Superplasticizer yog hais txog cov xwm txheej uas ua kom cov pob zeb poob qis ib yam nkaus,

Admixtures uas tuaj yeem txo cov dej siv hauv kev sib tov zoo heev.Lub High Performance Water Reducer yog lub tswv yim tshiab uas tau npaj tseg tom qab lub tswv yim ntawm kev ua haujlwm siab ua vaj tse.Tam sim no, nws tsis tau txhais meej meej.Nws feem ntau yog hais txog kev sib xyaw ua ke nrog cov dej txo qis thiab kev ua haujlwm poob qis uas muaj cua induction.Txawm li cas los xij, los ntawm kev nkag siab thiab kev siv ntawm polycarboxylic acid thiab lwm yam carboxylic acid superplasticizers nyob rau hauv lub ntiaj teb pob zeb ua teb nyob rau hauv xyoo tas los no, hom superplasticizer no kuj muaj cov yam ntxwv hauv qab no.

(1) Cov ntsiab lus tsawg thiab cov dej txo qis (cov ntsiab lus feem ntau yog 0.05% -0.5% ntawm cov ntsiab lus binder, thiab cov dej txo qis tuaj yeem ncav cuag 35% -50%, lossis ntau dua);

(2) Tsis muaj kev sib cais, tsis muaj los ntshav, kev ua haujlwm ntawm kev ua kom cov pob zeb tawg yog qhov zoo dua, tuaj yeem ua tsis pub dhau 120min yeej tsis poob;

(3) tuaj yeem npaj super siab zog thiab super durability pob zeb;

(4) Zoo sib xws nrog cov cement, admixture thiab lwm yam khoom siv;

(5) Nws tuaj yeem txo qhov kub ntawm adiabatic thaum ntxov ntawm cov pob zeb, uas yog qhov zoo dua rau cov pob zeb loj;(6) Kev ywj pheej ntau dua nyob rau hauv cov qauv molecular, muaj peev xwm ua kom muaj kev ua tau zoo ntawm cov dej txo tus neeg sawv cev;

(7) Vim hais tias cov synthesis tsis siv formaldehyde thiab lwm yam khoom ua paug ib puag ncig, nws muaj txiaj ntsig zoo rau kev tsim kho kom ruaj khov ntawm kev lag luam;(8) Nws muab kev lees paub rau kev txhawb nqa kev siv cov khoom siv pov tseg xws li ya tshauv, slag thiab steel slag.

Nws tuaj yeem pom tias polycarboxylic acid series ntawm kev ua haujlwm siab superplasticizer yuav tsum tau ua kom tau raws li lub xyoo pua 21st pob zeb ua haujlwm siab heev.
