Isesengura ry’uburambe n’ubudahangarwa bw’ishingiro rya granite.

 

Granite, ibuye karemano rikoreshwa cyane, rizwiho kuramba no guhamye, bigatuma riba amahitamo meza yo gukoresha mu bwubatsi butandukanye. Isesengura ry’uburambe n’ugukomera kw’inkingi za granite ni ingenzi mu gusobanukirwa imikorere yazo mu bihe bitandukanye by’ibidukikije n’imitwaro itandukanye.

Granite ni ibuye ry’umukara rigizwe ahanini na quartz, feldspar, na mica, rigira uruhare mu gukomera no kurwanya imihindagurikire y’ikirere. Mu gusesengura kuramba kw’inkingi za granite, hari ibintu byinshi bikunze kugaragara, harimo imiterere y’amabuye y’agaciro, imyenge, no kuba hari imiyoboro cyangwa imvune. Ibi biranga granite ibasha kwihanganira imihindagurikire y’ikirere n’imiti, nko gukonja no gushonga, imvura ya aside, no kwangirika.

Isesengura ry’ubudahangarwa ryibanda ku bushobozi bwa granite bwo kugumana ubusugire bwayo mu mitwaro itandukanye, harimo imbaraga zidahinduka n’izihindagurika. Ibi ni ingenzi cyane mu bikorwa nko mu kubaka imihanda, aho ishingiro rya granite rikorera nk'inkingi z'ibanze. Abahanga mu by'imashini bakunze gukora ibizamini kugira ngo basuzume imbaraga zo gukanda, imbaraga zo gukata, n'uburyo granite ihinduka, barebe ko ishobora gushyigikira uburemere bw'ibinyabiziga no kurwanya guhindagurika uko igihe kigenda gihita.

Byongeye kandi, ingaruka ku bidukikije ku rufatiro rwa granite zigomba kwitabwaho. Ibintu nk'ihindagurika ry'ubushyuhe, urugero rw'ubushuhe, no guhura n'ibinyabutabire bishobora kugira ingaruka ku mikorere ya granite mu gihe kirekire. Kuyibungabunga no kuyikurikirana buri gihe bishobora gufasha kugabanya ibibazo bishobora kubaho, bigatuma urwego rwa granite rugumaho kandi rurambye mu gihe cyose rumaze.

Muri make, isesengura ry’ubudahangarwa n’ubudahangarwa bw’ibishingiriro bya granite ni ingenzi kugira ngo bigire akamaro mu mishinga y’ubwubatsi. Mu gusobanukirwa imiterere ya granite n’ibintu bigira ingaruka ku mikorere yayo, abahanga mu by’ubwubatsi bashobora gufata ibyemezo bifatika byongera igihe kirekire n’icyizere cy’inyubako zubatswe ku rufatiro rwa granite.
