Iislabhu zegranite zifunyanwa kwiileya zemarble ezingaphantsi komhlaba. Emva kwezigidi zeminyaka yokwaluphala, imilo yazo ihlala izinzile ngokumangalisayo, isusa umngcipheko wokuguquka ngenxa yokuguquguquka kobushushu okuqhelekileyo. Le nto yegranite, ekhethwe ngononophelo kwaye ivavanywa ngokuqatha ngokomzimba, ineekristale ezintle kunye nokwakheka okuqinileyo, inamandla okucinezelwa angama-2290-3750 kg/cm² kunye nobunzima obuyi-6-7 kwisikali seMohs.
1. Ngokuyintloko zigxile ekuchanekeni okuzinzileyo kunye nokulula kokugcinwa, ii-granite slabs zinesakhiwo esincinci esincinci, umphezulu ogudileyo, ongenakugugiswa, kunye noburhabaxa obuphantsi.
2. Emva kokwaluphala kwendalo ixesha elide, ii-granite slabs zisusa uxinzelelo lwangaphakathi, nto leyo ebangela ukuba izinto ezizinzileyo nezingenakuguquguquka.
3. Azinazo ii-asidi, ii-alkali, ukugqwala, kunye nemagnetism; ziyamelana nokufuma kunye nokugqwala, okwenza kube lula ukuzisebenzisa nokuzigcina zisemgangathweni. Zikwanayo ne-linear expansion coefficient ephantsi kwaye azichaphazeleki kakhulu bubushushu.
4. Iimpembelelo okanye imikrwelo kumphezulu wokusebenza zenza imingxunya kuphela, engenamiqolo okanye imigqomo, engenampembelelo ekuchanekeni kokulinganisa.
5. Iislabhu zegranite zenziwe ngeemaleko zemarble ezingaphantsi komhlaba. Emva kwezigidi zeminyaka yokwaluphala, imilo yazo ihlala izinzile kakhulu, isusa umngcipheko wokuguquka ngenxa yokuguquguquka kobushushu. Igranite, ekhethwe ngononophelo kwaye ivavanywe ngokungqongqo, ineekristale ezintle kunye nobume obuqinileyo. Amandla ayo okucinezela afikelela kwi-2290-3750 kg/cm², kwaye ubunzima bayo bufikelela kwi-6-7 kwisikali seMohs.
