Imingcele yezobuchwepheshe yesisekelo se-granite mechanical.

 

I-Granite, idwala elishisayo elisetshenziswa kakhulu, lidume ngokuhlala isikhathi eside namandla, okulenza libe yimpahla efanelekile yezisekelo zemishini kumaphrojekthi ahlukahlukene wokwakha. Ukuqonda amapharamitha wobuchwepheshe ezisekelo zemishini yegwadle kubalulekile konjiniyela nabadwebi bezakhiwo ukuze baqinisekise ubuqotho besakhiwo nempilo ende.

Enye yezinhlaka zobuchwepheshe eziyinhloko ze-granite amandla ayo acindezelayo, ngokuvamile asukela ku-100 kuya ku-300 MPa. Lawa mandla aphezulu acindezelayo avumela i-granite ukuthi imelane nemithwalo ebalulekile, iyenze ifanele imishini esindayo nemishini. Ukwengeza, i-granite ikhombisa i-porosity ephansi, ngokuvamile ephakathi kuka-0.1% kuya ku-0.5%, okunomthelela ekuphikiseni kwayo ukungena emanzini kanye nesimo sezulu samakhemikhali, okwenza ngcono ukufaneleka kwayo ezisekelweni zemishini.

Enye ipharamitha ebalulekile i-modulus of elasticity, okuthi nge-granite icishe ibe ngu-50 kuya ku-70 GPa. Lesi sakhiwo sibonisa ukuthi kungakanani okuzokonakala ngaphansi kwengcindezi, kunikeze imininingwane ekusebenzeni kwayo ngaphansi kwemithwalo eguquguqukayo. I-coefficient ephansi yokwandisa okushisayo kwe-granite, cishe ku-5 kuya ku-7 x 10 ^ -6 / ° C, iqinisekisa ukuthi igcina ubuqotho bayo besakhiwo ngisho nokushintshashintsha kwezinga lokushisa, okwenza kube ukukhetha okuthembekile kwezisekelo ezimweni zezulu ezihlukahlukene.

Ukuminyana kwe-Granite, ngokuvamile phakathi kuka-2.63 kuya ku-2.75 g/cm³, nakho kudlala indima ebalulekile ekwakhiweni kwesisekelo. Ukuminyana okuphezulu kunomthelela ekuzinzeni okuphelele kwesisekelo, kunciphisa ubungozi bokuhlala noma ukuguquka ngokuhamba kwesikhathi. Ngaphezu kwalokho, ukumelana kwe-granite ukuhuzuka nokuguga kuyenza ibe ukukhetha okuhle kakhulu ezisekelweni ezingaphansi kwethrafikhi enkulu noma ingcindezi yemishini.

Sengiphetha, amapharamitha wobuchwepheshe wesisekelo semishini yegwadle, okuhlanganisa amandla acindezelayo, imodulus yokunwebeka, i-porosity ephansi, nokuminyana okuphezulu, agcizelela ukusebenza kahle kwayo njengento eyisisekelo. Ngokusebenzisa lezi zakhiwo, onjiniyela bangaklama izisekelo zemishini eziqinile neziqinile ezihlangabezana nezidingo zokwakhiwa kwesimanjemanje.
