Kukhazikika ndi kusanthula kukhazikika kwa maziko a granite.

 

Granite, mwala wachilengedwe womwe umagwiritsidwa ntchito kwambiri, umadziwika chifukwa cha kulimba kwake komanso kukhazikika kwake, zomwe zimapangitsa kuti ukhale chisankho chabwino kwambiri pa ntchito zosiyanasiyana zomangira. Kusanthula kulimba ndi kukhazikika kwa maziko a granite ndikofunikira kwambiri pomvetsetsa momwe amagwirira ntchito pansi pa mikhalidwe yosiyanasiyana yachilengedwe ndi katundu.

Granite ndi mwala wa igneous womwe umapangidwa makamaka ndi quartz, feldspar, ndi mica, zomwe zimathandiza kuti ukhale wolimba komanso wokana kugwedezeka. Pofufuza kulimba kwa maziko a granite, zinthu zingapo zimagwira ntchito, kuphatikizapo kapangidwe ka mchere, ma porosity, ndi kupezeka kwa ming'alu kapena kusweka. Makhalidwe amenewa amatsimikizira momwe granite ingapirire bwino zochitika zakuthupi ndi zamankhwala, monga kuzizira ndi kusungunuka, mvula ya asidi, ndi kusweka.

Kusanthula kukhazikika kwa granite kumayang'ana kwambiri kuthekera kwa granite kusunga umphumphu wake pansi pa katundu wosiyanasiyana, kuphatikizapo mphamvu zosasunthika komanso zosinthasintha. Izi ndizofunikira kwambiri pakugwiritsa ntchito monga kumanga misewu, komwe maziko a granite amakhala ngati maziko. Mainjiniya nthawi zambiri amachita mayeso kuti awone mphamvu yokakamiza, mphamvu yodula, ndi kusinthasintha kwa granite, kuonetsetsa kuti imatha kuthandizira kulemera kwa magalimoto ndikupewa kusinthika pakapita nthawi.

Komanso, kufunika kuganizira za momwe miyala ya granite ingakhudzire chilengedwe. Zinthu monga kusinthasintha kwa kutentha, kuchuluka kwa chinyezi, komanso kukhudzidwa ndi mankhwala zingakhudze momwe miyala ya granite imagwirira ntchito kwa nthawi yayitali. Kusamalira ndi kuyang'anira nthawi zonse kungathandize kuchepetsa mavuto omwe angakhalepo, kuonetsetsa kuti miyala ya granite imakhalabe yolimba komanso yolimba nthawi yonse ya moyo wawo.

Pomaliza, kusanthula kulimba ndi kukhazikika kwa maziko a granite ndikofunikira kwambiri kuti zitsimikizire kuti zikugwira ntchito bwino pantchito zomanga. Pomvetsetsa makhalidwe a granite ndi zinthu zomwe zimakhudza magwiridwe antchito ake, mainjiniya amatha kupanga zisankho zodziwikiratu zomwe zimawonjezera moyo wautali komanso kudalirika kwa nyumba zomangidwa pa maziko a granite.
