Nyob rau hauv cov ntsiab lus ntawm kev tsim kho vaj tse loj, kev ua haujlwm siab ua vaj tse tau nthuav dav thoob plaws lub ntiaj teb vim nws cov dej khov zoo, impermeability, carbonation tsis kam, shrinkage resistance, workability thiab durability, uas tau ua raws li cov kev xav tau ceev ntawm lub teb chaws. engineering kev tsim kho. Txawm li cas los xij, nyob rau hauv kev siv tiag tiag ntawm cov pob zeb ua haujlwm siab, tib neeg pom tias ntxiv rau kev ua haujlwm zoo, nws cov durability, impermeability tsis tau txhim kho, tshwj xeeb tshaj yog cov kab nrib pleb kuj muaj qee qhov kev poob qis.
Kev ua haujlwm siab ua vaj tse hauv qhov av, choj, dej txuag dej, tshav dav hlau khiav, lub sijhawm tsim tsev siab, kev lag luam thiab kev hloov pauv ib puag ncig tau pom tias muaj txiaj ntsig zoo, tab sis qee qhov kev tsim vaj tsev yuav tshwm sim sib txawv ntawm kev tawg, rau peb cov neeg tsim khoom, qhov no yog ib qho teeb meem ceev uas yuav tsum tau daws.
Tsis tas li ntawd, txij li cov hmoov tshauv ya tau ntxiv rau cov pob zeb ua cov ntxhia ntxiv, cov tuam txhab kev lag luam ua vaj tse txuas ntxiv tsim cov tshiab ntawm cov ntxhia ntxiv, xws li slag, ntau yam tailings, limestone hmoov, thiab lwm yam., ntau yam ntau yam, ntau npaum li cas. nce loj heev. Kev siv cov khoom sib xyaw no hloov cov khoom pov tseg rau hauv cov khoom siv raw, ua tiav cov txiaj ntsig ntawm kev rov ua dua tshiab. Txawm li cas los xij, peb kuj yuav tsum pom tias qhov sib ntxiv ntawm cov khoom sib xyaw kuj tseem yuav ua rau kom cov pob zeb tawg.
