Iqonga legranite liqonga elenziwe ngegranite. Lenziwe ngelitye elitshisiweyo, igranite lilitye eliqinileyo nelikristale. Ekuqaleni lenziwe ngefeldspar, iquartz, kunye negranite, lixutywe neminerali enye okanye ezingaphezulu ezimnyama, zonke zicwangciswe ngendlela efanayo.
I-granite yenziwe kakhulu yi-quartz, i-feldspar, kunye ne-mica. I-Feldspar ibandakanya i-40%-60%, kwaye i-quartz ingama-20%-40%. Umbala wayo uxhomekeke kuhlobo kunye nobungakanani bezi zinto. I-granite lilitye elicwebezelayo ngokupheleleyo. I-granite esemgangathweni ophezulu ineenkozo ezintle nezifanayo, isakhiwo esixineneyo, umxholo ophezulu we-quartz, kunye nokukhanya okukhanyayo kwe-feldspar.
I-Granite inomxholo ophezulu we-silica, nto leyo eyenza ibe lilitye eline-asidi. Amanye ama-granite aqulathe ubuninzi bezinto ezine-radioactive, ngoko ke olu hlobo lwe-granite kufuneka luthintelwe ukusetyenziswa ngaphakathi. I-Granite inesakhiwo esixineneyo, iqinile, kwaye iyamelana nee-acids, i-alkalis, kunye ne-weathering, nto leyo eyenza ukuba ifaneleke ukusetyenziswa ngaphandle ixesha elide. I-Granite ineempawu ezilandelayo:
1. I-Granite inesakhiwo esixineneyo, inamandla aphezulu okucinezelwa, ayifunxwa ngamanzi amaninzi, ilukhuni kakhulu kumphezulu, izinzile kakuhle kwiikhemikhali, kwaye ihlala ixesha elide, kodwa ayixhathisi kakuhle emlilweni.
2. I-granite inesakhiwo esincinci esineenkozo ezincinci, eziphakathi, okanye ezirhabaxa, okanye isakhiwo se-porphyritic. Iinkozo zayo ziyafana kwaye zincinci, zinezikhewu ezincinci (i-porosity ngokubanzi iphakathi kwe-0.3% ukuya kwi-0.7%), ukufunxwa kwamanzi okuncinci (ngokuqhelekileyo iphakathi kwe-0.15% ukuya kwi-0.46%), kunye nokumelana kakuhle neqabaka.
3. I-granite iqinile, inobunzima be-Mohs obumalunga ne-6 kunye nobunzima obuqala kwi-2.63 g/cm³ ukuya kwi-2.75 Uluhlu lwe-g/(cm³) lunamandla okucinezela angama-100-300 MPa, kunye ne-granite ecolekileyo efikelela kwi-300 MPa. Amandla ayo okugoba ngokubanzi aphakathi kwe-10 kunye ne-30 MPa.
Okwesine, igranite inezinga eliphezulu lemveliso, iyakwazi ukusetyenziswa kwiindlela ezahlukeneyo zokucubungula, kwaye ineempawu ezintle zokudibanisa i-slab. Ngaphezu koko, igranite ayigugi lula, nto leyo eyenza ifaneleke kwiinjongo zokuhombisa zangaphandle.
Ukugcina iqonga lemabula (i-marble slab) kufuna ukumisela ukunyamezela kunye neemfuno zokugcinwa kweqonga lemabula langoku, kunye nokumisela ukuba umphezulu womsebenzi unemigodi na. Ukuba iqonga lemabula linemigodi emincinci kumphezulu walo, kufuneka libuyiselwe kumzi-mveliso ukuze licutshungulwe. Ukuba ukuchaneka kutshintshile kuphela, ukulungiswa kufuneka kwenziwe kwindawo esetyenziswa kuyo. Emva kokusetyenziswa ixesha elide, rhoqo, iqonga lemabula liya kuba Ukuba iqonga lemabula lithe tyaba kakhulu, impazamo yokuchaneka iya kwanda kancinci kancinci, nto leyo ekhokelela ekuchanekeni okungachanekanga. Kule meko, ifuna ukulungiswa.
Amanyathelo okulungisa amaqonga emarble:
1. Jonga ukuchaneka kweqonga lemabula uze ubone impazamo yalo yangoku.
2. Sila iqonga lemabula kakuhle usebenzisa izixhobo zokusila kunye nezixhobo zokusila ukuze ufumane umgangatho ofunekayo.
3. Ukugaya kwesibini okuncinci kweqonga lemabula emva kokugaya okurhabaxa kukususa imikrwelo enzulu nokufikelela kwinqanaba elifunekayo.
4. Gaya umphezulu wokusebenza weqonga lemabula ukuze ufumane ukuchaneka okufunekayo.
5. Vavanya ukuchaneka kweqonga lemabula emva kokupolishwa, kwaye kwakhona emva kwexesha elithile.
