Cov neeg ua vaj tse pob dej-txo tus neeg ua haujlwm tau dhau los ua cov tseem ceeb hauv kev npaj cov pob zeb ua niaj hnub no thiab kev siv thev naus laus zis. Daim ntawv thov ntawm ntau lub admixtures yog ib qho kev ntsuas tseem ceeb los ua cov khoom siv pob zeb ua tiav kev ua tiav siab thiab ntsuab.Qhov kev npaj tus neeg los cuam tshuam nrog txhua cov pob ntawm cov cement, txhua cov kev ntsuas kom zoo thiab kuaj nrog cov pob zeb ua admixture, cov yam ntxwv ua haujlwm rau cov khoom siv raw, raws li qhov ua tau kom muaj kev sib nrig sib cuam tshuam zoo admixture thiab xis mas, thiaj li yuav zam tau cov kev siv ntau yuav tsis hloov rau cov cement thiab admixture los ua qhov zoo sib tsoo, cov khoom pov tseg lossis tus nqi nce ntxiv.
Hauv kev siv engineering, kev ntsuam xyuas kev hloov kho ntawm cov cement thiab pob zeb ua cov dej tsim ua kom tiav yuav tsum ua tiav ua ntej kev npaj cov pob zeb sib tov, yog li kom raug xaiv cov xis mas, admixture thiab admixture, thiab txiav txim siab qhov sib piv.
Hauv kev tsim kho, cog tsev cog khoom thiab cov khoom cog ntxiv yuav tsum muaj cov khoom lag luam zoo ruaj khov.Yog hais tias cov pob zeb los yog cov khoom thaiv pom cov teeb meem tsis sib xws, yuav tsum koom tes nrog kev txheeb xyuas tam sim thiab nrhiav qhov laj thawj, thiaj li nrhiav kev tawm tsam.
