Hoʻohana nui ʻia nā ʻāpana Granite i ka ʻoihana hana ʻana no ka mea hāʻawi lākou i ke kūpaʻa kiʻekiʻe a me ka pololei. ʻO nā mīkini ana ʻekolu-hoʻonohonoho (CMM) kekahi o nā mea hana hana he nui e hoʻohana ana i nā ʻāpana granite. ʻO ka hoʻohana ʻana i nā ʻāpana granite i nā CMM e hōʻoiaʻiʻo i nā ana pololei ma muli o ko lākou mau waiwai kūlohelohe e like me ke kiʻekiʻe o ka paʻakikī, ka paʻakikī, a me ke kūpaʻa wela. ʻO kēia mau waiwai e kūpono ai nā ʻāpana granite no nā mīkini ana e pono ai ka pololei kiʻekiʻe a me nā ana pololei.
ʻO kekahi o nā pono koʻikoʻi o ka hoʻohana ʻana i nā ʻāpana granite i loko o nā CMM ʻo ia ko lākou kūpaʻa i ka ʻaʻahu. He pōhaku kūlohelohe paʻa a paʻa ka Granite a ua kaulana ʻia no kona ikaika a me ke kūpaʻa i ka ʻaʻahu. Hiki i nā ʻāpana Granite i hoʻohana ʻia i loko o nā CMM ke kū i nā kūlana hana koʻikoʻi, me nā haʻalulu a me ke kaomi, me ka ʻole o ka hōʻike ʻana i nā hōʻailona o ka ʻaʻahu a i ʻole ka deformation. ʻO ke kūpaʻa ʻana o nā ʻāpana granite e hōʻoiaʻiʻo ʻaʻole pono lākou i nā pani maʻamau, kahi e hōʻemi ai i nā kumukūʻai mālama a hoʻonui i ka manawa hana o ka mīkini.
Eia kekahi, he haʻahaʻa ka mālama ʻana i nā ʻāpana granite. ʻAʻole pono lākou e mālama nui ʻia, a me ka mālama pono a me ka hoʻomaʻemaʻe mau ʻana, hiki iā lākou ke mālama i ko lākou pololei a me ka pololei no nā makahiki. ʻO ka hoʻohana ʻana i nā ʻāpana granite i nā CMM e hōʻoiaʻiʻo ana e mālama ka mīkini i kona pololei, kahi e alakaʻi ai i nā hewa ana liʻiliʻi a me nā hopena hana hou i hoʻomaikaʻi ʻia.
Ma waho aʻe o ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa maikaʻi loa, hāʻawi nā ʻāpana granite i kahi kūpaʻa kūlohelohe i ka deformation i hoʻokumu ʻia e nā loli o ka mahana. ʻO ka coefficient haʻahaʻa o ka hoʻonui ʻana o ka thermal (CTE) o ka granite e hōʻoiaʻiʻo ana e mau ana ka pololei o nā ana me ka nānā ʻole i ka mahana ma ke kaiapuni hana. ʻO ka CTE haʻahaʻa e hana ai i ka granite i mea kūpono no ka hoʻohana ʻana i nā CMM e pono ai nā kaʻina hana ana pololei a me ke kūpaʻa maikaʻi loa.
I ka hopena, ʻo ka hoʻohana ʻana i nā ʻāpana granite i loko o nā CMM e hōʻoiaʻiʻo ana i ka pololei a me ke kūpaʻa kiʻekiʻe, a ʻo ka pono no ka hoʻololi ʻana he liʻiliʻi loa ia. ʻO ke kūpaʻa ʻana i ka ʻaʻahu, ka mālama haʻahaʻa, a me ke kūpaʻa kūlohelohe i ka deformation i hoʻokumu ʻia e nā loli o ka mahana e hana i nā ʻāpana granite i kūpono no ka hoʻohana ʻana i nā CMM, a me nā ʻoihana ʻē aʻe he nui e pono ai nā kaʻina hana hana kiʻekiʻe. ʻO nā pono o nā ʻāpana granite i loko o nā CMM e komo pū me ka pono kiʻekiʻe, ka hoʻomaikaʻi ʻana i ka kaohi maikaʻi, a me ka hoʻemi ʻana i ka downtime, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ka huahana a me ka loaʻa kālā.
