TREGE) okanye amabakala aphezulu e-probrimere ye-Insormenti, okanye ayisiyonto ibalulekileyo.
