I-Granite iyinto ethandwayo yokwenza izingxenye zomshini ngenxa yokuqina kwayo, ukuqina nokumelana nokuguga.Kodwa-ke, kusengaba khona ukukhubazeka ezingxenyeni zomshini we-granite ezingathinta ikhwalithi nokusebenza kwazo.
Esinye seziphambeko ezivamile ezingxenyeni zomshini we-granite ukuqhekeka.Lezi yizimfantu noma imigqa evela phezulu noma ngaphakathi kwengxenye ngenxa yengcindezi, umthelela noma ukushintsha kwezinga lokushisa.Imifantu ingenza ingxenye futhi ibangele ukuthi yehluleke ngaphambi kwesikhathi.
Esinye isici i-porosity.Izingxenye zomshini we-granite ezinama-porous yilezo ezinamaphakethe amancane omoya noma ama-voids ngaphakathi kwawo.Lokhu kungenza zibe ntekenteke futhi zikwazi ukuqhekeka noma ziphuke ngaphansi kwengcindezi.I-Porosity ingase futhi ithinte ukunemba kobukhulu bengxenye, okuholela ekungalumbeni kahle emishinini.
Isici sesithathu ukuqedwa kwe-surface.Izingxenye zomshini we-granite zingase zibe nokuqedwa kwengaphezulu okungalingani noma okungalungile okungathinta ukusebenza kwazo.Ukuqina kungabangela ukungqubuzana futhi kuholele ekwenyukeni kokuguga nokwephuka kwengxenye.Kungenza futhi kube nzima ukukhweza noma ukuhlanganisa ingxenye ngendlela efanele.
Okokugcina, ikhwalithi ye-granite esetshenzisiwe nayo ingathinta umkhiqizo.I-granite yekhwalithi embi ingase ibe nokungcola noma ukungahambisani okungathinta ubulukhuni bayo, ukuqina nokumelana nokugqoka.Lokhu kungaholela ekushintshweni njalo nasekulungiseni izingxenye zomshini.
Kodwa-ke, kubalulekile ukuqaphela ukuthi lezi zinkinga zingancishiswa noma ziqedwe ngezinqubo ezifanele zokukhiqiza kanye nezinyathelo zokulawula ikhwalithi.Isibonelo, ukuqhekeka kungavinjelwa ngokusebenzisa i-granite yekhwalithi enhle nokulawula izinga lokushisa nokucindezeleka ngesikhathi somshini.I-Porosity ingaqedwa ngokusebenzisa inqubo yokufaka i-vacuum ukugcwalisa i-voids nge-resin noma i-polymer.Ukuphela kwendawo kungathuthukiswa ngokupholisha nokusebenzisa amathuluzi okusika anembe.
Ekugcineni, izingxenye zomshini we-granite ziyindlela ethembekile nehlala isikhathi eside emishinini.Ngokuqinisekisa ukukhiqizwa okufanele kanye nezinyathelo zokulawula ikhwalithi, ukukhubazeka kungancishiswa futhi ukuphila isikhathi eside nokusebenza kwezingxenye kungakhuliswa.
