Urubuga rwa granite ni urubuga rukozwe muri granite. Rwakozwe mu ibuye ry’umukara, granite ni ibuye rikomeye kandi rimeze nk’ibuye rya kristu. Mbere na mbere ryari rigizwe na feldspar, quartz, na granite, rivanze n’amabuye y’umukara amwe cyangwa menshi, yose atunganyijwe mu buryo bumwe.
Granite igizwe ahanini na quartz, feldspar, na mica. Feldspar igizwe na 40%-60%, naho quartz igizwe na 20%-40%. Ibara ryayo riterwa n'ubwoko n'ingano y'ibi bice. Granite ni ibuye ryuzuye kristu. Granite nziza cyane ifite ibinyampeke byiza kandi bisa, imiterere y'urubura, quartz nyinshi, n'urumuri rwa feldspar rugaragara.
Granite ifite silika nyinshi, bigatuma iba ibuye rigizwe n'aside. Amwe mu ma granite arimo ibintu bike bya radiation, bityo ubwo bwoko bwa granite bugomba kwirindwa gukoreshwa mu nzu. Granite ifite imiterere ikomeye, imiterere ikomeye, kandi irwanya aside, alkali, ndetse n'ikirere kibi, bigatuma ikoreshwa hanze igihe kirekire. Granite ifite ibi bikurikira:
1. Granite ifite imiterere ikomeye, ikomeye cyane, amazi make, ubukana bwinshi bw'ubuso, ihamye neza mu by'ubutabire, kandi iramba cyane, ariko idashobora kurwanya umuriro.
2. Granite ifite imiterere y'ibice bito, biciriritse cyangwa binini, cyangwa imiterere ya porphyritic. Ibice byayo ni bimwe kandi bito, bifite icyuho gito (ubusanzwe ni 0.3% kugeza 0.7%), amazi make anyuramo (ubusanzwe ni 0.15% kugeza 0.46%), kandi irwanya ubukonje neza.
3. Granite ni ikomeye, ifite ubukana bwa Mohs bwa hafi 6 n'ubucucike buri hagati ya 2.63 g/cm³ na 2.75. Ingano ya g/(cm³) ifite imbaraga zo gukanda za 100-300 MPa, hamwe na granite yoroheje igera kuri MPa irenga 300. Ubusanzwe imbaraga zayo zo gukanda ziba hagati ya MPa 10 na 30.
Icya kane, granite itanga umusaruro mwinshi, ikoreshwa mu buryo butandukanye bwo kuyitunganya, kandi ifite ubushobozi bwiza bwo kuyihuza n'amasafuriya. Byongeye kandi, granite ntiyoroshye kuyirwanya, bigatuma ikoreshwa mu mirimo yo gushushanya hanze.
Kubungabunga urubuga rwa marble (marble slab) bisaba kumenya ubushobozi bwo kwihanganira no kubungabunga urubuga rwa marble ruriho ubu, ndetse no kumenya niba ubuso bw'aho bakorera burimo imyobo. Niba urubuga rwa marble rufite imyobo mito ku buso bwarwo, rugomba gusubizwa mu ruganda kugira ngo rutunganywe. Niba ubwiza bwarahindutse gusa, gusana bigomba gukorwa aho bikorerwa. Nyuma yo gukoreshwa igihe kirekire kandi kenshi, urubuga rwa marble ruzaba Iyo urubuga rwa marble rudakomeye cyane, ikosa ry'ubwiza rizagenda ryiyongera buhoro buhoro, bigatuma ubwiza budakwiye. Muri iki gihe, bisaba gusanwa.
Intambwe zo kubungabunga ibyuma bya marble:
1. Reba neza urwego rw'amabuye y'agaciro hanyuma umenye ikosa ririho ubu.
2. Siga neza urubuga rwa marble ukoresheje ibikoresho byo gusya n'ibikoresho byo gusya kugira ngo ugere ku rwego rukenewe.
3. Uburyo bwa kabiri bwo gusya urukuta rwa marble nyuma yo gusya neza ni ugukuraho iminkanyari miremire no kugera ku burebure bukenewe.
4. Gusya ubuso bw'aho urubuga rwa marble rukorera kugira ngo ugere ku buhanga bukenewe.
5. Gerageza uburyo urubuga rwa marble rukora neza nyuma yo kurusukura, hanyuma wongere ugerageze nyuma y'igihe runaka.
