Thib ob, kev tsim kho ntawm cov khoom siv dag zog muab cov peev txheej tshiab rau kev tsim khoom thiab kev siv cov xiav marble slabs. Los ntawm kev siv cov khoom siv raw thiab cov txheej txheem sib txawv, cov khoom siv marble tuaj yeem tsim tau zoo ib yam li lossis zoo dua li ntuj marble. Piv txwv li, khoom kim heev-xim xim marble siv siab alumina cement, Portland cement, thiab lwm yam raws li cov ntaub ntawv raw thiab ua tiav thiab tsim hauv ib qho mus. Nws muaj zoo compressive thiab flexural zog thiab durability.
. Tsis tas li ntawd, kev tshawb fawb ntawm tag nrho lub cev marble vuas tau pom tias los ntawm kev tswj cov xwm txheej xws li kev npaj cov hmoov thiab hluav taws kub, ruaj khov ntawm cov vuas marble tuaj yeem ua tiav thiab tus nqi ntawm cov khoom zoo tuaj yeem nce ntxiv.

Tsis tas li ntawd, txawm hais tias cov khoom siv dag zog muaj ntau qhov zoo, xws li hnav tsis kam, hnav, thiab zoo nkauj tsos, nws txoj kev lag luam tseem ntsib qee qhov kev sib tw, suav nrog cov khoom tsis sib xws thiab tsis muaj cov cuab yeej technology.

Yuav kom suav tau, raws li cov khoom siv kho kom zoo nkauj zoo nkauj, xiav marble slab muaj qhov tseem ceeb ntawm kev lag luam thiab kev loj hlob muaj peev xwm, txawm nyob rau hauv daim ntawv ntuj los yog khoom tsim. Los ntawm kev nruam kev thev naus laus zis thiab kev txhim kho cov txheej txheem, kev ua haujlwm thiab daim ntawv thov ntawm xiav marble slabs tuaj yeem txhim kho ntxiv kom tau raws li kev lag luam xav tau rau cov khoom zoo nkauj zoo nkauj.
