Tom qab siv admixture, peb tuaj yeem tau txais ntau qhov txiaj ntsig kev lag luam thiab nyiaj txiag, xws li txuag cov cement, txuag hluav taws xob, ua kom muaj zog, ua kom lub sijhawm luv, ua kom sai ntawm formwork thiab precast site turnover, txhim kho pob zeb ua kom zoo dua qub thiab txhim kho kev ua haujlwm tsim kho.
Kev tsim kho lub ntsiab ntawm cov qhob kev tshawb fawb thiab thev naus laus zis yog txuag hluav taws xob, kav ntev, siab zog, lub teeb nyhav, yoo tawv thiab muaj lub siab dua.Qhov ua tiav ntawm cov hom phiaj no feem ntau ze rau kev siv admixtures.Qhov nrov thiab daim ntawv thov ntawm pob zeb ua admixtures yog qhov kev sib tw tseem ceeb hauv keeb kwm ntawm cov ntawv thov cov cement.
Kev ua vaj tse yog ib hom kev muaj peev xwm dav dav, muaj ob pua xyoo keeb kwm ntawm cov ntaub ntawv ib txwm muaj, cov pob zeb ua tau siv dav hauv cov huab siab siab ntawm cov tsev siab, kev tsim cov choj ntev, kev txuag dej lub pas dej tauv thiab cov chaw tsim khoom siv tub rog thiab kev tsim kho vaj tse xws li nuclear reactor, qhov kawg ntawm lub ntiaj teb muaj qhov muaj cov pob zeb ua, pob zeb tshiab thiab kev tsim kho tshuab tshiab, qhov yuav tsum tau ua cov pob zeb nrog kev teeb tsa tau kho, thaum ntxov muaj zog, siab zog, tsis muaj peev xwm kub, tsis muaj fluidity, lub teeb yuag, tsis tshua muaj brittleness thiab siab ntev. yuav tsum, nyob rau tib lub sijhawm rau kev npaj ntawm kev siv hluav taws xob tsawg, kev siv nyiaj tsawg thiab haum rau kev tsim kho nrawm nrawm thiab cov yam ntxwv ntawm kev lag luam zoo.Qhov saum toj no - hais txog cov khoom siv thiab paub cov txheej txheem cov txheej txheem, yog sib cais los ntawm cov vaj tse admixture.Ntawm no, qhob admixture tau dhau los ua qhov tsis tseem ceeb thib tsib ntawm cov pob zeb ua tsuas yog cov cement, xuab zeb, pob zeb thiab dej.
Nrog cov kev txhim kho txuas ntxiv ntawm kev tsim kho, pob zeb (pob zeb) yog siv ntau thiab ntau dua, thiab cov kev ua haujlwm ntawm cov pob zeb ua (pob zeb) yog xav tau ntau dua thiab xav tau thiab ntau dua, ntawm cov txheej txheem admixture los txhim kho kev ua haujlwm ntawm cov pob zeb ua (pob zeb) yog ib qho ntawm cov qauv yooj yim thiab zoo tshaj plaws.Hauv cov khoom siv dav siv hauv cov teb chaws nyob hauv ntiaj teb, yuav luag 100% ntawm cov pob zeb ua siv admixtures.Admixture tsis muaj admixture pom tau tias yog ib qho pov tseg hnyav, admixture belongs rau cov khoom siv txuag hluav taws xob.
