Nyob rau hauv cov txheej txheem, cov ntaub ntawv raw cov ntaub ntawv rau zus tau tej cov unburned bricks ua los ntawm unburned cib tshuab yog nplua nuj. Tam sim no, kev tsim cov khib nyiab ntau ntxiv muab qhov kev lees paub zoo rau kev muab cov khoom siv raw rau cov cib tsis tau tawg, thiab cov txheej txheem thiab thev naus laus zis yog nyob rau theem ua hauv Suav teb. Peb txhua tus paub tias cov khoom ua tau zoo nyob ntawm tus yam ntxwv ntawm cov khoom siv raw thiab cov tshuab tsim. Raws li kev soj ntsuam ntawm lub teb chaws phab ntsa thiab ru tsev cov ntaub ntawv zoo soj ntsuam qhov chaw, cov txheej txheem kev ua tau zoo ntawm lub cib ua los ntawm cov uas tsis yog raug rho tawm haujlwm cib tshuab yog siab tshaj li ntawm cov tsoos av nplaum liab cib, lub peev xwm thiab dej nqus tau zoo dua li cov pob zeb cib zoo tib yam, thiab qhuav shrinkage thiab thermal conductivity yog me dua li cov khoom siv pob zeb zoo tib yam. Nyob rau hauv luv luv, ntau yam kev xeem cov ntaub ntawv qhia tau hais tias lub compressive structural kev ua tau zoo ntawm unburned cib yog zoo dua li cov tsoos liab cib. Nws tuaj yeem tiv taus qhov kev sim ntawm keeb kwm thiab lub sijhawm.
