Qhov tseeb, cov kws tshaj lij, cov neeg ua haujlwm tu, cov neeg ua haujlwm tu, thiab cov thawj tswj hwm ntawm cov tshuab cement cib paub tias kev tswj hwm txoj kev npaj rau cov teeb meem tshwm sim hauv cov tshuab cement cib cia siab rau kev tiv thaiv. Yog tias kev tiv thaiv kev ua haujlwm xws li kev saib xyuas, tshuaj xyuas, thiab kev tshem tawm tau ua tiav, lub tshuab cement cib yuav ua haujlwm zoo. Raws li kev sib tham ntawm cov kws tshaj lij thiab cov kws tshaj lij xws li cov tshuab cement cib thiab cov xim pavement cib tshuab, tsab xov xwm no qhia txog cov kev tiv thaiv nram qab no uas yuav tsum tau xaiv rau cov teeb meem uas muaj feem xyuam rau cov cuab yeej siv tshuab. Kuv vam tias yuav pab tau koj.

Txhawm rau tiv thaiv qhov tshwm sim tsis tu ncua ntawm cov teeb meem tshwm sim hauv cov khoom siv cement cib, nws yog ib qho tsim nyog yuav tsum tau muab qhov tseem ceeb rau cov txheej txheem tswj cov teeb meem. Cov "plaub ntsiab lus" rov hais dua raws li qhov ua tsis tau zoo, uas yog, kev tsom xam teeb meem, kev txhim kho qhov tsis xws luag, kev xa mus rau sab nraud, thiab kev tsim qauv, ua kom muaj kev saib xyuas sai, thiab tswj cov kev ua txhaum ntawm cov tshuab thiab khoom siv.

Tsis tsuas yog cov cement thiab cib tshuab, tab sis kuj tag nrho cov teeb meem tshwm sim thiab nyuaj ntawm cov tshuab cib yuav tsum tau daws sai sai. Raws li plaub lub ntsiab lus ntawm cov phiaj xwm kev tswj hwm qhov teeb meem, ib daim ntawv qhia txog kev txheeb xyuas cov ntaub ntawv teeb meem yuav tsum tau muab tso ua ke. Cov tuam txhab lag luam yuav tsum thov kom cov neeg ua haujlwm txheeb xyuas cov teeb meem sib txawv uas tshaj qhov txawv txav ntau li ntau tau, thiab tsis txhob tshaj tawm sai li sai tau. Tsis tas li ntawd, tsis tu ncua taug qab thiab muab cov lus qhia ntxaws ntxaws txog cov txheej txheem kev tshuaj xyuas cov ntaub ntawv rau cov teeb meem tshwm sim, maj mam txhim kho cov tswv yim thiab kev ua haujlwm zoo, thiab npaj rau qhov thib ob ntawm kev ua haujlwm.

Rau cov cement cib tshuab nrog kev ua haujlwm qis thiab cov teeb meem tshwm sim, nws raug nquahu kom siv cov txheej txheem kev tswj hwm ntawm "kev tshuaj xyuas txhua hnub thiab taug qab los ntawm cov neeg siv khoom siv tshuab", thiab kom tsis txhob sau cov haujlwm. Tsis txhob mus taug qab tsis tu ncua ntawm cov teeb meem tsis sib xws, txhim kho cov phiaj xwm taug qab, thiab ua haujlwm tiv thaiv tus qauv kom txog thaum muaj kev tswj hwm siab tshaj plaws. Qhov no tuaj yeem txo qhov zaus ntawm qee qhov teeb meem ntawm qee lub sijhawm, thiab txhim kho kev ua haujlwm ntawm cov cement cib tshuab.
