Izingxenye ze-granite mechanical zisetshenziswa kabanzi emikhiqizweni yedivayisi yokucubungula ngokunembile ngenxa yezakhiwo zazo ezinhle kakhulu njengokuqina okuphezulu, ukunwetshwa okuphansi kokushisa, kanye nomthamo omuhle kakhulu wokudambisa. Kodwa-ke, njengazo zonke ezinye izinto, aziphelele futhi zingase zibe namaphutha athile okudingeka acatshangelwe ekusetshenzisweni ngokunembile.
Enye yeziphambeko ezivame ukubonwa ezingxenyeni ze-granite ukuvela kokuqhekeka noma imifantu ebusweni. Lezi ziphambeko zingabangelwa yizici eziningana ezifana nokulayisha ngokweqile, ukufakwa okungafanele, ukucindezeleka kokushisa, noma ukuchayeka endaweni ezungezile enzima. Ukuvimbela lokhu, izingxenye kufanele zakhiwe nge-geometry efanele kanye nobukhulu bodonga, futhi kufanele kuthathwe izinyathelo ezanele zokuvimbela ukulayisha ngokweqile noma ukucindezeleka kokushisa.
Esinye isici esingaba khona ezingxenyeni ze-granite ukwakheka kwama-pores kanye nama-voids ebusweni noma ngaphakathi kwento ngokwayo. La maphutha angenza buthaka isakhiwo futhi aphazamise ukunemba komkhiqizo wokugcina. Ukukhetha ngokucophelela nokuhlola izinto zokusetshenziswa, kanye nezinqubo ezifanele zokulungisa kungavimbela ukwakheka kwama-pores kanye nama-voids ezingxenyeni ze-granite.
Ngaphezu kwalokho, izingxenye ze-granite zingase zibonise ukwehluka kokusicaba kobuso noma ukuthambekela kobuso obuhlobene. Lokhu kwehluka kungavela ekuhlukeni kwemvelo kwezinto, kanye nasenqubweni yokukhiqiza. Ukuqinisekisa ukunemba komkhiqizo wokugcina, lokhu kwehluka kufanele kulinganiswe ngokucophelela futhi kunxeshezelwe ngesikhathi senqubo yokugaya.
Esinye isici esingaba khona ezingxenyeni ze-granite ukuhlukahluka kwama-coefficients okwandisa ukushisa kuyo yonke into. Lokhu kungabangela ukungazinzi kobukhulu kanye nokunemba okuncishisiwe ebangeni lokushisa. Ukuze kuncishiswe lo mphumela, onjiniyela bangaklama izingxenye ukuze banciphise ukuphambuka kokushisa, noma abakhiqizi bangase basebenzise ukwelashwa kokushisa ukuze bafinyelele i-coefficient yokwandisa ukushisa efanayo kuyo yonke into.
Sekukonke, izingxenye ze-granite ziyizinto ezinhle kakhulu zokucubungula imikhiqizo yedivayisi ngokunembile, kodwa zingase zibe neziphambeko ezingaba khona ezidinga ukucatshangelwa nokuphathwa ngokucophelela. Ngokuqonda lezi ziphambeko nokuthatha izinyathelo ezifanele zokuzivimbela noma ukuzinciphisa, abakhiqizi bangakhiqiza izingxenye zekhwalithi ephezulu ezihlangabezana nezidingo zokunemba okuphezulu zezimboni zanamuhla.
