Kukhazikika komanso kukhazikika kwa maziko a granite.

 

Granite, mwala wachilengedwe womwe umagwiritsidwa ntchito kwambiri, umadziwika chifukwa cha kukhazikika kwake komanso kukhazikika kwake, zomwe zimapangitsa kukhala chisankho chabwino pazomanga zosiyanasiyana. Kuwunika kwa kukhazikika ndi kukhazikika kwa maziko a granite ndikofunikira pakumvetsetsa momwe amagwirira ntchito pansi pazikhalidwe zosiyanasiyana komanso katundu.

Granite ndi mwala woyaka moto womwe umapangidwa makamaka ndi quartz, feldspar, ndi mica, womwe umathandizira kuti ukhale wamphamvu kwambiri komanso kukana kuzizira. Pofufuza kulimba kwa maziko a granite, pali zinthu zingapo zomwe zimagwira ntchito, kuphatikizapo mchere, porosity, ndi kukhalapo kwa ming'alu kapena fractures. Makhalidwe amenewa amatsimikizira kuti miyala ya granite ingapirire bwino momwe nyengo ikuyendera komanso kusintha kwa nyengo, monga kuzizira, mvula ya asidi, ndi ma abrasion.

Kusanthula kukhazikika kumayang'ana pa kuthekera kwa granite kusunga umphumphu wake pansi pa katundu wosiyanasiyana, kuphatikiza mphamvu zosasunthika komanso zosunthika. Izi ndizofunikira makamaka pakupanga misewu, pomwe maziko a granite amakhala ngati maziko. Mainjiniya nthawi zambiri amayesa kuti awone kulimba kwamphamvu, kumeta ubweya, ndi modulus ya elasticity ya granite, kuwonetsetsa kuti imatha kuthandizira kulemera kwa magalimoto ndikukana kupunduka pakapita nthawi.

Komanso, kukhudzidwa kwa chilengedwe pazigawo za granite kuyenera kuganiziridwa. Zinthu monga kusinthasintha kwa kutentha, kuchuluka kwa chinyezi, ndi kukhudzana ndi mankhwala zingakhudze ntchito ya nthawi yaitali ya granite. Kusamalira nthawi zonse ndi kuyang'anitsitsa kungathandize kuchepetsa zovuta zomwe zingatheke, kuonetsetsa kuti maziko a granite amakhala okhazikika komanso okhazikika pa moyo wawo wonse.

Pomaliza, kuwunika kwa kukhazikika ndi kukhazikika kwa maziko a granite ndikofunikira kuti zitsimikizire kuti zikuyenda bwino pantchito yomanga. Pomvetsetsa mawonekedwe a granite ndi zinthu zomwe zimathandizira magwiridwe ake, mainjiniya amatha kupanga zisankho zomwe zimakulitsa moyo wautali komanso kudalirika kwa nyumba zomangidwa pamaziko a granite.
