Uhlalutyo lokuqina kunye nozinzo lwesiseko segranite.

 

I-Granite, ilitye lendalo elisetyenziswa kakhulu, liyaziwa ngokuqina kwayo nokuzinza kwayo, nto leyo eyenza ukuba ibe lolona khetho lufanelekileyo kwiindlela ezahlukeneyo zokwakha. Uhlalutyo lokuqina kunye nokuzinza kweziseko ze-granite lubalulekile ekuqondeni ukusebenza kwazo phantsi kweemeko ezahlukeneyo zokusingqongileyo kunye nemithwalo.

I-Granite lilitye eliyi-igneous elenziwe ngokuyintloko yi-quartz, i-feldspar, kunye ne-mica, enegalelo kumandla ayo angaqhelekanga kunye nokumelana nemozulu. Xa kuhlalutywa ukuqina kweziseko ze-granite, kukho izinto ezininzi ezibandakanyekayo, kubandakanya ukwakheka kwezimbiwa, ukubola, kunye nokubakho kweemfanta okanye ukwaphuka. Ezi mpawu zimisela ukuba i-granite inokumelana kakuhle kangakanani neenkqubo zemozulu zomzimba nezekhemikhali, ezifana nemijikelo yokukhenkceza, imvula ene-asidi, kunye nokukrala.

Uhlalutyo lozinzo lugxile kubuchule begranite bokugcina ulungelelwaniso lwayo phantsi kwemithwalo eyahlukeneyo, kuquka amandla angashukumiyo natshintshayo. Oku kubaluleke kakhulu kwizicelo ezifana nokwakhiwa kwendlela, apho iziseko zegranite zisebenza njengeengqimba ezisisiseko. Iinjineli zihlala zenza uvavanyo lokuvavanya amandla okuxinzelela, amandla okucheba, kunye nemodulus yokuqina kwegranite, ukuqinisekisa ukuba inokuxhasa ubunzima bezithuthi kwaye imelane nokuguquguquka ngokuhamba kwexesha.

Ngaphezu koko, impembelelo yokusingqongileyo kwiziseko zegranite kufuneka iqwalaselwe. Izinto ezinje ngokuguquguquka kobushushu, amanqanaba okufuma, kunye nokuvezwa kwiikhemikhali zinokuchaphazela ukusebenza kwexesha elide kwegranite. Ukugcinwa nokubekwa esweni rhoqo kunokunceda ekunciphiseni iingxaki ezinokubakho, ukuqinisekisa ukuba iziseko zegranite zihlala zizinzile kwaye zihlala ixesha elide ubomi bazo bonke.

Ukuqukumbela, uhlalutyo lokuqina nozinzo lweziseko zegranite lubalulekile ukuqinisekisa ukusebenza kwazo kakuhle kwiiprojekthi zokwakha. Ngokuqonda iimpawu zegranite kunye nezinto ezichaphazela ukusebenza kwayo, iinjineli zinokwenza izigqibo ezinolwazi eziphucula ixesha elide kunye nokuthembeka kwezakhiwo ezakhiwe kwiziseko zegranite.
