Ukuthuthukisa ukhonkolo ngezithasiselo

Ukuthuthukisa ukhonkolo nezithasiselo kufaka ukufaka izengezo ezahlukahlukene zamakhemikhali kanye namaminerali ku-conkcrete mix ukuze uthuthukise izakhiwo noma izici ezithile zokhonkolo onzima. Nazi izinhlobo eziningana zezengezo ezisetshenziselwa ukuthuthukisa ukhonkolo:

1. Ukunciphisa ama-admixtures amanzi (amapulasitiki):
   • Ukunciphisa ama-admixtures anciphise amanzi, eyaziwa nangokuthi amapulasitiki noma ama-superplastifizer, athuthukise ukukhiqizwa ngokunciphisa inani lamanzi adingekayo ku-conkcrete mix. Basiza ukukhuphula ukuncipha, banciphise ukwahlukaniswa, futhi bathuthukise ukugeleza kokhonkolo ngaphandle kokuyekethisa amandla.
2. Setha ukubuyisa ama-admixtures:
   • Setha i-Retarding OmustardTures isetshenziselwa ukubambezela isikhathi sokusetha ukhonkolo, okuvumela ukukhiqizwa okunwetshiwe kanye nesikhathi sokubekwa. Zilusizo ikakhulukazi ezimweni zezulu ezishisayo noma kumaphrojekthi amakhulu lapho kutholakala khona izinto zokuhamba nezikhathi zokubekwa.
3. Setha ukusheshisa ama-admixtures:
   • Setha ukusheshisa ama-advixtures asetshenziselwa ukusheshisa isikhathi sokhonkolo, ukunciphisa isikhathi sokwakha kanye nokunika amandla ukususwa kwemali okusheshayo nokuqeda. Zinenzuzo ezimweni zezulu ezibandayo noma lapho kudingeka khona amandla okuqina okusheshayo.
4. Ama-admixtures afaka umoya:
   • I-admixtures efaka umoya ingezwa kukhonkolo ukudala ama-bubble e-microscopic in the ukuxubana, okuthuthukisa ukumelana nokuqina kwe-freeze-thaw nokuqina. Bathuthukisa ukusebenziseka kanye nokuhlangana kokhonkolo, ikakhulukazi ezimweni sezulu ezinokhahlo.
5. Ama-Pozwolans:
   • Izinto ze-pozzolanic ezinjenge-fly ash, i-silica fuumu, futhi i-slag yizengezo zamaminerali ezisabela nge-calcium hydroxide ku-cement ukwakha amanye amakhompiyutha angeziwe. Bathuthukisa amandla, ukuqina, kanye nokumelana nokuhlaselwa kwamakhemikhali futhi banciphise ukushisa kwe-hydration.
6. I-Fibers:
   • I-Fibre Additives, njengensimbi, zokwenziwa (i-polypropylene, i-nylon), noma imicu yengilazi, isetshenziselwa ukuthuthukisa amandla ashukumisayo, ukumelana nomthelela, kanye nokhuni lukakhonkolo. Basiza ukulawula ukuqhekeka futhi bathuthukise ukuqina kwezicelo ezihlelekile nezesakhiwo.
7. I-Shrinkage-encishise ama-admixtures:
   • I-Shrinkage-Reacucing admixtures isetshenziselwa ukunciphisa ukumiswa kwe-shrinkage ngokhonkolo, kunciphisa ubungozi bokuqhekeka nokwenza ngcono ukuqina kwesikhathi eside. Basebenza ngokunciphisa ukungezwani kwamanzi okuxubana ngokhonkolo.
8. I-Corrosion inhibitors:
   • I-Corovion inhibitors iyizengezo zamakhemikhali ezivikela eziqinisiwe eziqinisweni kokhonkolo ezibangelwa i-chloride ion, i-carbonation, noma ezinye izinto ezinolaka. Basiza ukunweba impilo yenkonzo kakhonkolo ezindaweni zasemanzini, ezimbonini, noma ezinkulu.
9. Ama-ejenti wokufaka imibala:
   • Ama-ejenti anemibala, njengezimbali ze-Iron oxide noma udayi wokwenziwa, asetshenziselwa ukwengeza umbala kukhonkolo ngezinhloso zokuhlobisa noma zobuhle. Bathuthukisa isikhalazo esibonakalayo sendawo yokhonkolo ezisetshenzisweni zezakhiwo kanye nezokubuka emhlabeni.

Ngokufaka lezi zithasiselo ezixukwini ukhonkolo, onjiniyela kanye nosonkontileka bangavumelanisa nezici zikakhonkolo ukuze bahlangabezane nezidingo ezithile zephrojekthi futhi bazuze izici zokusebenza, ezinjengamandla, ukuqina, ukusebenziseka nokubukeka.
