Ubuninzi benkunkuma eqinileyo yemizi-mveliso yaseTshayina ubukhulu becala yimisila, uthuthu lwempukane, igangue yamalahle, i-smelting slag, i-slag yamalahle kunye negypsum ye-desulfurization.Ukulungiswa kwezinto zokwakha ezivela kwinkunkuma eqinileyo kuye kwatsala ingqalelo engakumbi.Abaphandi baye baphucula umlinganiselo obanzi wokusetyenziswa kwenkunkuma eqinileyo kwishishini lezinto zokwakha ngokuphucula kunye nophando kunye nophuhliso lwezixhobo kunye nobuchwepheshe.Kwangaxeshanye, amazwe awahlukahlukeneyo akhuphe imithetho nemimiselo exhasayo ukuvuselela umdla wamashishini wokusebenzisa inkunkuma eqinileyo, ngaloo ndlela ephucula impembelelo yenkunkuma eqinileyo kwimizi-mveliso kwindalo esingqongileyo ukusa kumlinganiselo othile.Njengomvelisi wentsimbi yokusila ii-tailings, yethuintsimbi yokusila nkqo roller isetyenziswe ngokubanzi kwisanti yokusila izixhobo zokwakha ezibanzi zeprojekthi.I-HCMilling(Guilin Hongcheng) iya kwazisa itekhnoloji yokulungiselela izinto zokwakha ezivela kwiintsimbi zentsimbi.

1. Iklinka yesamente ene-calcined

Umsila wentsimbi utyebile ngokwentsimbi, enokungena endaweni yomgubo wentsimbi njengemathiriyeli ekrwada yokuvelisa iklinka yesamente.Ukutshisa i-clinker ye-cement kunye ne-limestone, isanti ye-quartz kunye ne-iron tailings njengezinto eziluhlaza kunokunciphisa ngokufanelekileyo ubushushu be-calcination kunye neendleko zesamente, kodwa isixa sokuxuba silinganiselwe, kwaye isixa sokuxuba ngokugqithiseleyo siya kunciphisa kakhulu amandla e-samente.Okwangoku, ubungakanani bentsimbi yokubilisa esetyenziselwa ukubala iklinka yesamente malunga ne-15% kuphela.Kungxamisekile ukuba kuphuhliswe izixhobo ezitsha kunye nobuchwepheshe obutsha ukuphucula ubungakanani bentsimbi yentsimbi kunye nokuqinisekisa umgangatho weemveliso zesamente.

2. Concrete aggregate

Ukuqina okuphezulu kweentsalela zentsimbi kuvela ikakhulu kwisigaba sangaphakathi sequartz, esinobungakanani bamasuntswana asondele kwisanti yendalo yomlambo kunye nesanti eyenziweyo, kwaye inokuxutywa kwikhonkrithi njengeaggregate.Ikhonkrithi enamandla angama-28d amalunga ne-40MPa inokulungiswa ngokusebenzisa iintsalela zentsimbi ezinobungakanani besuntswana elingaphantsi kwe-1mm ukuze kufakwe indawo yesanti yomlambo yendalo njengeaggregate ecolekileyo.Ngokusekwe ekulungelelaniseni ukuhlelwa kweaggregate, ukusetyenziswa komxube wentsimbi kunye nesanti eyenziwe ngomatshini njengeaggregate ayinakuhlangabezana kuphela neemfuno zekhonkrithi yemathiriyeli, kodwa inozinzo olungcono kunolo lwentsimbi kunye nesanti yendalo yomlambo, engaphezulu. luncedo kulawulo lomgangatho obambekayo.Ngokubhekiselele kwinkqubo yangoku yokuxhamla, ukwenzela ukuba kuphuculwe izinga lokubuyisela isinyithi, amasuntswana amasuntswana entsimbi ayacotha kwaye acoleke ngakumbi, okunzima ukuhlangabezana nomgangatho we-aggregate erhabaxa kwaye isebenze kwikhonkrithi eqhelekileyo.

3. Concrete mineral admixture

I-Mineral admixtures iqulethwe kakhulu nge-amorphous siliceous, i-calcareous kunye ne-aluminium, edlala indima ebalulekileyo ekuphuculeni ukubumbana, ukunyanzeliswa kunye nokuqina kwekhonkrithi.Banokunciphisa ukusetyenziswa kwe-cement kunye nokunciphisa ukushisa kwe-hydration ngexesha elifanayo.Ngoko ke, kubalulekile ukufumana imixube emitsha yezimbiwa kuphuhliso oluzinzileyo loshishino lwesamente.Isigaba seminerali esiphambili kwi-iron tailings idla ngokuba yi-quartz, enomsebenzi omncinci we-pozzolanic kwimeko yendalo.Indlela yokuphucula "umsebenzi we-pozzolanic" weentsimbi zentsimbi ibe ngumxholo oyintloko wabaphandi bangoku.Njengenye yeendlela eziqhelekileyo ezisetyenziselwa ukusetyenziswa kweentsimbi zentsimbi, ukugaya ngoomatshini kunokunciphisa amandla okusebenza kweentsimbi zentsimbi kunye nokuvelisa iziphene ezininzi ze-lattice kunye nokuguqulwa kweplastiki.Uphando lubonisa ukuba ukugaya ngoomatshini kunokuvuselela umsebenzi we-pozzolanic wezigaba zeminerali eziqhelekileyo kwimisila yentsimbi.Njengoko i-particle ye-particle ye-mechanical minerals iyancipha, i-quartz inokusabela nge-Ca (OH) 2 kwi-samente slurry ukuvelisa i-amorphous hydrated calcium silicate gel kunye ne-crystal ettringite kunye nezinye iimveliso ze-hydration.Uphando lubonisa ukuba xa i-mechanical grinding ingaphezulu kwe-40min, i-angle ebukhali yeentsimbi zensimbi iyancipha ngokucacileyo, iincinci ezincinci ezincinci zibonakaliswe, kwaye ukufana kuyaphuculwa ngokuthe ngcembe.Kwi-anhydrite iron tailing calcium oxide system, i-siliceous iron tailing ye-mechanical grinding ingaxutywa kunye ne-30% ukulungiselela i-samente ye-32.5.Phantsi kwemeko yomlinganiselo we-binder yamanzi aphantsi, umgubo wentsimbi ocolekileyo unokukhuthaza ngokubonakalayo ukugalelwa kwangaphambili kwentlama yesamente edityanisiweyo, wenze ubume bepore bodaka buqine ngakumbi, kwaye buphucule amandla okuqala.Ukunyuka kwendawo ethile yendawo yeentsimbi zentsimbi ayinayo impembelelo ecacileyo ekuphuculeni isalathisi somsebenzi wayo;Ukutshintsha kweqondo lokushisa lokunyanga kunokunyusa kakhulu isalathisi somsebenzi kwinqanaba lokuqala (7d), kodwa kunempembelelo encinci kwisalathisi somsebenzi kwinqanaba lokugqibela (28d).Kwinkqubo ye-iron tailings slag composite, isalathisi somsebenzi sinokuphuculwa ngokuphucula indlela yokugaya, ngaloo ndlela kuphuculwe ukuqina kwekhonkrithi.Ukusetyenziswa ngokufanelekileyo kwe-arhente yokunciphisa amanzi kunokunyusa umxholo wentsimbi yentsimbi kwikhonkrithi eqhelekileyo ukusuka kwi-30% ukuya kwi-40%.Ukusila kwentsimbi kunokuphucula ukusebenza kakuhle ngokusila ngesiphumo sako, ngaloo ndlela kuvuselele umsebenzi we-pozzolanic wokujikeleza kwentsimbi.Ngokwandisa umlinganiselo wentsalela yeentsimbi, i-slag, iklinka kunye ne-gypsum composite cementitious materials, i-ultra-high performance concrete with performance meets the performance standard inokulungiswa.
