Loaʻa nā papa granite mai nā papa kinikini ma lalo o ka honua. Ma hope o nā miliona o nā makahiki o ka ʻelemakule ʻana, ua kūpaʻa loa ko lākou ʻano, e hoʻopau ana i ka pilikia o ka deformation ma muli o nā loli mahana maʻamau. ʻO kēia mea granite, i koho pono ʻia a ua hoʻāʻo ʻia i ke kino koʻikoʻi, he mau kristal maikaʻi a me kahi ʻano paʻakikī, me ka ikaika compressive o 2290-3750 kg/cm² a me ka paʻakikī o 6-7 ma ka unahi Mohs.
1. Ke kālele nui nei i ka pololei paʻa a me ka maʻalahi o ka mālama ʻana, hōʻike nā papa granite i kahi microstructure maikaʻi, kahi ʻili laumania, pale i ke komo ʻana, a me ka haʻahaʻa o ka ʻoʻoleʻa.
2. Ma hope o ka ʻelemakule kūlohelohe lōʻihi, hoʻopau nā papa granite i nā pilikia kūloko, e hopena ana i kahi mea paʻa a ʻaʻole hiki ke hoʻololi ʻia.
3. Kūpaʻa lākou i nā waikawa, alkalis, corrosion, a me ka magnetism; kūpaʻa lākou i ka makū a me ka popo, e maʻalahi ai ka hoʻohana a me ka mālama ʻana. Loaʻa iā lākou kahi coefficient hoʻonui linear haʻahaʻa a ʻaʻole i hoʻopilikia iki ʻia e ka mahana.
4. ʻO nā hopena a i ʻole nā kalai ma ka ʻili hana e hana wale i nā lua, me ka ʻole o nā kualono a i ʻole nā ʻūlū, ʻaʻohe ona hopena i ka pololei o ke ana ʻana.
5. Hana ʻia nā papa granite mai nā papa kinikini ma lalo o ka honua. Ma hope o nā miliona o nā makahiki o ka ʻelemakule ʻana, noho paʻa loa ko lākou ʻano, e hoʻopau ana i ka pilikia o ka deformation ma muli o nā loli o ka mahana. ʻO ka granite, i koho pono ʻia a hoʻāʻo pono ʻia, e kaena ana i nā kristal maikaʻi a me kahi ʻano paʻakikī. Hiki i kona ikaika compressive i 2290-3750 kg/cm², a hiki i kona paʻakikī i 6-7 ma ka unahi Mohs.
