Mu rwego rw'ibikoresho byo gupima neza, ubwiza n'ubudahangarwa bw'ibikoresho bifitanye isano itaziguye n'ubunyangamugayo bw'ibipimo, kandi guhitamo ibikoresho byo gutwara no gushyigikira igikoresho cyo gupima ni ingenzi cyane. Granite na marble, nk'ibikoresho bibiri bisanzwe by'amabuye meza, bikunze kwitabwaho mu kubaka ibikoresho byo gupima neza, ariko ni ikihe cyiza kurusha ibindi? Reka ducukumbure cyane.
Kugereranya ubuhamye
Gutuza ni inkingi y'ingenzi mu gupima neza ibikoresho. Granite ikorwa mu butaka bw'Isi, nyuma y'ubushyuhe bwinshi n'umuvuduko mwinshi igihe kirekire irazima, imiterere y'imbere iba ikomeye kandi isa. Imyaka miliyoni y'ubusaza karemano ituma imbaraga zayo imbere zirekurwa neza, ibyo bigatuma granite ihora ihagaze neza cyane. Iyo ibintu bifitanye isano n'ibidukikije nk'ubushyuhe n'ubushuhe bihindutse, ihinduka ry'ibara rya granite riba rito cyane.
Mu buryo bunyuranye, marble, nubwo ikorwa nyuma y’igihe kirekire cya geologiya, ariko imiterere yayo ya kristu ni nk'iy'ubururu, kandi ibigizemo ibintu birimo imyunyu ngugu myinshi nka karubone karubone. Ibi bintu bituma marble yaguka cyangwa igacika byoroshye mu gihe habayeho impinduka mu bidukikije. Urugero, mu bidukikije bifite ihindagurika rikomeye ry'ubushyuhe, impinduka mu bunini bwa marble zishobora kubangamira uburyo bwo gupima ibikoresho bipima neza, mu gihe granite ishobora gukomeza gutuza no gutanga urufatiro rwizewe rw'ibikoresho bipima.
Ubukomere n'ubudahangarwa bw'ingufu
Ibikoresho byo gupima neza mu gihe kirekire, nta kabuza bizahura n'ibibazo bitandukanye byo gushwanyagurika no kugongana. Granite irakomeye mu miterere yayo, kandi ubukana bwa Mohs bwayo busanzwe buri hagati ya 6-7, bushobora kurwanya kwangirika no gushwanyagurika inyuma. Mu gihe cyo gushyira ibikoresho n'ingero byayo kenshi no kubijyana, ubuso bwa granite ntibushobora gusiga ibimenyetso bigaragara, kugira ngo bugumane ubugari n'ubuziranenge igihe kirekire.
Ubukomere bwa marble buri hasi, kandi ubukomere bwa Mohs muri rusange ni 3-5. Ibi bivuze ko mu gihe kimwe cyo gukoreshwa, ubuso bwa marble bukunze gushwaragurika no kwangirika, kandi iyo ubuso bumeze neza, bizagira ingaruka mbi ku buryo ibikoresho bipima neza bikoreshwa. Ku bikoresho bipima bisaba imikorere y’igihe kirekire kandi ihamye, ubukomere bwinshi n’ubudahangarwa bw’amabuye y’agaciro bya granite nta gushidikanya ko ari amahitamo meza kurushaho.
Isesengura ry'ubudahangarwa bw'inkongi
Ibinyabutabire bitandukanye bishobora kuboneka mu bipimo, nko guhinduka kw'ibinyabutabire bikomoka kuri aside, ibyo bikaba imbogamizi ku burwanyi bw'ibikoresho by'ibikoresho. Granite igizwe ahanini na quartz, feldspar n'indi myunyu ngugu, imiterere ya shimi irahamye, ifite ubudahangarwa bwiza bwa aside, ubudahangarwa bwa alkali. Mu bidukikije bigoye bya shimi, granite ishobora kugumana imiterere yayo bwite n'iya shimi igihe kirekire kugira ngo ikore neza ibikoresho bipima neza.
Bitewe n'imikorere y'ibinyabutabire by'igice cyayo cy'ingenzi cya kalisiyumu karubone, marble ikunze kugira ingaruka mbi ku binyabutabire iyo ihuye n'ibintu birimo aside, bigatera kwangirika no kwangirika k'ubuso. Iyi ngeso ntizagira ingaruka gusa ku isura ya marble, ahubwo inangiza imiterere yayo, hanyuma ikagira ingaruka ku buryo bunoze bw'ibikoresho bipima neza. Kubwibyo, mu bipimo aho hari ibyago byo kwangirika kw'ibinyabutabire, kurwanya kwangirika kw'granite bituma iba ibikoresho byizewe kurushaho.
Ifite ubushobozi bwo guhagarara neza, gukomera no kwangirika ndetse no kurwanya ingese n'ibindi bintu, granite mu bimenyetso by'ingenzi bitandukanye yagaragaje ubushobozi bwiza kurusha marble. Ku bikoresho bipima neza bisaba ubuhanga kandi bihamye, granite nta gushidikanya ko ari amahitamo meza kurushaho. Ishobora gutanga ishingiro rihamye kandi ryizewe ry'ibikoresho bipima, kwemeza ko ibisubizo bipima ari ukuri kandi byizerwa, no gufasha gupima neza mu bushakashatsi bwa siyansi, umusaruro w'inganda n'izindi nzego gukora neza.
