Iiparamitha zobuchwephesha besiseko somatshini wegranite.

 

I-Granite, ilitye elitshisayo elisetyenziswa ngokubanzi, lidume ngokuhlala kunye nokomelela, liyenza ibe yinto efanelekileyo kwisiseko soomatshini kwiiprojekthi ezahlukeneyo zokwakha. Ukuqonda iiparitha zobugcisa beziseko zoomatshini begranite kubalulekile kwiinjineli kunye nabayili bezakhiwo ukuqinisekisa imfezeko yesakhiwo kunye nokuphila ixesha elide.

Enye yezona parameters zobugcisa zegranite ngamandla ayo acinezelayo, aqhele ukuqala ukusuka kwi-100 ukuya kwi-300 MPa. La mandla aphezulu acinezelayo avumela igranite ukuba imelane nemithwalo ebalulekileyo, iyenze ilungele oomatshini abanzima kunye nezixhobo. Ukongezelela, i-granite ibonisa i-porosity ephantsi, ngokubanzi phakathi kwe-0.1% ukuya kwi-0.5%, enegalelo ekuchaseni ukungena kwamanzi kunye nemozulu yekhemikhali, iphucula ngakumbi ukufaneleka kwayo kwiziseko zoomatshini.

Enye iparameter ebalulekileyo yimodyuli ye-elasticity, ethi i-granite ibe malunga ne-50 ukuya kwi-70 ye-GPa. Le propati ibonisa ukuba zininzi kangakanani izinto eziya kuguqulwa phantsi koxinzelelo, ukubonelela ngeembono ekusebenzeni kwayo phantsi kwemithwalo eguquguqukayo. I-coefficient ephantsi yokwandiswa kwe-thermal ye-granite, malunga ne-5 ukuya kwi-7 x 10 ^ -6 / ° C, iqinisekisa ukuba igcina ingqibelelo yesakhiwo kunye nokuguquguquka kweqondo lokushisa, okwenza kube yinto ethembekileyo yokukhetha iziseko kwiindawo ezahlukeneyo zezulu.

Uxinaniso lweGranite, phakathi kwe-2.63 ukuya kwi-2.75 g/cm³, nalo ludlala indima ebalulekileyo kuyilo lwesiseko. Uxinzelelo oluphezulu lunegalelo ekuzinzeni ngokubanzi kwesiseko, ukunciphisa umngcipheko wokuhlaliswa okanye ukutshintshwa kwexesha. Ngaphaya koko, ukuxhathisa kwegranite kwi-abrasion kunye nokunxiba kuyenza ibe lolona khetho lubalaseleyo kwiziseko eziphantsi kwetrafikhi enzima okanye uxinzelelo lomatshini.

Ukuqukumbela, iiparamitha zobugcisa beziseko zoomatshini begranite, kubandakanywa amandla acinezelayo, imodyuli yokuqina, i-porosity ephantsi, kunye noxinzelelo oluphezulu, igxininisa ukusebenza kwayo njengento esisiseko. Ngokusebenzisa ezi zakhiwo, iinjineli zinokuyila iziseko zoomatshini ezomeleleyo nezizinzileyo ezihlangabezana neemfuno zolwakhiwo lwangoku.
