Nā mea e pili ana i ka hana o ka lehu lele

Nui nā kumu e pili ana i ka hana o ka lehu lele a paʻakikī loa. ʻO nā kumu hoʻomalu koʻikoʻi: ka haku mele ʻana (ka hapa nui o ke aniani); hale aniani; nā hemahema kino a me ke kino o ka wahi ho'ā i loko o ke aniani (me nā mea i hana ʻia ma ka wili ʻana); wai Ka hana o ka mea hoʻoheheʻe kemika; ka puunaue nui o na mea liilii. ʻO ka nui o nā kaʻina hana ma ka laina hana lehu lele, ʻoi aku ka maikaʻi o ka lehu lele i hana ʻia, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai lehu lele. Akā ma keʻano laulā, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana; hoʻokahi kemika, ka mea nui e pili ana i ka helu a me ka hoʻohui ʻana o nā mea ikaika e komo a hoʻoikaika i nā hopena pozzolanic; ʻo ke kino ka mea ʻē aʻe, ka mea nui e pili ana i ke kaʻina hydration a me ka paʻakikī o ka sima ʻO ka hale pōhaku sima i hana ʻia ma hope.

1. Nā mea kemika

No ka mea, ʻo ka ʻāpana aniani silica-alumina ke kumu nui o ka hana olehu lele 'O nā mea e ho'ēmi ai i ka helu o nā kino aniani, e like me ka nui o ka poho ma ka ho'ā a me ka nui o nā māhele crystalline, he mea maika'i'ole i ka hana. Eia kekahi, i ka hoʻokumu ʻana o ka māhele aniani, ʻaʻole like nā kuleana o nā mea like ʻole. ʻO nā oxide ka mea maʻamau i lokolehu lele , a ʻo ia nā mea nui o nā huahana hydration. Eia nō naʻe, ma lalo o nā makahiki like ʻole a me nā kūlana wela, ʻokoʻa ka degere a me ke koʻikoʻi o nā oxides i komo i nā hopena hydration. Eia kekahi laʻana, hiki i ka hao ke hoʻemi i ka helu heheʻe o ka lehu, kahi kūpono i ka hanaʻana i nā microbeads aniani. Eia nō naʻe, no ka mea, ʻaʻole maikaʻi ka nui o ka hao oxide no ka hana ʻana; hiki i ka liʻiliʻi o ka alkali metala oxides ke hoʻoikaika i ka hydration. Hoʻokō ʻia ka hopena, akā i ka wā e hoʻohana ai i ka aggregate ikaika, ʻo ka ʻike kiʻekiʻe o ka potassium a me ka sodium oxides i ka lehu lele e hoʻoikaika i ka hopena o ka aggregate alkaline, a laila e luku ai i ke kūpaʻa o ke koneki; he wahi liʻiliʻi o ka sulfur trioxide i loko o ka lehu lele He mea maikaʻi ia i ka hoʻokumu ʻana i ka silicate calcium hydrated a me ka hoʻokumu ʻana o ka calcium sulfoaluminate (ettringite) i hāʻawi ʻia i ka ikaika mua, akā ʻo ka nui o ka hoʻonui ettringite e hoʻopilikia i ka leo, no laila ka ʻAʻole pono ke kiʻekiʻe o ka sulfur trioxide ma 3%.

2. Nā kumu kino

ʻO nā kumu nui e pili ana i ka hana o ka lehu lele ʻo ia ka morphology particle, microstructure a me nā mea kino ʻē aʻe. No nāʻano likeʻole o ka lehu lele,ʻo ka liʻiliʻi o ka wai e pono ai ke kūlike maʻamau,ʻoi aku ka kiʻekiʻe o ka hana; ʻo ka haʻahaʻa o ke kalapona, ʻoi aku ka kiʻekiʻe o ka hana; ʻo ka liʻiliʻi o ka fineness, ʻoi aku ka kiʻekiʻe o ka hana; in terms of particle morphology, spherical glass in fly ash ʻOi aku ka nui o ka hana o ka lehu lele. Mai ka microstructure ano E, kalehu leleme ke kaulahao pōkole silicon-oxygen tetrahedral structure i oi aku ka hana.

Hiki i ka ʻāpana kiko o ka lehu lele ke hōʻike i ka haku mele a me ke ʻano o ka lehu lele i kekahi ʻano. ʻO nā ʻāpana liʻiliʻi o ka lehu lele, ʻoi aku ka nui o ka ʻili; ʻO ke kino aniani waiwai nui ka calcium he hale paʻa a me kahi ʻāpana liʻiliʻi e pili ana; he nui na kino aniani porous. ʻO nā puka, he nui ka ʻāpana ili kūikawā.
