Muaj cov khoom lag luam nplua nuj ntawm cov khoom siv raw rau kev tsim cov pob zeb uas tsis tau tawg ua los ntawm lub tshuab cib tsis tau tawg. Tam sim no, kev tsim cov khib nyiab ntau ntxiv muab cov khoom lag luam txhim khu kev qha rau cov cib tsis tau tawg, thiab cov thev naus laus zis thiab cov txheej txheem yog nyob rau theem ua hauv Suav teb. Raws li peb txhua tus paub, cov khoom ua tau zoo nyob ntawm cov yam ntxwv ntawm cov khoom siv raw thiab cov tshuab tsim. Raws li kev soj ntsuam ntawm lub teb chaws qhov chaw soj ntsuam zoo rau phab ntsa thiab lub ru tsev cov ntaub ntawv, lub cib qauv kev ua tau zoo tsim 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 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 sim 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, thiab nws muaj peev xwm tiv taus qhov kev xeem ntawm keeb kwm thiab lub sij hawm.
