Lapho uCement Hydrate, kwakha isakhiwo se-floccution esisonga amanzi ngaphakathi. Ukuze wenze i-hydration iphelele futhi ithuthukise ukusebenza kokhonkolo, amanzi amaningi adinga ukungezwa. Ukungezwa kwama-admixtures kungaba yizikhangiso eziqondiswa phezulu ebusweni bezinezinhlayiya zokwenza usimende, ukuze ingaphezulu lezinhlayiya zensimbi linecala elifanayo, elihlukaniswe ngamanzi asongelwe ekwakhekeni kwesimende selakhiwo, okuvumela amanzi amaningi ukuthi abambe iqhaza ku ukusabela kwe-hydration futhi kuthuthukise uketshezi.

Kodwa-ke, ngenxa yezizathu ezahlukahlukene, ama-admixtures kanye nosimende kuthambekele ezinkingeni zokungalingani. Ukubonakaliswa okuyinhloko yile:

(1) Ukuhlanganiswa kwe-Admix akukuthuthuki kakhulu ukusebenza kokusebenza kukakhonkolo;

(2) Ukulahleka kukakhonkolo kukhulu kakhulu noma kusethi ukhonkolo ngokushesha okukhulu;

.

Lezi zinkinga zizothinta kakhulu ikhwalithi kakhonkolo kasimende, zilethe izingozi ezifihliwe kwikhwalithi yephrojekthi, futhi kubangele nezingozi zobunjiniyela ezimweni ezinzima, okuholela ekulahlekelweni okubalulekile kwezomnotho.

Ukuxazulula inkinga yokungalingani phakathi kwama-admixtures kanye nosimende, ukuvikela kungukhiye, futhi ukunakwa kufanele kukhokhwe ekukhetheni kwezinto zokwakha kanye nokuhlolwa kwezinto ezingenayo. Ukuhambisana kwe-admixtures kanye nosimende kuyinkinga eyinkimbinkimbi ngokwengeziwe. Uma kunenkinga yokungalingani phakathi kwama-admixtures kanye nosimende, abakhiqizi bakhonkolo kufanele bathathe izisulu ngesikhathi. Ngokwesimo, ngokususelwa ezivivinyweni, hlaziya futhi uthole izizathu, lungisa isilinganiso sekhonkolo

Imvamisa, inani le-Fly Ash lingashintshwa, inani lokuhlanganiswa lingandiswa, izinsalela zesigaba samanzi zokuhlanganiswa ngokhonkolo zingandiswa, isilinganiso samanzi-usimende singagcinwa singashintshiwe, futhi inani likasimende lingakhuphulwa, Kepha ngokungangabazeki lokhu kuzokhulisa izindleko zeyunithi. Indlela yokwengeza yesibili nayo ingasetwa ngesikhathi sokukhiqiza, okungukuthi, ukuncibilika kwefektri kulawulwa ngo-80-100, futhi isixazululo sokuhlanganiswa sivuselelwa cishe imizuzu emi-2 ngaphambi kokusebenzisa esizeni sokwakha ukuze sikuguqule ku-140. Lokhu kwelashwa kuningi kwezomnotho futhi kuyaphumelela.

Abakhiqizi bakhonkolo bavame ukudinga ama-admixtures ukuzivumelanisa nokwehla ngenxa yokusungula okukhulu, okungukuthi, ukhiqizi we-admixture kudingeka alungise ifomula, lungisa uhlobo kanye nomthamo wokuhlanganiswa kwamanzi ngokusho kukakhonkolo osetshenziswa umkhiqizi ukhonkolo, noma Faka i-Plistic ne-Agenct Ejenti Yokufaka umoya ngokuqina kwe-bubble, njll. Lapho kunqunywa isilinganiso sokhonkolo senkomba ngesikhathi sokwakha, isikhathi sokusetha ukhonkolo idinga ukubhekwa, futhi ukuhlanganiswa kufanele kube nengxenye yokubuyisa. Uma amazinga okushisa aphezulu ahla, ukuhlanganiswa okuningi kusetshenziswa kukhonkolo, bese ifomula alilungiswa ngesikhathi, ukhonkolo ngeke kuthathwe isikhathi eside, okuzothinta kakhulu amandla kakhonkolo. Ehlobo, ukwakhiwa kufanele kugweme izinga lokushisa eliphakeme nomoya onamandla ntambama, futhi izinto ezingavuthiwe kufanele zipholile. Isilinganiso sesihlabathi ngesikhathi sokwakha kufanele siguqulwe ngokufanele ngokosayizi wobukhulu besihlabathi kanye nokuqina kwe-aggregate.
