Mu gukora ibice by'ubuhanga, imbonerahamwe y'ubuhanga ifite umurongo munini iba imeze nk'iy'icyuma gishyushya, gitanga uburyo bwo gushyira ibintu neza kandi nta makosa buri gihe. Kandi "intwaro y'ibanga" yayo ni ishingiro rya granite rinini! Kuki iri buye rishobora kunoza cyane uburyo bwo kongera gushyira ibintu neza mu mwanya waryo? Reka tubivumbure hamwe!
Mbere na mbere, granite ifite ubucucike bwinshi "irwanya ubwubatsi mu buryo busanzwe". Ifite ubucucike bwinshi n'imiterere mito. Ingufu zayo zo gukandagira zirakomeye kurusha iz'icyuma gisanzwe. Iyo ameza yo gukoreraho ikunze kwimurwa no guhindurirwa, ntabwo ihinduka cyangwa ngo ihinduke. Byongeye kandi, igipimo cyayo cyo kwaguka k'ubushyuhe kiba kiri hasi cyane. Nubwo ubushyuhe bw'ikirere bwahinduka, ntabwo izatera impinduka nk'uko ibyuma bihinduka bitewe no "kwaguka no guhindagurika k'ubushyuhe". Urugero, ibikoresho bisanzwe bishobora guhinduka cyane bitewe n'itandukaniro ry'ubushyuhe bwa 1℃, mu gihe ihinduka rya granite ifite ubucucike bwinshi riba rito cyane, rituma habaho ahantu hahamye kandi hizewe buri gihe.
Icya kabiri, ni "umuhanga mu gufata impanuka". Imbonerahamwe y'akazi ifite imiterere myinshi izatera umujinya mu gihe cyo gukora, ibyo bizagira ingaruka ku buryo ishyirwa mu mwanya wayo neza. Granite ifite ubucucike bwinshi mu buryo busanzwe ifite imiterere yo "gufata amajwi no kugabanya urusaku", ishobora gufata hejuru ya 90% by'imirasire ifite imiterere myinshi. Ni nko kwambara "icyuma gikingira impanuka" ku ntebe y'akazi, bigatuma ikomeza kuba ihamye nk'umusozi nubwo ikora ku muvuduko mwinshi. Byongeye kandi, nyuma yo kuvurwa byihariye, "ubushyuhe" bwayo bw'imbere bwaratunganyijwe kugira ngo bukomeze kuba bwiza. Ndetse no nyuma yo gukoreshwa igihe kirekire, ntabwo izahinduka gato, birushaho kwemeza ko ari iy'ukuri.
Amaherezo, mu bijyanye n'igishushanyo mbonera, injeniyeri nazo zabitekerejeho cyane. Mu kunoza imiterere y'ibanze, ishyushya neza, kandi imiterere y'ingingo zishyigikira nayo irahindurwa kugira ngo igabanye ingaruka mbi mu gihe cyo kugenda kwa buri ruhande. Nyuma y'uko ikigo runaka gikoresheje ishingiro rya granite rinini, uburyo bwo gusubiramo imiterere y'imbonerahamwe y'imirimo y'imirongo myinshi bwiyongereyeho ibirenze 60%, kandi ibice byakozwe byari bifite ubwiza n'ubuziranenge!
Urashaka intebe yo gukoreraho ifite imiterere myinshi ishobora kwerekezwa aho iri? Guhitamo ishingiro rya granite rifite ubucucike bwinshi ni amahitamo meza rwose!
