ʻO ka limestone he pōhaku sedimentary, i haku nui ʻia me ka calcium carbonate a me ka magnesium carbonate.ʻO kāna kumu nui, ʻo ia ka hana ʻana i ka ʻili one.ʻO nā ʻāpana pōhaku a me ka pauka pōhaku i hana ʻia ma ke kaʻina hana a me ka hana ʻana i lilo i huelo pōhaku.Hoʻopili ʻia nā huelo limestone a lilo i pauka limestone ewili wili pōhaku.Hiki ke hoʻohana ʻia e like me ka hoʻohui ʻana a me nā ʻāpana prefabricated e hoʻonui i ka hoʻohana ʻana i nā ʻāpana pōhaku.Ma ke ʻano he mea hana o limestonewili palaoamīkini, HCMilling(Guilin Hongcheng) e hoʻolauna i ka noi olimestonewili palaoa mīkini e hana i ka pauka limestone.

ʻO ka pauka mineral limestone e pili ana i nā ʻāpana pauka me ka nui o nā ʻāpana liʻiliʻi ma mua o 0.075mm (i wehewehe ʻia i loko o ka hydraulic concrete me ka nui o nā ʻāpana liʻiliʻi ma mua o 0.16mm) i hana ʻia i ka wā o ka hana ʻana o ke one aggregate.ʻO nā ala hoʻohana nui:

(1) ʻO ka lepo limestone i loko o ka pauka mineral e like me ka hoʻohui ʻana: Ua aʻo ʻia ka hoʻohana ʻana i ka pauka mineral limestone i loko o ka ʻoihana ʻenehana no ka manawa lōʻihi.Ma ke ʻano he mea nui o nā huelo, pehea e hoʻohana ai i ka pauka oka limestone e like me ka hoʻohui ʻana i ka ʻiʻo i lilo i wahi wela a me ka ulu ulu ʻana i ka ʻoihana ʻoihana home.ʻO ka pauka limestone he mea hoʻohui inert.Ma ke ʻano he hui hoʻohui no ka ʻuala, ʻike ʻia ka maikaʻi a me ka hiki ke hoʻokō ʻia ka pauka limestone: ʻo ka mea mua, hiki i ka hoʻohui ʻana o ka pauka limestone ke hoʻolalelale i ka hydration o ka sima;ʻO ka lua, ʻo nā ʻāpana o ka limestone ore pauka ka hopena a me ka hopena hoʻopiha.ʻAʻole hiki iā ia ke hoʻonui wale i ka wai o ka hui ʻana, hoʻomaikaʻi i ka helu ʻana o ka ʻōnaehana cementitious, akā hoʻomaikaʻi hoʻi i ke ʻano o ka pore o ka pahu;ʻO ke kolu, he hopena ikaika ka pauka limestone.I kēia mau makahiki i hala iho nei, ua hoʻopuka ʻo Kina i nā kūlana kūloko a me ka ʻāina, i hōʻoia a hoʻopaʻa ʻia i ka hoʻohana ʻana i ka pauka limestone i kumu waiwai.Ma ke ʻano he mea hoʻohui paʻa, ʻo ka lepo limestone i loko o ka pauka mineral he mākeke ākea a maikaʻi hoʻi nā pono pilikanaka a me ka hoʻokele waiwai i ka wā lōʻihi.

(2) Ka hoʻomākaukau ʻana i nā mea hoʻohui i hana mua ʻia ma ka wili ʻana i ka limestone i loko o ka pauka mineral: ʻO ka ʻōnaehana mea prefabricated hou nā mea maikaʻi o ka wikiwiki o ke kūkulu ʻana, ka maʻalahi o ka mālama ʻana, ka mālama ʻana i nā mea, ka maikaʻi o ke ʻano, ka lōʻihi maikaʻi, ka hoʻemi ʻana i ka hana pulu ma ka pūnaewele, a palekana kaiapuni.Ma ke kahua o nā mea i hana mua ʻia, hiki ke hoʻohana ʻia ka nui o ka pauka mineral limestone i nā limestone tailings e like me nā mea hoʻohui a me nā sima.Pono ka Standard for Quality Control of Precast Concrete Components (DB11/T1312-2015) i ke koho ʻana i nā mea hoʻohui mineral e like me ka limestone mineral pauka no ka precast concrete, pono kāna hana e hoʻokō i nā koi o nā kūlana kūpono.Ua hōʻike kekahi mau haʻawina e hiki i ka pauka limestone ke hoʻomaikaʻi maikaʻi i ka fluidity a me ka anti-separation o ke kaʻa i ka hana ʻana i nā mea hoʻoheheʻe ʻole a me ka hoʻopaʻa pono ʻana i nā ʻāpana precast, a loaʻa ka hopena i ka hoʻoheheʻe ʻia ʻana, e hoʻonā i nā pilikia o ka lawa ʻole o nā lako maka.Ma waho aʻe o ka pauka limestone i ʻōlelo ʻia ma luna nei, hiki ke hoʻohana ʻia ka dolomite a me ka pauka granite me nā waiwai like me ka limestone e like me ka hoʻohui ʻana i ka ʻuala a me ka sima.

Ma waho aʻe o ka noi i ka ʻoihana hana, hiki ke hoʻohana ʻia nā mines limestone kiʻekiʻe e hoʻomohala i nā huahana kiʻekiʻe e like me ka calcium carbonate, ka pauka calcium kiʻekiʻe no ka flux, ka pauka limestone no ka desulfurization i nā mea kanu wela.ʻAʻole hiki ke hoʻokaʻawale ʻia kēia mau noi mai ke kākoʻo olimestonewili palaoa mīkini.E like me ka mea hana olimestonewili palaoamīkini, HCMilling(Guilin Hongcheng) hana i ka limestone wili wili mīkini lako e like melimestone Raymondmīkini wili, pōhaku ʻeleʻele kūpaʻamīkini wili palaoa, limestone ultra-finewili palaoamīkini, etc. Hāʻawi ia i ke kākoʻo lako maikaʻi no ka hana ʻana a me ka hoʻohana ʻana i ka pauka limestone, a hiki ke hana i ka 80-2500 mesh limestone pauka.Loaʻa ka ʻike nui o ka pāhana limestone i ka hoʻolālā a me nā hihia kūʻai he nui.

Inā loaʻa iā ʻoe kekahi mau koi kūpono, e ʻoluʻolu e kelepona mai iā mākou e aʻo i nā kikoʻī lako o limestonewili palaoa mīkini.
