Tsis tas li ntawm cov cement grey ib txwm muaj cov cement dawb, uas yog cov khoom siv hauv tsev tshwj xeeb uas muaj nqis rau nws cov xim zoo nkauj thiab kev tsim qauv ntau yam. Nws qhov dawb sib txawv yog los ntawm kev xaiv cov khoom siv raw zoo - cov chaw tsim khoom siv cov limestone ntshiab, av nplaum kaolin, thiab silica nrog tsawg kawg nkaus hlau oxide thiab lwm yam tsis huv uas ua rau muaj xim.
Kev tsim khoom xav tau kev ua kom raug: roj xws li roj av tsis txhob muaj kuab paug, thaum cov khoom siv sib tsoo ceramic lossis pob zeb tiv thaiv kev hloov pauv xim hlau. Tom qab calcination ntawm kwv yees li 1450 ° C los ua clinker, gypsum raug ntxiv ua ntej sib tsoo zoo kom ua tiav qhov dawb xav tau, qib plaub qib.
Txawm hais tias nws cov qauv zoo ib yam li cov cement grey, nws cov kev siv tsis yog tsuas yog kho kom zoo nkauj xwb: txij li cov txheej txheem architectural thiab terrazzo pem teb mus rau cov duab puab thiab cov khoom siv cement xim. Nws kuj ua kom lub zog siv tau zoo dua los ntawm kev cuam tshuam lub teeb thiab ua rau cov xim sib xyaw ua ke rau cov qauv tsim tshwj xeeb. Kev sib xyaw ua ke ntawm kev tshawb fawb thiab kev kos duab, cement dawb txuas ntxiv txhawb nqa lub peev xwm zoo nkauj ntawm kev tsim kho niaj hnub.
