Concrete admixture yog taw tes rau kev sib xyaw hauv cov txheej txheem ntawm kev ua vaj tse sib xyaw txhawm rau txhawm rau txhim kho kev ua tau zoo ntawm cov khoom siv, nws cov khoom sib xyaw feem ntau tsis ntau dua li cov cement zoo 5 feem pua (tshwj tsis yog rau qhov xwm txheej tshwj xeeb). Concrete admixtures tsis suav nrog cov ntaub ntawv, gypsum thiab sib tsoo AIDS ntxiv rau kev tsim cov cement, thiab txawv ntawm cov khoom siv ntxiv rau cov pob zeb sib xyaw. Txawm hais tias tus nqi ntawm cov pob zeb sib xyaw yog me me, nws tuaj yeem txhim kho kev ua haujlwm ntawm cov pob zeb sib xyaw, txhim kho lub cev thiab cov khoom siv dag zog thiab ua kom ntev ntawm cov pob zeb, thiab ua tiav cov txiaj ntsig zoo tshaj plaws thiab kev lag luam.
Admixtures nyob rau hauv daim ntawv thov ntawm niaj hnub pob zeb tau dhau los ua ntau thiab ntau, txhawb txoj kev loj hlob ntawm cov pob zeb ntau lawm thiab kev tsim kho technology thiab cov pob zeb tshiab, uas ua rau peb lub kiv puag ncig ntawm pob zeb technology, tau dhau los ua ntxiv rau cement, xuab zeb, pob zeb thiab dej thiab lwm yam. cov ntsiab lus tseem ceeb ntawm pawg tsib ntawm cov ntsiab lus, dhau los ua cov xwm txheej tsim nyog rau kev npaj cov kev ua tau zoo ntawm cov pob zeb.
