Ukuqina nokuhlaziywa kokuqina kwesisekelo se-granite.

 

I-Granite, itshe lemvelo elisetshenziswa kabanzi, idume ngokuqina kwayo nokuqina kwayo, okwenza kube ukukhetha okuhle kwezicelo ezahlukene zokwakha. Ukuhlaziywa kokuqina nokuqina kwezisekelo ze-granite kubalulekile ekuqondeni ukusebenza kwazo ngaphansi kwezimo ezahlukene zemvelo kanye nemithwalo.

I-Granite iyidwala eliyi-igneous elakhiwe ngokuyinhloko yi-quartz, i-feldspar, ne-mica, elifaka isandla emandleni alo angavamile kanye nokumelana nokuguquguquka kwesimo sezulu. Lapho kuhlaziywa ukuqina kwezisekelo ze-granite, kunezici eziningana ezibandakanyekayo, okuhlanganisa ukwakheka kwamaminerali, ukuvuleka kwenhlabathi, kanye nokuba khona kwemifantu noma ukuqhekeka. Lezi zici zinquma ukuthi i-granite ingakwazi kanjani ukumelana nezinqubo zokuguquguquka kwesimo sezulu ngokomzimba nangokwekhemikhali, njengemijikelezo yokuqandisa nokuncibilika, imvula ene-asidi, kanye nokuguguleka.

Ukuhlaziywa kokuqina kugxila ekhonweni le-granite lokugcina ubuqotho besakhiwo sayo ngaphansi kwemithwalo eyahlukahlukene, kufaka phakathi amandla angaguquki naguquguqukayo. Lokhu kubaluleke kakhulu ekusetshenzisweni okufana nokwakhiwa komgwaqo, lapho izisekelo ze-granite zisebenza njengezingqimba eziyisisekelo. Onjiniyela bavame ukwenza izivivinyo zokuhlola amandla okucindezela, amandla okusika, kanye ne-modulus yokuqina kwe-granite, ukuqinisekisa ukuthi ingasekela isisindo sezimoto futhi imelane nokuguquguquka ngokuhamba kwesikhathi.

Ngaphezu kwalokho, umthelela wemvelo ezisekelweni ze-granite kumele ucatshangelwe. Izici ezifana nokushintshashintsha kwezinga lokushisa, amazinga omswakama, kanye nokuchayeka kumakhemikhali kungathinta ukusebenza kwesikhathi eside kwe-granite. Ukugcinwa nokuqapha njalo kungasiza ekunciphiseni izinkinga ezingaba khona, kuqinisekiswe ukuthi izisekelo ze-granite zihlala zizinzile futhi ziqinile phakathi nesikhathi sazo sokuphila.

Ekuphetheni, ukuhlaziywa kokuqina nokuqina kwezisekelo ze-granite kubalulekile ukuqinisekisa ukusebenza kwazo kahle kumaphrojekthi okwakha. Ngokuqonda izakhiwo ze-granite kanye nezici ezithonya ukusebenza kwayo, onjiniyela bangenza izinqumo ezinolwazi ezithuthukisa ubude besikhathi kanye nokuthembeka kwezakhiwo ezakhiwe ezisekelweni ze-granite.
