Ukususela kumbono womsebenzi we-concrete admixtures, sinokuyeka ukuhlelwa kwaye ngokukodwa sithintele iimeko ezine. Ngokusebenzisa i-admixtures efanelekileyo, sinokugqiba ulawulo lwesantya se-rheological yekhonkrithi. Ngokombono wokusetyenziswa kweentlobo ezahlukeneyo ze-concrete admixtures, iziphumo nazo zihluke. Emva koko, abavelisi be-concrete admixtures babelana ngokuthotyelwa kwe-concrete admixtures.
Phakathi kwabo, owona msebenzi uphambili we-ejenti yemvula kukunciphisa ukusetyenziswa kwamanzi ukugcinwa, ukunika ikhonkrithi ngoxinano olungcono kunye neempawu ezilastiki, kunye nokuphucula ukuqina kwayo kwesicelo.
I-arhente yokungenisa umoya kukuyeka ukuqiniswa kwe-solubility yekhonkrithi ephantsi, kwaye ugqibezele ulawulo lwee-cracks zangaphakathi kunye nokulungiswa okuqhubekayo kokungena ngokuguqulwa okusebenzayo kwesakhiwo sangaphakathi sekhonkrithi.
Ukongeza, izicelo ezininzi zekhonkrithi zineemfuno eziphezulu zokunganyanzeki. Abantu kufuneka bahlangabezane neemfuno zokwakha ngokusetyenziswa kwe-agent ye-precipitation ye-high-performance-performance-performance to improve the density of concrete.Ngaphezu koko, ukuqiniswa kwekhonkrithi kukulungele ukubola, kwaye abasebenzi abachaphazelekayo banokulawula izinga le-carbonation yekhonkrithi ngoncedo lwe-corrosion. ukusetyenziswa kwe-agent ye-precipitation.Ukuba ixabiso le-pH kwikhonkrithi libonisa ukuhla, ingxaki yentsimbi yentsimbi ehambelanayo nayo iya kuthintelwa kuluhlu olukhulu.
Ngenxa yeentlobo ezahlukeneyo, ukhetho lwe-concrete admixtures luya kubonisa ukungafani okucacileyo. Ukuze ubonise umphumo womsebenzi osebenzayo, abasebenzi abachaphazelekayo kufuneka bayeke ukulawula okufanelekileyo komlinganiselo we-admixtures ngokusebenzisa iimpawu zekhonkrithi ezahlukeneyo, kunye nokugcina ukuphuculwa okusebenzayo kokusebenza kwekhonkrithi ngokwayo. Phakathi, i-arhente yokunciphisa amanzi yi-concrete ye-concrete edibeneyo enokunciphisa ukusetyenziswa kwamanzi okuxutywa phantsi kwemeko yokuba i-slump yekhonkrithi ayitshintshanga. Emva kokufaka umxube wekhonkrithi, unokusasaza amaqhekeza e-samente, uphucule ukusebenza kwayo, unciphise ukusetyenziswa kwamanzi eyunithi, kunye nokuphucula umbane womxube wekhonkrithi; Okanye ukunciphisa ukusetyenziswa kwesamente yeyunithi ukugcina isamente.
