Boima itseng tsa mabota a konkreiti a itšetlehile ka mofuta lona

E Lejoe maiketsetso e hlahisoang ke ho kopanya metsi, samente le aggregates (lehlohlojane, lehlabathe kapa lehlohlojane), 'me ntshetsa pele solidification bona o bitsoa konkreite.

Ka lintho tse bonahalang mohaho ona o ile oa qala ho sebelisoa mehleng ea boholo-holo ea ho hlophisoa ka konkreiti leng ka nako eo o ne a fapane haholo ho tloha hona joale. Ho na le e ne e le nako eo ka eona o ne a ile a khaotsa ho ka nako e tsa tšebeliso, empa lilemong tsa bo-XIX ile a qapa binders ntjha haeteroliki, tse kang, ho etsa mohlala, Portland samente, 'me mabota a konkreiti a botjha atile ka ea kaho. Ka 60-ogy ea lekholo XIX. E ile ea ntlafala samente thekenoloji difeme, cha matla e ile ea eketseha 'me e ne e sebelisoa e le binder le ka sehloohong la konkreite. Ka motsotso sehlahiswa sena - e mong oa ba thepa ea bohlokoa ka ho fetisisa sebelisoa ka hoo e batlang e likarolong tsohle tsa kaho ea kajeno.

ho amohela joalo, o ile a fumana leboha ho litšobotsi tse latelang:

• mefuta e fapaneng ya thepa e fumanweng ka lebaka la ho se tšoane ka boleng tsa tšebeliso ea thepa Lejoe le binders le litsela tse sa tšoaneng physicochemical le ho e lokisa phetha molao;
• fokotsa ho sebetsa le Remix ka konkreiti, e nang le fetoha le maemo e phahameng le ho lumella ho proizvodnje mefuta e fapaneng mefuta e tsa dibopeho le boholo bo sa tsoarellang, mehaho e phahameng thepa ea mohaho;
• khoneha ka botlalo ho mechanize tshebetso ya ho sebetsa 'moho le ka konkreiti;
• moruo, ka molumo ka 80-90% le bopilwe ka Lejoe aggregates tlhahiso ea sebaka seo.

Tlhahiso ea boleng bo phahameng Remix ka konkreiti ka etsahala feela ka tsebo ea theknoloji e, khetha thepa bokgoni ba itseng boleng le matla a ho a bale karo-karolelano ea bona, ho fumana mekhoa e setaele, liqibi le ho kopanya mekhoa.

Bakeng sa kaho ea mehaho e fapa-fapaneng le boenjiniere sebelisa mefuta e fapaneng ya ka konkreiti (ka ho itšetlehile ka ya kopo). Ho na le makgetha a ho 'maloa bohlokoa, tse behiloeng ka mahlofo lintho tse bonahalang: boima itseng tsa konkreiti s le matla a lona, le mofuta oa binder, morero le serame. The tlhophiso ka sehloohong o entsoe ka boima ba 'mele ba modumo. Ka lebaka leo ho eena, concretes ke haholo leseli, leseli, e boima 'me e eketsehileng e boima.
