Lime-pozzolan sima: production me te whakamahi

Ko reira ki ngā tāpiritanga clinker rauemi sima Pozzolan ko te paura puka ki herea āhuatanga, kua hāngai te reira. riro Taumaha hanganga kirihou i runga i te whakapā ki te wai, me te solidifies ki runga ki te whakamaroke.

production

I tipu motuhake hanga o te kotakota-pozzolan sima, te hanga o e titau te tukanga o te huringa tonu. Rerekē enei whakaurunga ahumahi ko e whai ratou te whakamahia he wehenga mo te huri mō te huri me te tāpiritanga whakamaroke. mahi ratou rite matū kohuke māori - gliezh, diatomite, ano taea ki te whakamahi i-hua o te hanga pūngao.

He plurality o matū atu i roto i roto i taua rauemi, rite te sima pozzolan. Te hanganga me te rahi o kai whakaawe nga āhuatanga whakahaere. Hei huri i te wā solidification i roto i huri o gypsum te tāpiri, kia waiho te nui tona kore ake atu i te 3% o te taimaha katoa.

hanganga

huri Tapeke, he te tikanga tino rongonui o hokohoko sima kotakota-pozzolana, kua he āhuatanga motuhake i roto i te puka o huri te clinker ki gypsum me te kohuke āhuatanga kaha i roto i te mira maha motuhake. I mua i mongamonga ka kawea ki te taumata haumākū e hiahiatia ana i roto i te pahū whakamaroke enei kai. E tano ia tapao e te whakanui ake i te ōwehenga o te wahi o tāpiritanga te whakaiti i te utu o te rauemi.

Ko te tairongo ki huringa pāmahana tukanga sima solidification Lime-pozzolana. I pāmahana ki runga ki te 14 nekehanga i āhuatanga te ranunga e te solidification puhoi. whakaritea mutu te tukanga ka te pāmahana ambient ko 5 nekehanga. No te mea o tenei nui fakafaingata'a'ia'i te whakamahi o te rauemi i roto i te wa makariri i roto i te wāhi tuwhera.

I te sima pozzolan taua hopukanga atu nui tere i pāmahana teitei, me te ara ki runga ake i mua sima Portland. Hei whakanui i te mahi o ngā wāhanga hangaia, e taea te pehi e ratou ki te maimoatanga wera atu i te pāmahana i roto i te whānuitanga o 80-90 nekehanga.

Huapai me ngā huakore

sima Pozzolan, e tukua āhuatanga ki te hanga i roto i matū solidification pērā i te konupūmā hydrosilicate hydroaluminate me te rere pānga iti atu i te hunga i hanga i roto i te sima tikanga whakarato ātete nui ki nga pānga o saline me te wai hou. I roto i te painga ko reira utu te tuhituhi i te whai ake:

• āhuatanga pozzolan sima e te hanganga o iti kapiti;
• he taumata tiketike o te adhesion ki nga mea timatanga ngā raima;
• ngāwari whāwhā;
• āhuatanga hononga pai;
• Ko te ranunga pozzolanic hanga te nui nui o te raima moata ranei ki te kohi taua o te rauemi me te tahi atu momo o ngā ranunga.

Otiia kihai i reira kahore drawbacks:

• te hiahia ki te whakamahi i atu o te wai te ine he;
• rokiroki auroa heke te mahi o te matū roto.

He aha koe Kia i matau

Te kore sima e kore e mahi i tetahi kaupapa hanga, i Russia ko te rangatira i roto i te hanga o tenei rauemi. Tetahi o ona rerekētanga i roto i to ratou hanganga hanganga matū no ki te kāwai o silicates, he reira i roto i te hanganga i te puka o te takawai hāorarua te tāpiri. Ka rite ki te pūtake o protrudes clinker sima whakaturia nei o kotakota me paru, puhipuhi mua. mahi te whenua Diatomaceous rite te poke. I hanga i roto i te hanga me te whakamahi o te sima puehu i te rongo auroa ai te whanaketanga Bronchitis me i roto i te wā onge - pneumoconiosis, ngā te apa takawai hāorarua te taikaha, e Kei roto he sima pozzolanic.

Silicosis Ko te ahua nui o pneumoconiosis me riro te nuinga whānui i roto i te whanaketanga kaha o te engineering me ahumahi keri tika ki te meka e pā te hanganga mahi he maha nui o kiripaka puehu. Ko te nuinga noa i roto i te iwi e pā ana ki te tukatuka o ofa'i, te whanaketanga o huna, hanga uku me pūhui whakangutungutu te mate.

Ētahi atu tikanga o te hanga

sima Pozzolan, whakawhirinaki ano i runga i te tukanga, e taea te hanga kahore anake i roto i te tipu, engari ano hoki i roto i te pae hanga ratou te whakamahi i te whakaurunga huri-whakamaroke nei āhuatanga. E maroke ratou tāpiringa kohuke, he whenua me konatunatua ki te nuinga, he reira ano hoki e taea huri tukutahi o nga kai. whakaiti tenei waka popoketanga, kawea anake clinker me kohuke huānga e hua ratou i roto i te rohe hanga. I roto i nga painga o taua kia tuhia he tikanga te taea o te huri i te hanganga o te rauemi korari hanga ki taima noa. Ko te te whakamahi o ngā wāhi motuhake anake i roto i ngā pukapuka nui hanga whakatikaia.

Pozzolan sima: whakamahi

Ko te rauemi tino whakamahia whānuitia whiwhi i roto i te hanga o te raima whakapakaritia me ngā raima raro me te whakamahi raro, e mahi ki te pūkawa me wai hou. Taea te whakamahi mō te fluids me ngā āhuatanga hanganga, taiao e kua āhuatanga e ngā taumata teitei o te haumākū. Ko reira ano hoki te whakamahi noa i roto i waihanga engineering waipēhi titoa vnutrimassivnogo raima.

Whakamahi i roto i ngā hanganga raima teretetiera whāiti e tika ana ki te iti āhuatanga huka ātete, i roto i ngā ki te solidification Polovaisoa rangi. hāngai ana tēnei i runga i whakamaroke nohopuku, i te mea e taea ki te mutu i te tukanga o te solidification ka arahi ki te na'ina'iraa nui. Hoki hanga houhou o ngā āhuatanga hanganga o pozzolan sima, ki te e whakamahia ratou i raro i te hukapapa wā, me te mīti, whakamaroke me te Hydration.

kaha

Pozzolan hanganga sima, āhuatanga, tono e whakarato kaha motuhake o ngā āhuatanga taiwhanga, he roa, e meinga ai e te nui o te konupūmā magnesium i hanga. Hoki te rauemi āhuatanga e te hua roa i roto i te kaha e tika ana ki te whakaiti o te katoa taimaha o te sima, te mea katoa i roto i te tāuru kai atu kupenga. Kōkiri Kia pakeke hydrate tuhia mā te tauhohe i te waikura konupūmā me te silica kaha, te hua kaha hua rauemi rite ki ētahi atu grout sima. Na reira, roa he noho i roto i te taiao hou.

tono Water

Pozzolan sima, e hāngai ana nei i runga i diatomite me Tripoli, kua āhuatanga e nui haere te hiahia wai, ārahi ki wā pōturi o te solidification whakamutunga. Ki te hanga i te nui e hiahiatia ana sima slurry o wai hoki faarahi i runga i te kohuke huānga hohe. kitea Ko tōna whakaiti i roto i te aroaro o tāpiritanga i roto i te hanganga o te tuff me te ara.

Ko te hua i roto i te tono i te wai he houhou no takoha atu te reira ki te kohi nui o tenei momo o te sima whakaritea ki te tahi atu. Ko te tua o te rere pungarehu kore e huri i te nui o te wai e hiahiatia ana mō te ranu. Ka taea te konatunatua reira ki e rua te ranunga raima, me te ki ano sima. E kore e iti te kounga o te rauemi tae noa ki te ka te pungarehu e whakakapi i te wahi.
