Iindidi eziqhelekileyo zokudibanisa kunye nendima yazo kwikhonkrithi esele ilungile:

I-concrete admixtures iyingxenye ebalulekileyo yokuphucula ukusebenza kwekhonkrithi, kunye neentlobo ezahlukeneyo ze-admixtures zineendima ezahlukeneyo kwikhonkrithi ekulungeleyo. Iindidi eziqhelekileyo ze-admixtures zinciphisa amanzi, i-accelerators, i-antifreeze agents kunye ne-preservatives. Njengenxalenye ephambili kwikhonkrithi, abanciphisi bamanzi banokunciphisa kakhulu umthamo wamanzi asetyenziswe kwikhonkrithi kunye nokuphucula ukusebenza kunye namandla ekhonkrithi. Ukusetyenziswa kwezinciphisi zamanzi kunokwenza ikhonkrithi ibe lula ukuyakha, i-fluidity engcono, kunye nokukhuthaza ukusasazwa okungcono kwamasuntswana e-samente, ngaloo ndlela kuphuculwe amandla okuqala kunye nokuchasana kwekhonkrithi.

I-accelerators inokukhuthaza ukuqina ngokukhawuleza kwekhonkrithi kunye nokunciphisa ixesha lokuqala lokumisela, elifanelekileyo kwiindawo eziphantsi zokushisa okanye iimeko apho kufuneka ukwakhiwa ngokukhawuleza. Ukwandiswa kwexesha leplastiki kunempembelelo ebalulekileyo ekuphuculeni ukusebenza kwekhonkrithi.

I-Antifros inomsebenzi wokukhusela ikhonkrithi phantsi kweemeko zokushisa eziphantsi, ezinokuthi zenze ikhonkrithi yakhiwe ngokuqhelekileyo phantsi kweendawo eziphantsi zokushisa, kunye nokukhusela ikhonkrithi ekuqinisweni ngokukhawuleza ngenxa yokushisa okuphantsi, okuchaphazela ukuphuhliswa kwamandla.

Izilondolozo zisetyenziselwa ukuxhathisa i-corrosion kwiindawo ezahlukeneyo kunye nokuphucula ukuqina kwekhonkrithi.

Ezi zidibaniso zekhonkrithi eziqhelekileyo zineempawu zazo kunye nokusetyenziswa. Ukukhetha okuchanekileyo kunye nokusetyenziswa kunokuphucula kakhulu ukusebenza kwekhonkrithi edibeneyo edibeneyo kunye nokuphucula ukusebenza kakuhle kunye nomgangatho weprojekthi yonke. Ukuqonda ukusebenza kunye nokusetyenziswa kwemixube eyahlukeneyo kuya kunceda abenzi bezigqibo zobunjineli ukuba bakhethe imixube ngakumbi ngokwesayensi nangengqiqo kwaye bandise usetyenziso lobunjineli

ikhonkrithi esele ixutywe.

Uhlalutyo oluthelekisayo lwemixube eyahlukeneyo kwikhonkrithi esele ilungile:

Isinciphisi samanzi sisidibanisi sekhonkrithi esisele sisetyenziswa ngokuqhelekileyo. Umsebenzi walo oyintloko kukunciphisa ukusetyenziswa kwamanzi kwekhonkrithi ngaphandle kokutshintsha ukuhlukana kunye nokufana kwekhonkrithi, ngaloo ndlela kuphuculwe ukusebenza kunye namandla ekhonkrithi.Ukunciphisa umthamo wamanzi asetyenziswe kwikhonkrithi edibeneyo edibeneyo inempembelelo ebalulekileyo kumgangatho. Impembelelo ephambili kukuphucula amandla ekhonkrithi. Oku kungenxa yokuba umthamo wamanzi ofunekayo kwi-cement hydration reaction iyancitshiswa, ukwenzela ukuba amanzi amaninzi angasetyenziselwa ukuvelisa iimveliso ze-hydration, ngaloo ndlela ukwandisa ukudibanisa phakathi kwamaqhekeza esigaba esiqinileyo kunye nokuphucula amandla. Ukusetyenziswa kokunciphisa amanzi kunokuphucula ukuqina kwekhonkrithi. Iimveliso ezenziwe nge-cement hydration kwikhonkrithi zinokuzalisa ii-pores, ukunciphisa i-porosity, kunye nokunciphisa ukudibanisa kwe-pore, ngaloo ndlela kuphuculwe izikhombisi zokuqina kwekhonkrithi ezifana nokunganyangeki kunye nokuxhathisa iqhwa.
