(1) Xaiv hom kev xaiv dej-txo tus neeg saib xyuas
Kev xaiv ntawm cov dej tso tawm tus neeg sawv cev yuav siv dej txo tus nqi, dej khaws cia thiab yas khaws cia raws li lub ntsiab index.On qhov ua ntej tsis nce cov dej noj, admixture yog qhov kev xaiv zoo tshaj plaws los ua kev lag luam ua vaj tse muaj cov khoom ntawm kev poob qis, tsis muaj kev sib cais, tsis muaj los ntshav, plam me ntsis poob thiab lwm yam.
(2) Tsim nyog txiav txim siab pom qhov muaj txiaj ntsig zoo tshaj plaws ntawm cov dej-txo tus neeg sawv cev
Qhov zoo tshaj plaws ntawm admixture hais txog tus nqi ntawm cov dej txo admixture txiav txim siab los ntawm kev kuaj pob zeb.Yog lub tsev ua haujlwm ntawm kev ua tiav cov kev xav tau ntawm kev ua vaj tse, cov ntsiab lus tsawg dua, kev lag luam tsawg dua nws yog.Qhov tseem ceeb uas txiav txim qhov ntau npaum suav nrog hom dej reducer, lub hom phiaj ntawm dej reducer daim ntawv thov, hom ntawm cov cement, qhov muaj pes tsawg leeg thiab kev faib ua feem ntawm cov pob zeb, cov nqi ntawm cov cement ib chav tsev, thiab lwm yam ntxiv thiab, cov khoom sib xyaw kuj cuam tshuam rau ntau qhov ntxiv.Qhov cement superplasticizer nrog siab saum npoo thiab siab C3A cov ntsiab lus yuav tsum muab sib xyaw nrog ntau dua.
(3) Siab txiav txim siab cov bidirectional adaptability ntawm admixture thiab xis mas
Lub bidirectional kev hloov kho ntawm cov cement thiab admixture txhais tau tias nyob rau hauv kev teeb tsa ntawm pob zeb ua, tsis tsuas yog cov admixture yuav tsum tau hloov kho rau cov cement, tab sis kuj tseem muaj cov cement yuav tsum yoog rau admixture los ntawm kev kho nws cov clinker ntxhia, ua kom zoo thiab particle gradation.Only thaum ob qhov kev tsim kho txhua tus tuaj yeem ua cov pob zeb nrog kev ua tau zoo thiab kev tsim kho yooj yim.
