Kev tsim cov hollow block, unburned cib thiab lwm yam khoom siv hauv tsev tshiab los ntawm kev lag luam pov tseg tau coj txoj hauv kev loj hlob thiab kev lag luam dav dav. Txhawm rau txhawb kev tsim cov khoom siv phab ntsa tshiab los hloov cov av nplaum cib thiab txhawb kev siv dav ntawm cov khoom siv khib nyiab.

Ua ntej tshaj plaws, kev tiv thaiv ib puag ncig, cov khoom siv raw siv los ntawm cov av nplaum cib tshuab yog qhov kev puas tsuaj loj rau ib puag ncig los ntawm cov mining hauv zos thiab khawb, thiab cov cement cib tshuab muaj qee yam zoo rau kev tiv thaiv ib puag ncig.
Qhov thib ob, tus nqi qis dua av nplaum cib

Txhua yam cement cib thiab av nplaum cib tsim los ntawm hom cib tshuab no muaj ib tus cwj pwm sib txawv. Lawv yog cov hauv paus tag nrho cov tsev uas tsim los ntawm cov cement cib tshuab, thiab siv cov squares loj hauv tsev kawm ntawv.

Yog li ntawd, hydraulic cement cib tshuab tuaj yeem ua tau zoo los ntawm cov neeg siv khoom. Honcha block ua machinery yog cov chaw tsim khoom tshwj xeeb hauv kev tsim khoom thiab kev tsim cov tshuab ua haujlwm puv-automatic cement cib. Peb kuj tsim qee cov cuab yeej txhawb nqa rau cement cib tshuab, thiab peb kuj tsim pwm rau cov neeg siv khoom.
