Ukuphucula iConcrete ngeeAdditives

Ukuphucula ikhonkrithi ngezithako zokongeza kubandakanya ukufaka izongezo ezahlukeneyo zeekhemikhali kunye neeminerali kumxube wekhonkrithi ukuphucula iimpawu ezithile okanye iimpawu zekhonkrithi eqinileyo. Nazi iintlobo ezahlukeneyo zezongezo ezisetyenziswa rhoqo ukuphucula ikhonkrithi:

1. Izinto zokunciphisa amanzi (iiplastiki):
   • Izinto ezidityanisiweyo ezinciphisa amanzi, ezaziwa ngokuba ziiplasticizers okanye iisuperplasticizers, ziphucula ukusebenza ngokunciphisa ubungakanani bamanzi afunekayo kumxube wekhonkrithi. Zinceda ekwandiseni ukuhla, ukunciphisa ukwahlulwahlulwa, kunye nokuphucula ukuhamba kwamanzi kwekhonkrithi ngaphandle kokunciphisa amandla.
2. Seta Izixube Ezibuyela Umva:
   • Izixube ezibambezelayo zeseti zisetyenziselwa ukulibazisa ixesha lokuseta i-concrete, okuvumela ukuba isebenze ixesha elide kwaye ibekwe. Ziluncedo ngakumbi kwiimeko zemozulu ezishushu okanye kwiiprojekthi ezinkulu apho kufuneka ixesha elide lokuthuthwa kunye nexesha lokubeka.
3. Seta ii-Admixtures ezikhawulezisayo:
   • Izixube ezikhawulezayo zeseti zisetyenziselwa ukukhawulezisa ixesha lokuseta ikhonkrithi, ukunciphisa ixesha lokwakha kunye nokwenza kube lula ukususa nokugqiba iifomwork ngokukhawuleza. Ziluncedo kwiimeko zemozulu ebandayo okanye xa kufuneka ukomelezwa ngokukhawuleza.
4. Izixube zokungenisa umoya:
   • Izinto ezidityanisiweyo zomoya zongezwa kwikhonkrithi ukuze kudalwe amaqamza omoya amancinci kumxube, nto leyo ephucula ukumelana nokunyibilika komkhenkce kunye nokuqina. Ziyandisa ukusebenza kunye nokudibana kwekhonkrithi, ngakumbi kwiimeko zemozulu ezinzima.
5. IiPozzolans:
   • Izinto ezibizwa ngokuba yi-pozzolanic ezifana nothuthu oluphuma kwi-fly ash, i-silica fume, kunye ne-slag zezona zinto zisetyenziswa njengezongezo zezimbiwa ezisabela kwi-calcium hydroxide kwisamente ukuze zenze ezinye izinto ezidityanisiweyo nesamente. Ziphucula amandla, ukuqina, kunye nokumelana nokuhlaselwa ziikhemikhali kwaye zinciphisa ubushushu bokufuma.
6. Iifayibha:
   • Izongezo zefayibha, ezifana nentsimbi, izinto ezenziwe ngokwenziwa (i-polypropylene, i-nylon), okanye iifayibha zeglasi, zisetyenziselwa ukomeleza amandla okutsalwa, ukumelana nempembelelo, kunye nokuqina kwekhonkrithi. Zinceda ekulawuleni ukuqhekeka kunye nokuphucula ukuqina kwizicelo zesakhiwo kunye nezingezizo izakhiwo.
7. Izixube Ezinciphisa Ukushwabana:
   • Izixube ezinciphisa ukushwabana zisetyenziselwa ukunciphisa ukushwabana kokoma kwikhonkrithi, ukunciphisa umngcipheko wokuqhekeka nokuphucula ukuqina kwexesha elide. Zisebenza ngokunciphisa uxinzelelo lomphezulu wamanzi kumxube wekhonkrithi.
8. Izithinteli zokuGqobhoka:
   • Izithinteli zokubola zizinto ezongeziweyo zeekhemikhali ezikhusela izakhiwo zekhonkrithi eziqinisiweyo ekuboleni okubangelwa yi-ion ye-chloride, i-carbonation, okanye ezinye izinto ezirhabaxa. Zinceda ekwandiseni ubomi benkonzo yekhonkrithi kwiindawo zaselwandle, kwimizi-mveliso, okanye kwiindlela ezinkulu.
9. Iiarhente zokufaka imibala:
   • Izinto zokufaka imibala, ezifana nee-iron oxide pigments okanye iidayi ezenziwe ngokwenziwa, zisetyenziselwa ukongeza umbala kwikhonkrithi ngeenjongo zokuhombisa okanye zobuhle. Ziyandisa ukubonakala komphezulu wekhonkrithi kwizicelo zokwakha kunye nokulungisa umhlaba.

Ngokufaka ezi zongezo kwimixube yekhonkrithi, iinjineli kunye nabakhi banokulungisa iipropati zekhonkrithi ukuze zihlangabezane neemfuno ezithile zeprojekthi kwaye zifezekise iimpawu zokusebenza ezinqwenelekayo, ezinje ngamandla, ukuqina, ukusebenza kakuhle, kunye nembonakalo.
