Tuam Tshoj txoj kab muaj cov tawv nqaij tawv yog tsuas yog tailings, yoov tshauv, thee-tawg slag thiab desulfurization gypsum. Kev npaj ntawm lub tsev cov ntaub ntawv los ntawm cov khoom siv khib nyiab tau nyiam ntau dua thiab ntau dua. Cov kws tshawb nrhiav tau txhim kho cov txiaj ntsig ntawm cov khoom siv hauv cov ntaub ntawv kev txhim kho hauv tsev thiab kev tshawb fawb thiab kev siv tshuab. Nyob rau tib lub sijhawm, ntau lub teb chaws tau muab cov kev cai txhawb nqa kev lag luam, yog li txhim kho cov khoom siv khib nyiab, yog li txhim kho cov khoom siv khib nyiab rau ib puag ncig rau ib puag ncig. Raws li cov chaw tsim khoom ntawm hlau tailings sib tsoo zeb, pebHlau tailings Ntsug Cov Menyuam Zeb Tau siv dav hauv cov hlau tailings xuab zeb sib tsoo lub tsev cov khoom siv ua kom meej. HCMILLING (GUILIN Hongcheng) yuav qhia cov thev naus laus zis ntawm kev npaj cov khoom siv hauv tsev los ntawm cov hlau tailings.

1. Xam Cement Clinker

Hlau Tailing yog cov nplua nuj nyob hauv cov hlau keeb, uas tuaj yeem hloov cov hmoov hlau li cov khoom siv rau cov avas Clinker ntau lawm. Kev hlawv cov cement clinker nrog limestone, quartz xuab zeb thiab hlau xuab zeb thiab tus nqi sib xyaw ua ke yuav txwv tsis pub txo cov mov xis. Tam sim no, tus nqi ntawm cov hlau tailings siv rau calcining Maas Clinker tsuas yog kwv yees li 15%. Nws yog qhov nrawm los tsim cov cuab yeej tshiab thiab thev naus laus zis los txhim kho cov hlau hlau thiab ua kom cov khoom lag luam kom zoo.

2. Qhob sib sau ua ke

Lub siab tawv ntawm cov hlau tailings feem ntau yog los ntawm sab hauv quartz theem, uas nws qhov loj me me yog ze rau cov xuab zeb thiab khoom siv xuab zeb, thiab tuaj yeem sib xyaw ua pob zeb ua kev sib sau ua ke. Cov pob zeb nrog 28d zog ntawm txog 40mpa tuaj yeem npaj los ntawm kev siv hlau tailings nrog particle loj tsawg dua 1 hli los hloov cov dej xuab zeb kom zoo. Raws li kev ua kom zoo ntawm kev sib sau ua ke, kev siv cov duab hlau ua ke ua ke, tab sis kuj tseem muaj kev sib sau ua ke ntawm cov hlau uas muaj xuab zeb thiab cov xuab zeb uas muaj ntau dua conducive rau kev tswj ntawm cov qhob ua zoo. Raws li cov txheej txheem hauv kev muaj kev txhawj xeeb tam sim no, txhawm rau txhim kho cov hlau rov qab tau txais cov ntaub ntawv rov qab, uas yog qhov nyuaj kom tau raws li cov qauv coarse thiab siv rau cov pob zeb sib sau ua ke.

3. Qhob Vineal admixture

Cov ntxhia Eslixtures yog tsuas yog tsim cov amorphous siliceous, calorareous siliceous, caloretous siliceous, calcareous silassous, calcareous silassous, calcareous cov ntaub ntawv, uas ua si ib qho khoom siv tseem ceeb hauv kev txhim kho lub compactness, impermabeability thiab durability ntawm qhob. Lawv tuaj yeem txo cov kev noj kom xis mas thiab txo cov cua sov ntawm cov dej kub tib lub sijhawm. Yog li ntawd, nws yog ib qho tseem ceeb kom pom cov ntxhia minektures tshiab rau kev tsim kho kom ruaj khov ntawm kev lag luam cement. Cov ntxhia pob zeb loj hauv cov hlau tailings yog feem ntau quartz, uas muaj cov phooj ywg me me hauv lub xeev ntuj. Yuav ua li cas txhawm rau txhim kho cov "pozzolanic kev ua haujlwm" ntawm cov hlau tailings tau dhau los ua lub ntsiab lus tseem ceeb ntawm cov neeg tshawb nrhiav tam sim no. Raws li ib qho ntawm feem ntau siv cov hau kev rau kev ua kom cov hlau tinings, kev sib tsoo tshuab tuaj yeem txo cov tshuab hlau ua kom muaj qhov tsis xws luag thiab ua kom muaj kev cuam tshuam yas ntxiv. Cov kev tshawb fawb qhia tau tias kev sib tsoo txhua yam tuaj yeem txhawb cov pozzolanic kev ua haujlwm ntawm cov khoom loj ntawm cov kab laum nyob hauv cov hlau tailings. Raws li cov particle qhov loj ntawm cov mineral cov minerals txo qis, quartz tuaj yeem ua rau amorphous hydrated calcium silicate gel thiab ettringite siv lead ua thiab ettringite siv lead ua thiab lwm yam khoom siv hydration. Cov kev tshawb fawb qhia tau hais tias thaum cov neeg kho tshuab sib tsoo yog ntau dua 40min, qhov sib txawv me me yog tso tawm, thiab cov kev sib xws yog maj txhim kho. Nyob rau hauv lub anhydrite hlau tailing calhium oxide system, cov pob zeb sib tsoo tuaj yeem sib xyaw nrog 30% los npaj 32,5 cement. Nyob rau hauv cov xwm txheej ntawm cov dej qis nrog cov hmoov av uas muaj peev xwm txhawb kev cug cug dua, thiab txhim kho lub zog thaum ntxov. Qhov nce ntawm thaj chaw saum npoo av uas tsis muaj cov txiaj ntsig pom tseeb ntawm kev txhim kho nws cov kev ua haujlwm ntsuas; Kev hloov pauv ntawm kev kho qhov kub tau tuaj yeem nce qhov kev ua si ntawm qhov ntsuas kev ua si thaum pib qhov ntsuas ntawm qhov kev ua si nyob rau theem qeeb (28D). Rau cov hlau tailings slag Composite system, qhov kev ua haujlwm ntsuas tuaj yeem txhim kho los ntawm kev txhim kho tshuab sib tsoo, yog li txhim kho lub durability ntawm kev ua vaj tse. Kev siv dej txo tus neeg siv dej kom tsim nyog tuaj yeem nce cov ntsiab lus ntawm cov duab hlau hlau hauv cov pob zeb zoo tib yam los ntawm 30% mus rau 40%. Cov hlau tailings sib tsoo tuaj yeem txhim kho kev sib tsoo ua tau zoo los ntawm nws tus kheej cov nyhuv, yog li ua rau cov kev ua si pozzolanic ntawm cov hlau tailings. Los ntawm kev ua kom zoo ntawm cov qauv hlau, slag, clinker thiab gypsum compositimitious Mementum Cegy, ultra-siab ua ke nrog kev ua tau zoo sib ntsib lub teb chaws tus qauv tuaj yeem npaj tau.
