Ukusetyenziswa kwezixhobo zokunciphisa amanzi, izinto ezithintela ukuguga, kunye nezinto ezikhusela ukwakheka kweplastiki

Izinto zokunciphisa amanzi, izinto ezithintela ukonakala, kunye nezinto ezibangela i-superplasticizers ziikhemikhali ezixutywayo ezisetyenziswa kwi-imixube yekhonkrithiukuphucula iipropati ezithile kunye nokuphucula ukusebenza kwekhonkrithi ngexesha layo elitsha neliqinileyo. Ngayinye kwezi zinto zixutyiweyo isebenzela injongo eyahlukileyo, kwaye zihlala zisetyenziswa kwiiprojekthi zokwakha ukufezekisa iimpawu zekhonkrithi ezifunwayo. Makhe sihlolisise ukusetyenziswa kwezinto zokunciphisa amanzi, izinto ezithintela ukonakala, kunye nezinto ezithintela ukonakala ngakumbi:

1. Izinto zokunciphisa amanzi:

Injongo:

• Ukunciphisa Umthamo Wamanzi: Izinto zokunciphisa amanzi, ezaziwa ngokuba zii-arhente zokunciphisa amanzi okanye iiplastiki, zisetyenziselwa ukunciphisa ubungakanani bamanzi afunekayo kumxube wekhonkrithi ngaphandle kokuphazamisa ukusebenza kwawo.

Iingenelo eziphambili:

• Ukuphucula Ukusebenza: Ngokunciphisa umthamo wamanzi, izixhobo zokunciphisa amanzi ziphucula ukusebenza kakuhle kunye nokuhambelana komxube wekhonkrithi.
• Amandla Aphezulu: Ukuncipha komthamo wamanzi kudla ngokukhokelela ekubeni i-concrete ibe namandla aphezulu kwaye ihlale ixesha elide.
• Ukugqitywa Okuphuculweyo: Ikhonkrithi enezixhobo zokunciphisa amanzi idla ngokuba lula ukuyigqiba, nto leyo ebangela ukuba umphezulu ube bushelelezi.

Izicelo:

• Ikhonkrithi Enamandla Aphezulu: Izinciphisi zamanzi zisetyenziswa kakhulu ekuveliseni ikhonkrithi enamandla aphezulu apho umlinganiselo ophantsi wamanzi nesamente ubalulekile.
• Ukupompa iConcrete: Zenza kube lula ukupompa iConcrete kumgama omde ngokugcina ulwelo luqinileyo.

2. Abaxolisi:

Injongo:

• Ukulibazisa Ixesha Lokuseta: IiRetarders zizinto ezidityanisiweyo ezenzelwe ukunciphisa isantya sokuseta ikhonkrithi, nto leyo evumela ixesha elide lokusebenza.

Iingenelo eziphambili:

• Ukusebenza Kakhulu: Izinto ezigcina izinto zingasebenzi kakuhle zithintela ukumiselwa kwekhonkrithi ngaphambi kwexesha, nto leyo enika ixesha elingakumbi lokuxuba, ukuthutha, kunye nokubeka izinto.
• Ukuqhekeka Okunciphileyo: Amaxesha okubeka izinto kancinci anokunciphisa umngcipheko wokuqhekeka, ingakumbi kwiimeko zemozulu ezishushu.

Izicelo:

• I-Concreting yemozulu eshushu: Kwiimeko apho amaqondo obushushu aphezulu anokukhawulezisa ukumiselwa kwekhonkrithi, izinto ezithintela ukwakhiwa zinceda ekulawuleni ixesha lokumiselwa.
• Iiprojekthi Zokwakha Ezinkulu: Kwiiprojekthi ezinkulu apho ukuthuthwa nokubekwa kwekhonkrithi kuthatha ixesha elide.

3. Izinto ezisebenzisa i-Superplasticizers:

Injongo:

• Ukuphucula Ukusebenza: Ii-Superplasticizers, ezaziwa ngokuba zi-high-range water reducers, zisetyenziselwa ukwandisa ukusebenza kakuhle kwekhonkrithi ngaphandle kokunyusa umthamo wamanzi.

Iingenelo eziphambili:

• Ukusebenza Okuphezulu: Ii-Superplasticizers zivumela ukuveliswa kwekhonkrithi esebenza kakhulu nehambayo enomlinganiselo ophantsi wamanzi nesamente.
• Amandla Anyukileyo: Njengezinto zokunciphisa amanzi, ii-superplasticizers zinegalelo ekuqiniseni i-concrete ngokuvumela umlinganiselo wamanzi nesamente ube sezantsi.

Izicelo:

• Ikhonkrithi Ezicinezelayo (SCC): Ii-Superplasticizers zihlala zisetyenziswa ekuveliseni i-SCC, apho kufuneka khona ukuhamba kwamanzi okuphezulu kunye neempawu zokuzilinganisa.
• Ikhonkrithi Esebenza Kakhulu: Kwizicelo ezifuna amandla aphezulu, ukuqina, kunye nokuncipha kokungena kwamanzi.

Izinto Eziqhelekileyo Omele Uziqwalasele:

1. Ukuhambelana: Izinto ezidityanisiweyo kufuneka zihambelane nezinye izinto ezikumxube wekhonkrithi, kuquka isamente, ii-aggregates, kunye nezinye izongezo.
2. Ulawulo lweMithamo: Ulawulo oluchanekileyo lwemithamo yokuxuba lubalulekile ekufezekiseni iimpawu zekhonkrithi ezifunekayo. Ukusetyenziswa kakhulu kunokukhokelela kwimiphumo emibi.
3. Uvavanyo: Uvavanyo oluqhelekileyo kunye namanyathelo okulawula umgangatho abalulekile ukuqinisekisa ukusebenza kakuhle kwezixube kumxube othile wekhonkrithi.
4. Iingcebiso zoMvelisi: Ukunamathela kwiingcebiso kunye nezikhokelo ezibonelelwa ngumvelisi womxube kubalulekile ukuze kusebenze kakuhle.

Ukuqukumbela, ukusetyenziswa kwezinciphisi zamanzi, izithinteli, kunye nee-superplasticizers kwimixube yekhonkrithi kubonelela ngeenzuzo ezahlukeneyo, ukusuka ekuphuculweni kokusebenza kunye namaxesha okuseta ande ukuya kumandla aphuculweyo kunye nokuqina. Ukuqonda iimfuno ezithile zeprojekthi yokwakha kunye nokukhetha umxube ofanelekileyo okanye indibaniselwano yemixube kubalulekile ekufezekiseni iimpawu zekhonkrithi ezifunekayo. Iidosi zomxube kunye noyilo lwemixube yekhonkrithi kufuneka zicwangciswe ngononophelo kwaye zivavanywe ukuqinisekisa ukusebenza kakuhle kunye nokuqina kwexesha elide kwekhonkrithi.
