Imfucumfucu eqinile yezimboni yaseShayina ngokuyinhloko iyimisila, umlotha wezimpukane, i-ganggue yamalahle, i-smelting slag, i-slag ekhishwa ngamalahle kanye ne-desulfurization gypsum.Ukulungiswa kwezinto zokwakha ezivela kumfucumfucu oqinile kuye kwadonsa ukunakwa okwengeziwe.Abacwaningi baye bathuthukisa izinga eliphelele lokusebenzisa imfucuza eqinile embonini yezinto zokwakha ngokwenza ngcono nokucwaninga nokuthuthukiswa kwemishini nobuchwepheshe.Ngesikhathi esifanayo, amazwe ahlukahlukene akhiphe imithetho nemithethonqubo esekelayo ukuze avuse umdlandla wamabhizinisi wokusebenzisa imfucumfucu eqinile, ngaleyo ndlela enze ngcono umthelela wemfucumfucu yezimboni endaweni ezungezile ngezinga elithile.Njengomkhiqizi wensimbi yokugaya izinsimbi, yethuizinsimbi zensimbi mpo roller isigayo isetshenziswe kabanzi kuphrojekthi ebanzi yokusetshenziswa kwensimbi yokugaya isihlabathi sokugaya izinto zokwakha.I-HCMilling(Guilin Hongcheng) izokwethula ubuchwepheshe bokulungisa izinto zokwakha kusuka kumasila ensimbi.

1. I-Clinker kasimende ene-calcined

Umsila wensimbi unothile ngensimbi, engangena esikhundleni sempushana yensimbi njengempahla eluhlaza yokukhiqiza iklinka usimende.Ukushisa i-clinker kasimende nge-limestone, isihlabathi se-quartz nensimbi njengezinto zokusetshenziswa kunganciphisa ngempumelelo izinga lokushisa lokubala kanye nezindleko zikasimende, kodwa inani lokuxuba lilinganiselwe, futhi inani lokuxuba ngokweqile lizonciphisa kakhulu amandla kasimende.Njengamanje, inani lezinsalela zensimbi ezisetshenziselwa ukubala i-clinker kasimende lilinganiselwa ku-15%.Kuyaphuthuma ukuthuthukisa imishini emisha kanye nobuchwepheshe obusha ukuze kuthuthukiswe inani lensimbi futhi kuqinisekiswe izinga lemikhiqizo kasimende.

2. Inhlanganisela kakhonkolo

Ukuqina okuphezulu kwezinsalela zensimbi ikakhulukazi kuvela esigabeni se-quartz sangaphakathi, ubukhulu bezinhlayiyana zaso buseduze nesihlabathi somfula esingokwemvelo kanye nesihlabathi esikhiqiziwe, futhi singaxutshwa kukhonkolo njengenhlanganisela.Ukhonkolo onamandla angama-28d acishe abe ngu-40MPa angalungiswa ngokusebenzisa insimbi yensimbi enosayizi wezinhlayiyana ezingaphansi kuka-1mm ukuze kuthathelwe indawo isihlabathi somfula esingokwemvelo njengesihlanganisi esihle.Ngokusekelwe ekuthuthukiseni ukuhlelwa kwe-aggregate, ukusetshenziswa okuyinhlanganisela kwezinsimbi zensimbi nesihlabathi esenziwe ngomshini njengeqoqo akukwazi nje ukuhlangabezana nezidingo zikakhonkolo wezinto zokwakha, kodwa futhi kunokuqina okungcono kunokwensimbi nesihlabathi somfula wemvelo, okungaphezu kwalokho. okusiza ekulawuleni izinga likakhonkolo.Ngokuphathelene nenqubo yamanje yokuhlomula, ukuze kuthuthukiswe izinga lokutholwa kwensimbi, izinhlayiya zensimbi ziya ziba ngcono nakakhulu, okunzima ukuhlangabezana nezinga lokuhlanganisa amaholo futhi zisebenza kukhonkolo evamile.

3. Concrete mineral admixture

Izingxube zamaminerali ikakhulukazi zakhiwe nge-amorphous siliceous, i-calcareous kanye ne-aluminium materials, edlala indima ebalulekile ekuthuthukiseni ukubumbana, ukungakwazi ukungena kanye nokuqina kokhonkolo.Bangakwazi ukunciphisa ukusetshenziswa kukasimende futhi banciphise ukushisa kwe-hydration ngesikhathi esifanayo.Ngakho-ke, kubalulekile ukuthola izixube zezimbiwa ezintsha ukuze kuthuthukiswe imboni kasimende.Isigaba samaminerali esiyinhloko ku-iron tailings ngokuvamile i-quartz, enomsebenzi omncane we-pozzolanic esimweni semvelo.Indlela yokuthuthukisa "umsebenzi we-pozzolanic" wezinsimbi zensimbi uye waba isihloko esiyinhloko sabacwaningi bamanje.Njengenye yezindlela ezivame ukusetshenziswa kakhulu zokwenza kusebenze izinsimbi zensimbi, ukugaya ngomshini kunganciphisa amandla okusebenza ezinsalela zensimbi futhi kukhiqize ukukhubazeka okwengeziwe kwe-lattice kanye nokuguqulwa kwepulasitiki.Ucwaningo lubonisa ukuthi ukugaya ngomshini kungashukumisa umsebenzi we-pozzolanic wezigaba zamaminerali ezijwayelekile emisileni yensimbi.Njengoba usayizi wezinhlayiyana zamaminerali agaywe ngomshini wehla, i-quartz ingasabela nge-Ca (OH) 2 kudaka lukasimende ukuze kukhiqizwe ijeli ye-amorphous hydrated calcium silicate kanye nekristalu ye-ettringite neminye imikhiqizo ye-hydration.Ucwaningo lubonisa ukuthi lapho ukugaya ngomshini kungaphezu kwe-40min, i-engeli ebukhali yensimbi yensimbi iyancipha ngokusobala, izinhlayiya ezincane eziningi ziyaboniswa, futhi ukufana kuyathuthukiswa kancane kancane.Kuhlelo lwe-anhydrite iron tailing calcium oxide, umsila wensimbi wesiliceous wokugaya ngomshini ungaxutshwa no-30% ukulungisa usimende ongu-32.5.Ngaphansi kwesimo sesilinganiso esiphansi se-binder yamanzi, i-iron tailings powder enhle ingakhuthaza ngokuphawulekayo ukugeleza kwangaphambi kwesikhathi kokunamathisela kukasimende oyinhlanganisela, yenze ukwakheka kwembotshana yodaka kuhlangane kakhudlwana, futhi kuthuthukise amandla okuqala.Ukwanda kwendawo ethile yendawo yezinsimbi zensimbi akunawo umthelela osobala ekuthuthukiseni inkomba yayo yomsebenzi;Ukushintsha kwezinga lokushisa lokwelapha kungakhuphula kakhulu inkomba yomsebenzi ekuqaleni (7d), kodwa kube nomthelela omncane kunkomba yomsebenzi ekupheleni kwesigaba (28d).Ohlelweni lwe-iron tailings slag composite, inkomba yomsebenzi ingathuthukiswa ngokuthuthukisa indlela yokugaya, ngaleyo ndlela kuthuthukiswe ukuqina kokhonkolo.Ukusetshenziswa okunengqondo kwe-ejenti yokunciphisa amanzi kungakhuphula okuqukethwe kwezinsimbi zensimbi kukhonkolo evamile kusuka ku-30% kuya ku-40%.Ukugaya insimbi kungathuthukisa ukusebenza kahle kokugaya ngomphumela wako siqu, ngaleyo ndlela kushukumise umsebenzi we-pozzolanic wensimbi.Ngokwandisa isilinganiso sensimbi, i-slag, i-clinker kanye ne-gypsum composite cementitious materials, ukhonkolo osebenza kakhulu osezingeni eliphezulu nohlangabezana nokusebenza kungalungiselelwa izinga likazwelonke.
