Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
Sisebenzisa imixube yeekhemikhali ekulungiseleleni ikhonkrithi kunye nee-aggregates kunye namanzi ukuguqula iipropati ezahlukeneyo zekhonkrithi njengokwandisa ukusebenza., ukunciphisa ukucutheka kunye nomhlwa, faka amaqamza amancinci kwikhonkrithi, ukukhawulezisa okanye ukurhoxisa inkqubo yokuqina kunye nezinye ezininzi. Ezi zidibaniso zongezwa kwimilinganiselo emincinci kwaye zinokwenza ukwakhiwa kuqoqosho ngakumbi kwaye kube lula ukugqitywa.
Iisuperplasticizer zekhonkrithi eziqhelekileyo ezisetyenziswayo namhlanje ziyipolycarboxylate (PCE) iiarhente zokunciphisa amanzi. I-PCE ngumxube oguquguqukayo kakhulu kwaye iikhemisti ziyaqhubeka nokukhohlisa ubume bayo bepolymer ukunika amandla athile kwimixube yekhonkrithi..
Nje, Ii-PCEs zinokongezwa kwi-concrete ye-w / c ephantsi kunye namaxesha amafutshane okuxuba kunye nokuvumela ukugcinwa kwe-slump ixesha elide.. Olu phawu lubenza lube lulungele ukulungelelaniswa kwezicelo zekhonkrithi apho umgangatho wekhonkrithi, ngakumbi ugcino lokuthotywa lubalulekile.
Olunye uncedo lwee-PCEs kukuba zinokusetyenziswa kunye nothuthu lwempukane kunye nezinye izinto ezithatha indawo yesamente. Oku kuluncedo kakhulu kwimimandla apho iinkxalabo zokusingqongileyo kunye neendleko zixhalabisayo kuba zivumela ubuninzi bezinto ezibuyiselweyo ukuba zisetyenziswe ngaphandle kokuncama amandla okanye ukusebenza.. Bakwabonelela nangezinye iingenelo zokusebenza ezifana nokomeleza amandla okuqala, ukunciphisa ukunyanzeliswa kunye nokuchasana okulungileyo kwi-ion ye-chloride kunye ne-alkali.
