Ni irihe tandukaniro rikomeye riri hagati y’ibice bya granite by’ubuziranenge n’ibice bya marble by’ubuziranenge? Iri tandukaniro rigira izihe ngaruka ku ikoreshwa ryabyo mu gupima no gutunganya neza?

Granite na marble byombi ni amahitamo azwi cyane ku bice by’ingenzi mu nganda zitandukanye, cyane cyane mu gupima no gutunganya neza. Ariko, hari itandukaniro rikomeye mu buryo buhamye bwabyo rishobora kugira ingaruka zikomeye ku ikoreshwa ryabyo muri ubu buryo.

Granite ni amahitamo asanzwe ku bice by’ingenzi bitewe n’uko ihamye cyane. Ni ibuye rikomeye kandi rikomeye rikomoka ku gushonga buhoro buhoro kwa magma munsi y’isi. Ubu buryo bwo gukonjesha buhoro buhoro butuma habaho imiterere imwe, ifite imiterere myiza ituma granite ikomera kandi ihamye. Mu buryo bunyuranye, marble ni ibuye ryahindutse rikomoka ku gushonga kwa limestone mu gihe cy’umuvuduko mwinshi n’ubushyuhe bwinshi. Nubwo marble nayo ari ikintu kiramba kandi gishimishije, nta buhamye n’imbaraga bya granite.

Kimwe mu bitandukanya bikomeye hagati y’ibice bya granite ikora neza n’ibice bya marble ikora neza ni ubudahangarwa bwabyo mu kwaguka kw’ubushyuhe. Granite ifite ingano nto cyane y’ubushyuhe, bivuze ko irwanya cyane impinduka mu bushyuhe. Ibi bituma iba ibikoresho byiza ku bice bya granite ikora neza bisaba ubudahangarwa mu bushyuhe bwinshi. Ku rundi ruhande, marble ifite ingano yo kwaguka kw’ubushyuhe bwinshi, bigatuma irushaho guhura n’impinduka mu bushyuhe hamwe n’ihindagurika ry’ubushyuhe. Ibi bishobora kuba ikintu cy’ingenzi mu gupima no gutunganya neza, aho n’impinduka ntoya mu bushyuhe zishobora gutera amakosa n’amakosa.

Irindi tandukaniro rikomeye ni uko zidashobora kwangirika no gushwanyagurika. Granite irakomeye cyane mu kwangirika no gushwanyagurika, bigatuma ikoreshwa mu buryo bunoze kandi buhora buhura n’ibintu bihindagurika. Ubukana bwayo no kuramba kwayo bituma igumana ubuziranenge bwayo uko igihe kigenda gihita, ndetse no mu gihe ikoreshwa cyane. Marble, nubwo ikiri ibikoresho biramba, ntabwo irwanya kwangirika no gushwanyagurika nk’uko granite ibikora. Ibi bishobora kuba ikibazo mu mikoreshereze y’ibikoresho binoze aho ibice bihora bihura n’ibindi bikoresho, kuko ubushobozi bwo kwangirika no guhindagurika buba bwinshi mu bice binoze.

Mu gupima no gutunganya neza, itandukaniro mu guhagarara neza hagati y’ibice bya granite na marble rishobora kugira ingaruka zikomeye ku buryo buboneye n’ubwizerwe bw’ibikorwa. Ibikoresho byo gupima neza, nk’imashini zipima neza n’ibice byo hejuru, bishingiye ku guhagarara neza no ku buryo bugororotse bw’ibice kugira ngo bipime neza kandi bisubirwemo. Guhagarara neza kw’ibice bya granite bituma iba amahitamo meza kuri izi porogaramu, kuko itanga urufatiro ruhamye kandi rwizewe rwo gupima neza. Ku rundi ruhande, guhagarara neza kw’ibice bya marble bishobora gutuma habaho amakosa no kutumvikana mu bipimo, bigatera ingaruka mbi ku ireme ry’ibisubizo.

Mu buryo nk'ubwo, mu gutunganya neza, guhagarara neza kw'ibice ni ingenzi cyane kugira ngo habeho kwihanganira gukomeye no kurangiza neza. Granite ikunze gukoreshwa mu gushushanya, ibikoresho, n'ibikoresho mu mikorere y'imashini bitewe n'uko ihamye cyane kandi idahindagurika. Uku guhagarara neza ni ingenzi kugira ngo ikomeze gukora neza no kwemeza ubuziranenge bw'ibicuruzwa byarangiye. Marble, hamwe no guhagarara kwayo ku rugero ruto, ishobora kutabera iyo mikorere kuko ishobora guteza guhindagurika ku buryo butifuzwa n'impinduka mu miterere zigira ingaruka ku buziranenge n'ubwiza bw'ibice byakozwe.

Mu gusoza, itandukaniro rikomeye mu guhagarara neza hagati y’ibice bya granite bitunganye n’ibice bya marble bifite ingaruka zitaziguye ku ikoreshwa ryabyo mu gupima no gutunganya neza. Guhagarara neza kwa granite, kurwanya guhindagurika, no kuramba kwayo bituma iba amahitamo meza ku bice by’ingenzi muri ubu buryo. Ubushobozi bwayo bwo kugumana ubuziranenge n’ubudahinduka mu bushyuhe bwinshi no mu gihe idasaza kandi ishaje bituma iba ibikoresho byiza byo gukoresha ibikoresho by’ubuhanga n’ibice bya mashini. Ku rundi ruhande, nubwo marble ari ibikoresho bireba neza kandi biramba, kudahagarara kwayo no kudasaza no gushwanyagurika bituma idakoreshwa neza aho imiterere n’ubudahinduka ari ingenzi cyane. Gusobanukirwa aya tandukaniro ni ingenzi mu guhitamo ibikoresho bikwiye kugira ngo harebwe ko ari inyangamugayo, byizewe, kandi bifite ireme mu gupima no gutunganya neza.
