Yenziwe ngantoni ikhonkrithi evuzayo?

I-concrete engapheliyo, eyaziwa ngokuba yi-concrete ye-permeable okanye i-concrete ye-porous, yenziwa ngokusebenzisa umxube we-samente, i-aggregate kunye namanzi, afana nekhonkrithi eqhelekileyo. Nangona kunjalo, ukuze kuphunyezwe ukufikeleleka kwayo, kukho ukungafani okuphawulekayo ekubunjweni kwayo. Umahluko omkhulu kukusetyenziswa kwee-aggregates ezinkulu kunye nokunciphisa inani leengqungquthela ezintle kumxube. Oku kudala izithuba ezinkulu okanye izithuba ngaphakathi kwekhonkrithi evumela amanzi ukuba adlule ngokulula. I-aggregate esetyenzisiweyo inokuba yeentlobo ezahlukeneyo ezifana nelitye elityumkileyo, igrabile okanye i-porous lightweight materials. Ukuqinisekisa ukomelela kunye nokuqina kwekhonkrithi evuzayo, isamente kunye namanzi zihlala ziyizithako ezibalulekileyo. I-samente isebenza njenge-binder yokubamba i-aggregate kunye, ngelixa amanzi eyimfuneko kwi-hydration ngexesha lenkqubo yokunyanga. Ukongeza kwizithako zekhonkrithi ezisemgangathweni, ikhonkrithi engapheliyo inokuthi iqulethe ezinye izongezo okanye izixube. Ezi zongezo zongeza iipropathi zekhonkrithi, ezifana nokwandisa amandla ayo, ukunciphisa iintanda, okanye ukwandisa ukunyanzeliswa kwayo. Eminye imizekelo yezongezo ezisetyenziswa ngokuqhelekileyo kwikhonkrithi ekhoyo ibandakanya umsi wesilica, uthuthu lwempukane, okanye ezinye izinto zepozzolanic. Ezi zixhobo zinceda ukwandisa ukudibanisa ngaphakathi kwe-matrix yekhonkrithi, okubangelwa indawo eqinile kunye neyomelele. Ngokubanzi, ubungakanani obuthile kunye nezinto ezisetyenzisiweyo zinokwahluka ngokuxhomekeke kusetyenziso olucetywayo lwekhonkrithi kunye nokunyanzeliswa okufunekayo. Nangona kunjalo, izithako eziphambili zekhonkrithi evuzayo ziyi-samente, i-aggregate kunye namanzi, kunye nazo naziphi na izongezo eziyimfuneko ezongeziweyo ukuze zifezekise iipropati zayo.

Ukuba unemibuzo ethile okanye iimfuno ezithe ngqo malunga nekhonkrithi evumayo, unokubonisana nomvelisi oyingcali.
