Imixube edla ngokusetyenziswa ekwakhiweni kodaka oluxutyiweyo olomileyo
Udaka oluxutyiweyo luhlobo lwemathiriyeli yokwakha esetyenziswa kakhulu kwiiprojekthi zokwakha ezahlukeneyo.Ngumxube wesamente, isanti, kunye nezinye izongezo ezixutywa kwangaphambili phambi kokusetyenziswa.Enye yezona zinto zibalulekileyo zodaka oluxubeneyo oluxubileyo kukusetyenziswa kwe-admixtures, ephucula ukusebenza kodaka kwaye yenze ukuba ifaneleke ngakumbi kwizicelo ezithile.Kweli nqaku, siza kuxubusha ezinye ze-admixtures eziqhelekileyo ezisetyenziswa kwi-dry-mixed mortar.
1. Iiarhente ezibuyiswayo
Ii-agent ezibuyiswayo zisetyenziselwa ukucotha ixesha lokumisela udaka oluxutywe ngoomileyo.Oku kuvumela abasebenzi ixesha elingakumbi lokusebenza ngodaka kwaye kuqinisekisa ukuba lunokusetyenziswa ngokufanelekileyo.Ii-agent ezibuyiswayo ziluncedo ngokukhethekileyo kwiimeko zemozulu ezishushu, apho ukubeka ngokukhawuleza udaka kunokuba yingxaki.
2. Iiarhente zokukhawulezisa
I-Accelerating agents, ngakolunye uhlangothi, ikhawuleza ixesha lokumisela udaka oluxubekileyo.Zihlala zisetyenziswa kwiimeko ezibandayo zemozulu, apho ukuseta kancinci kodaka kunokuba yingxaki.Zingaphinda zisetyenziswe kwiimeko zokulungisa ngokukhawuleza, apho udaka olukhawulezayo lufuneka ukulungisa ingxaki.
3. Iiarhente zokungenisa umoya
Iiarhente zokungenisa umoya zisetyenziselwa ukwenza amaqamza amancinci omoya eludaka.La maqamza aphucula ukusebenza kunye nokuqina kodaka ngokwenza ukuba luxhathise ngakumbi imijikelo yokunyibilika komkhenkce kunye nokunciphisa umngcipheko wokuqhekeka.Ii-agent zokungenisa umoya zihlala zisetyenziselwa kwiindawo ezineemeko ezinzima zasebusika, apho udaka luya kubonakaliswa kwimijikelezo ye-freeze-thaw.
4. Iiarhente zokunciphisa amanzi
Iiarhente zokunciphisa amanzi zisetyenziselwa ukunciphisa umthamo wamanzi afunekayo ukuxuba udaka.Oku kwenza udaka lomelele kwaye lomelele ngakumbi, njengoko amanzi amaninzi enokuwenza buthathaka imveliso yokugqibela.Iiarhente zokunciphisa amanzi nazo zenza ukuba udaka lusebenze ngakumbi, olunokuphucula umgangatho opheleleyo wemveliso egqityiweyo.
5. Iiarhente zeplastiki
Ii-agent zeplastiki zisetyenziselwa ukwenza udaka lube bhetyebhetye kwaye lusebenze.Baphucula iimpawu zokubambisana zodaka kwaye zenze kube lula ukuzisebenzisa kwiindawo ezahlukeneyo.Ii-agent ze-Plasticizing ziluncedo ngakumbi kwiimeko apho udaka luya kusetyenziswa kwiindawo ezingaqhelekanga okanye kwiindawo apho kulindeleke khona ukuhamba.
6. Ii-Anti-cracking agents
Ii-anti-cracking agents zisetyenziselwa ukuthintela udaka ekuqhekekeni njengoko loma.Banceda ekuphuculeni ukuqina kunye nexesha elide lodaka ngokunciphisa umngcipheko wokuqhekeka.Ii-Anti-cracking agents zihlala zisetyenziselwa kwiindawo ezinezinga eliphezulu lomsebenzi we-seismic, apho udaka luya kuba phantsi kwee-vibrations ezinamandla kunye nokunyakaza.
I-Admixtures idlala indima ebalulekileyo ekusebenzeni kunye nomgangatho wodaka oluxutyiweyo.Ukusetyenziswa kwezi zidibanisi kunokuphucula ukusebenza, amandla, ukuqina, kunye nomgangatho opheleleyo wemveliso egqityiweyo.Ngokuqonda iintlobo ezahlukeneyo zemixube ekhoyo, iingcali zokwakha zinokukhetha ii-admixtures ezifanelekileyo kwiiprojekthi zabo ezithile kwaye ziqinisekise iziphumo ezilungileyo.
