Cov cuab yeej siv tshuab ntawm cement cib tshuab yog lub zog tsav sab nraud. Cov mis uas cuam tshuam qhov zoo ntawm cov khoom cib feem ntau yog cov mis. Los ntawm sib txawv proportions thiab additives, txawv ntsuab zog muaj peev xwm ua tau raws li kev siv sib txawv.

Tsis muaj teeb meem dab tsi ntawm cov cement cib, lub zog yog tsom ntawm cov neeg siv khoom. Cov cement cib thaum ntxov feem ntau muaj cov khoom pov tseg qis sib xyaw, thiab tau poob qhov zoo ntawm kev siv cov peev txheej. Nws yog kom txuag tau cov nqi thiab ntxiv cov khoom siv gel me me, uas tau ua rau qis qis ntawm cov cement cib hauv kev ua lag luam, thiab txawm tias ib zaug raug thuam, uas tau cuam tshuam rau kev ntseeg siab ntawm kev lag luam kev loj hlob. Vim muaj kev sib txawv ntawm cov khoom pov tseg, nws cov mis kuj txawv.

Honcha ua tib zoo txheeb xyuas thiab kawm txog cov qauv thiab kev ua tau zoo ntawm kev tsim cov khib nyiab, thee gangue, ya tshauv, pov tseg pob zeb, steel slag thiab lwm yam khoom pov tseg, kov yeej cov teeb meem, kawm txog cov qauv tsim ntawm cov khoom sib txawv, thiab ua tib zoo mloog cov tswv yim ntawm tus kheej. Tshwj xeeb, raws li cov yam ntxwv ntawm cov khoom pov tseg hauv zos, qhov kev faib ua feem tsim tau muab, thiab cov cuab yeej siv hauv kev tsim cov pob zeb tuaj yeem nqus tau cov khoom pov tseg hauv zos thiab txo cov nqi ntws tuaj yeem kho cov kev ntsuas hauv zos thiab txhim kho cov nqi ntawm cov khoom.

Honcha lub tuam txhab muab cov tswv yim cog kev tsim kho tus kheej rau cov neeg siv khoom. Tom qab ua kom zoo dua qhov kev faib ua feem, kho cov khoom siv ntawm cov cement cib tshuab cov kab ntau lawm, tus nqi raug txo, qhov kev tawm tswv yim-tso tawm piv tau zoo dua, thiab kev lag luam kev sib tw tau txhim kho.
