Los ntawm qhov kev xav ntawm kev ua haujlwm ntawm cov khoom sib xyaw ua ke, peb tuaj yeem nres kev faib tawm thiab feem ntau kov ntawm plaub yam xwm txheej. Los ntawm kev siv cov khoom sib xyaw ua ke, peb tuaj yeem ua kom tiav kev tswj ntawm pob zeb rheological ceev. Los ntawm kev xav ntawm daim ntawv thov ntawm ntau hom kev sib xyaw ua ke, cov teebmeem kuj txawv. Tom ntej no, cov pob zeb sib xyaw ua ke sib koom ua raws li kev sib xyaw ua ke.
Ntawm lawv, lub luag haujlwm tseem ceeb ntawm tus neeg saib xyuas nag lossis daus yog txo cov dej siv rau kev saib xyuas, muab cov pob zeb ua kom zoo dua qub thiab muaj zog elasticity, thiab txhim kho nws daim ntawv thov ua haujlwm ntev.
Tus neeg saib xyuas huab cua yog kom tsis txhob ntxiv dag zog rau kev solubility ntawm cov pob zeb qis, thiab ua kom tiav cov kev tswj ntawm cov kab nrib pleb sab hauv thiab kev ua kom zoo ntxiv ntawm permeability los ntawm kev hloov kho ntawm cov pob zeb sab hauv.
Tsis tas li ntawd, ntau daim ntawv thov pob zeb muaj qhov xav tau siab rau impermeability. Cov neeg yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua los ntawm kev siv cov neeg ua haujlwm siab los nag lossis daus los txhim kho qhov ntom ntom ntawm cov pob zeb. Tsis tas li ntawd, qhov kev txhim kho hauv cov pob zeb yog qhov ua rau corrosion, thiab cov neeg ua haujlwm cuam tshuam tuaj yeem tswj cov carbonation ntawm cov pob zeb nrog kev pab ntawm daim ntawv thov ntawm nag lossis daus tus neeg sawv cev.Yog tias tus nqi pH hauv cov pob zeb qhia tau hais tias qhov kev poob qis, qhov teeb meem steel bar xeb kuj tseem yuav tiv thaiv ntau yam.
Vim muaj ntau yam sib txawv, kev xaiv ntawm cov khoom sib xyaw ua ke tseem yuav pom qhov sib txawv pom tseeb. Txhawm rau ua kom pom cov txiaj ntsig ua haujlwm tau zoo, cov neeg ua haujlwm cuam tshuam yuav tsum tau tso tseg qhov kev tswj xyuas tsim nyog ntawm kev faib ua feem ntawm cov khoom sib txawv los ntawm cov yam ntxwv sib txawv, thiab tswj kom muaj kev txhim kho zoo ntawm kev ua tau zoo ntawm pob zeb nws tus kheej. Ntawm, dej-txo tus neeg sawv cev yog ib qho kev sib xyaw ua ke uas tuaj yeem txo cov dej sib xyaw ua ke nyob rau hauv cov xwm txheej uas cov slump ntawm pob zeb yog qhov tsis hloov pauv. Tom qab ntxiv cov pob zeb sib xyaw, nws tuaj yeem tawg cov cement hais, txhim kho nws cov haujlwm ua haujlwm, txo cov dej siv dej, thiab txhim kho cov dej ntws ntawm cov pob zeb sib xyaw; Los yog txo cov cement noj kom txuag tau cov cement.
