Granite ali ndi kachulukidwe kwambiri, zomwe zimapangitsa kuti kutentha kwake kukhale bata. Izi zikutanthauza kuti mbale za granite sizingakhudzidwe ndi kusintha kwa kutentha kapena chinyezi, kuwonetsetsa kulondola ndi kulondola panthawi yoyezera. Kukhazikika kwazinthu kumathandiza kupewa kusinthika, ngakhale m'malo okhala ndi kutentha kosinthasintha.

3. Compressive Mphamvu ya Granite

Granite yomwe imagwiritsidwa ntchito popanga zida zoyezera molondola iyeneranso kuwonetsa mphamvu zopondereza kwambiri. Mphamvu imeneyi imatsimikizira kuti granite imatha kupirira kupanikizika ndi mphamvu zomwe zimaperekedwa panthawi ya miyeso popanda kumenyana kapena kusweka.

Mzere wowonjezera wowonjezera wa granite ndi 4.61 × 10⁻⁶/°C, ndipo mlingo wake wa kuyamwa madzi ndi wocheperapo 0.13%. Zinthuzi zimapangitsa granite kukhala yabwino kwambiri popanga mbale za granite pamwamba ndi zida zina zoyezera. Mphamvu yopondereza kwambiri komanso kuyamwa kwamadzi otsika kumatsimikizira kuti zinthuzo zimasunga zolondola komanso zosalala pakapita nthawi, ndikukonza kochepa komwe kumafunikira.

Mapeto

Ma granite okha omwe ali ndi mawonekedwe oyenera akuthupi-monga kuuma kokwanira, mphamvu yokoka yeniyeni, ndi mphamvu zopondereza-zingagwiritsidwe ntchito kupanga mapepala apamwamba a granite apamwamba ndi zida zoyezera. Zidazi ndizofunikira pakuwonetsetsa kulondola kwanthawi yayitali, kulimba, komanso kugwira ntchito bwino kwa zida zanu zoyezera mwatsatanetsatane. Posankha miyala ya granite yopanga zida zoyezera, ndikofunikira kuwonetsetsa kuti zopangirazo zikukwaniritsa zofunikira izi.
