Uhlalutyo lokuzinza kunye nokuzinza kwesiseko segranite.

 

I-Granite, ilitye lendalo elisetyenziswa ngokubanzi, liyaziwa ngokuhlala kunye nokuzinza, okwenza kube yinto efanelekileyo yokukhetha izicelo ezahlukeneyo zokwakha. Uhlalutyo lokuzinza kunye nozinzo lweziseko zegranite lubalulekile ekuqondeni ukusebenza kwazo phantsi kweemeko ezahlukeneyo zokusingqongileyo kunye nemithwalo.

I-Granite lilitye elivuthayo elihlanganiswe ikakhulu yi-quartz, i-feldspar, kunye ne-mica, enegalelo kumandla ayo akhethekileyo kunye nokuchasana nemozulu. Xa uhlalutya ukuqina kweziseko zegranite, kukho izinto ezininzi eziza kudlala, kubandakanywa ukubunjwa kwamaminerali, i-porosity, kunye nobukho be-fissures okanye i-fractures. Ezi mpawu zimisela indlela igranite enokumelana ngayo neenkqubo zemozulu kunye neekhemikhali, ezinjengomjikelo wokunyibilika komkhenkce, imvula eneasidi, kunye nokugqabhuka.

Uhlalutyo lozinzo lujolise kubuchule begranite bokugcina ingqibelelo yesakhiwo phantsi kwemithwalo eyahlukeneyo, kubandakanywa amandla amileyo kunye aguqukayo. Oku kubaluleke kakhulu kwizicelo ezifana nokwakhiwa kweendlela, apho iziseko zegranite zisebenza njengeziseko ezisisiseko. Iinjineli zihlala ziqhuba iimvavanyo zokuvavanya amandla acinezelayo, amandla okucheba, kunye nemodyuli ye-elasticity yegranite, iqinisekisa ukuba inokuxhasa ubunzima bezithuthi kwaye ixhathise inguquko ekuhambeni kwexesha.

Ngaphezu koko, impembelelo yokusingqongileyo kwiziseko zegranite kufuneka ziqwalaselwe. Izinto ezifana nokuguquguquka kobushushu, amanqanaba okufuma, kunye nokuvezwa kweekhemikhali kunokuchaphazela ukusebenza kwexesha elide legranite. Ukugcinwa rhoqo kunye nokubeka iliso kunokunceda ukunciphisa imiba enokubakho, ukuqinisekisa ukuba iziseko zegranite zihlala zizinzile kwaye zomelele kubo bonke ubomi bazo.

Ukuqukumbela, ukuhlalutya ukuqina kunye nozinzo lweziseko zegranite zibalulekile ekuqinisekiseni ukusebenza kwazo kwiiprojekthi zokwakha. Ngokuqonda iipropathi zegranite kunye nezinto eziphembelela ukusebenza kwayo, iinjineli zinokwenza izigqibo ezinolwazi ezandisa ixesha elide kunye nokuthembeka kwezakhiwo ezakhiwe kwiziseko zegranite.
