Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?
Ntxiv cov hmoov hlau silica rau pob zeb tuaj yeem txhim kho kev ua tau zoo ntawm pob zeb, feem ntau ntawm lub zog, durability thiab impermeability muaj qee yam zoo. Cov hauv qab no yog cov teebmeem tshwj xeeb ntawm hlau silica hmoov rau kev ua haujlwm ntawm pob zeb:
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?1. Ua kom muaj zog
Qhov sib ntxiv ntawm cov hmoov hlau silica tuaj yeem sau cov qhov hws me me hauv cov pob zeb thiab ua lub luag haujlwm ntawm "micro-aggregate", ua rau cov qauv sab hauv ntawm cov pob zeb ntau ntom.
Nyob rau hauv qhov kub thiab txias, silicon nyob rau hauv cov hlau silicon hmoov thiab cov cement hydration cov khoom yuav raug tshuaj lom neeg cov tshuaj tiv thaiv ntxiv (xws li reacting nrog calcium hydroxide los tsim calcium silicate gel), yog li txhim kho lub zog ntawm cov pob zeb, tshwj xeeb tshaj yog thaum ntxov thiab lig. theem.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?2. Txhim kho impermeability
Cov hlau silicon hmoov cov khoom yog zoo thiab muaj cov khoom ntim zoo, uas tuaj yeem ua rau cov capillary pores ntawm pob zeb, txo cov porosity thiab tsim cov qauv ntom.
Qhov ntom ntom no txo cov permeability ntawm cov dej thiab lwm yam corrosive, txhim kho cov permeability ntawm pob zeb, ua rau nws tsim nyog rau underground engineering, Marine ib puag ncig thiab lwm yam siab permeability.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?3. Txhim khu kev ruaj khov
Qhov sib ntxiv ntawm cov hlau silica hmoov txhim kho cov compactness ntawm pob zeb, txo cov yaig ntawm cov khoom tsis zoo (xws li chloride ions thiab carbon dioxide) nyob rau hauv cov pob zeb, thiab ncua kev corrosion thiab carbonization ntawm steel tuav.
Kev ruaj ntseg tshuaj nyob rau hauv pob zeb yog txhim kho, thiab muaj peev xwm tiv thaiv khov-thaw thiab tshuaj lom neeg erosion yog nce, yog li txhim kho lub durability ntawm pob zeb ua qauv.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?4. Txhim kho kev ua haujlwm
Hlau silica hmoov tuaj yeem ua rau kom muaj peev xwm ua haujlwm thiab ua kom muaj dej ntawm cov pob zeb, yog li txhim kho kev tsim kho.
Vim hais tias cov khoom yog zoo, cov hlau silicon hmoov yog sib npaug zos rau hauv cov pob zeb, txo cov viscosity thiab segregation, yooj yim rau cov twj tso kua mis thiab ncuav, thiab conducive rau kev tsim kho ntawm loj ntim thiab siab fluidity pob zeb.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?5. Txo cov dej-cement piv yuav tsum tau
Qhov sib ntxiv ntawm cov hmoov metallic silica pab kom tau txais qhov xav tau fluidity yam tsis tas yuav nce cov dej, yog li txo cov dej-cement piv ntawm cov pob zeb. Cov cuab yeej no tuaj yeem txo qhov pores hauv cov pob zeb, ntxiv kev txhim kho lub zog thiab impermeability.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?6. Txhim kho qhov kub thiab txias
Hlau silicon hmoov tswj kev ruaj ntseg nyob rau hauv qhov kub thiab txias ib puag ncig, tuaj yeem txhim kho cov cua sov ua haujlwm ntawm cov pob zeb hauv qhov kub thiab txias, haum rau cov qauv tsim nrog hluav taws kub, xws li cov qhov, qhov chaw nres tsheb hauv av, thiab lwm yam.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?Nco tseg
Tus nqi ntawm cov hlau silicon hmoov ntxiv yuav tsum tsim nyog, ntau dhau tuaj yeem ua rau shrinkage thiab tawg ntawm pob zeb.
Vim tias qhov loj me me ntawm cov hlau silicon hmoov, cov hmoov av hmoov av yuav tsum tau tswj nyob rau hauv cov txheej txheem ntawm kev sib xyaw thiab kev thauj mus los, thiab kev tiv thaiv tsim nyog yuav tsum tau ua.
Rau qee qhov sib xyaw, nws yuav tsum tau kho qhov sib piv ntawm cov cement thiab lwm cov khoom sib xyaw kom tsim nyog kom tsis txhob ua rau muaj teeb meem tshuaj lom neeg lossis teeb meem kev tsim kho.
Dab tsi yog qhov cuam tshuam ntawm kev ntxiv hlau silica hmoov rau pob zeb?Saum toj no
Raws li kev ua tau zoo ntawm cov khoom siv, hlau silica hmoov tuaj yeem txhim kho lub zog, impermeability thiab durability ntawm pob zeb thaum ntxiv rau qhov tsim nyog, tshwj xeeb tshaj yog nyob rau hauv kev xav tau kev tsim kho thiab kev siv engineering. Txawm li cas los xij, nws yog ib qho tsim nyog yuav tsum tswj hwm qhov ntau npaum li cas thiab sib xyaw ua ke kom ntseeg tau tias kev txhim kho ntawm tag nrho cov kev ua tau zoo ntawm pob zeb thiab kev ua haujlwm ntawm kev tsim kho.
