Izidingo ezinkulu neziphakeme zokusebenza kukakhonkolo. Kusukela ekuthuthukisweni kwezingxube zikakhonkolo ngeminyaka yawo-1940, ukuthuthukiswa kwayo akukashintshi nje kuphela isakhiwo sangaphakathi sikakhonkolo oqinile kusukela kumazinga angabonakali kanye nangama-submicroscopic, kodwa futhi kwashintsha isakhiwo sikakhonkolo omusha enqubweni. .I-concrete admixture, eyaziwa nangokuthi i-dispersant noma i-plasticizer, iyinhlanganisela evame ukusetshenziswa futhi ebalulekile.

Ukuze ulungiselele ukhonkolo omusha ngezakhiwo ezinhle zokugeleza, isakhiwo se-viscous esinciphisa ukugeleza phakathi kwezinhlayiya ze-samente kufanele sihlakazwe, ukuze izinhlayiya ze-samente zihlakazeke ngokugcwele emanzini.Kunezakhiwo eziningi ezithinta ukuhlanganiswa kukasimende, njengokubunjwa kwamaminerali kasimende, ukuma nobukhulu bezinhlayiya zikasimende, ubuqotho be-crystallization yamaminerali, nezimo zokusebenza kanye nezici zemvelo.Lezi zici ezingenhla zilawula ngokuqondile noma ngokungaqondile ukuzinza kwezinhlayiya zikasimende ku-slurry.Izimo ezihlukene eziphakathi zingashintsha inani le-charge kagesi yezinhlayiya ze-cement ku-slurry, okungukuthi, ukushintsha ukuxoshwa kwe-electrostatic phakathi kwezinhlayiya.

Lapho inani elifanele lengxube kakhonkolo lengezwa kukhonkolo entsha, amaphuzu ezinhlayiya zikasimende ayanda, futhi ukucindezelwa kukagesi phakathi kwezinhlayiya zikasimende kwanda kakhulu, okuholela ekwehleni kwe-viscosity kakhonkolo omusha, okukhuthaza ukuzinza kwezinhlayiya zikasimende. lonke uhlelo lokuhlakazeka.anda, futhi ne-liquidity yaba ngcono.

Ngokuvamile, ukwengeza inani elifanele lengxube kakhonkolo kusimende kunamathisele kungakhuthaza ukhonkolo omusha ukukhombisa i-thixotropy eqinile.Lokhu kungenxa yokwakhiwa kwesendlalelo sefilimu esincibilikisiwe ebusweni bezinhlayiya zikasimende ezikhangiswe ku-ejenti yokunciphisa amanzi kanye nokwanda kwamandla.Uma kukhona ukudlidliza okuncane, kuzobonisa uketshezi olungcono.I-thixotropy yokhonkolo omusha ngaphandle kwe-superplasticizer ibuthakathaka kakhulu.
