Qhov ntau npaum ntawm polycarboxylic acid superplasticizer yuav tsum tau txiav txim siab los ntawm kev sim ua ntej raws li tus neeg siv khoom noj pom zoo, kev siv cov khoom, kev tsim kho, kev ua vaj tsev, pob zeb ua raw khoom thiab lwm yam.
Cov khoom tseem ceeb thiab cov tsis muaj ntawm polycarboxylic acid superplasticizer:
1. Qhov ntau npaum li cas yog 0.5% ~ 1% ntawm qhov hnyav ntawm cov cement, thiab dej txo tus nqi tuaj yeem ncav cuag 12% ~ 25%;
2. Lub zog thaum ntxov nce sai, 1 ~ 3 hnub tshaj li lub zog ntawm cov qhob dawb tuaj yeem nce ntau dua 60%;
3. Qhov ua kom zoo dua qhov pom tseeb yog pom tseeb, 28-hnub lub zog tuaj yeem nce ntxiv 15% ~ 40% ntau dua li cov pob zeb dawb;
4. Thaum tus nqi ntawm cov cement yog tib yam thiab lub zog yog zoo ib yam, cov nqes tau tuaj yeem nce los ntawm 100 ~ 200 hli;
5. Raws li cov xwm txheej ua haujlwm thiab lub zog ntawm cov pob zeb ua haujlwm zoo sib xws, 10% ~ 20% ntawm cov cement yuav txuag tau;
6. Super sib xyaw txoj kev yog saws, C (60) ~ C (80) qhob (1% ~ 2%) tuaj yeem tsim kho.
