Densified Silica Fume Rau Concrete Admixture

Densified silica fume yog ib yam khoom ntawm silicon thiab ferrosilicon alloy manufacturing txheej txheem. Nws yog cov hmoov zoo tsim los ntawm amorphous silica hais uas yog me me, nrog qhov nruab nrab particle loj ntawm ib ncig ntawm 0.1 microns. Thaum ntxiv rau pob zeb, nws ua raws li cov khoom sib xyaw uas txhim kho cov khoom ntawm cov pob zeb.

Nta:

densified silica fume yog ib tug heev reactive pozzolan, uas txhais tau hais tias nws reacts chemically nrog calcium hydroxide nyob rau hauv lub xub ntiag ntawm dej los tsim calcium silicate hydrate, lub ntsiab binder nyob rau hauv pob zeb.

Nws muaj thaj chaw siab thiab yog tsim los ntawm cov khoom zoo heev, uas tso cai rau nws los sau cov chaw nruab nrab ntawm cov cement particles thiab tsim kom muaj kev cog lus ntau dua, denser pob zeb.

Nws yog cov hmoov grey uas muaj nyob rau hauv ntau lossis hauv 25kg hnab.

Qhov zoo:

Ua kom lub zog compressive ntawm pob zeb: Densified silica fume tuaj yeem ua kom lub zog compressive ntawm pob zeb nce mus txog 25 feem pua.

Ua kom muaj zog ntawm cov pob zeb: Nws tuaj yeem txo cov permeability thiab ua rau muaj kev tawm tsam tshuaj lom neeg, ua rau cov pob zeb ua kom ruaj khov thiab kav ntev.

Txhim kho kev ua haujlwm: Densified silica fume txhim kho kev ua haujlwm ntawm cov pob zeb los ntawm kev txo cov dej uas xav tau thaum tseem ua haujlwm zoo ib yam, ua rau cov pob zeb muaj zog nrog dej tsawg.

Txo los ntshav thiab cais tawm: Nws pab txo cov ntshav thiab cais tawm, ua kom muaj kev sib xyaw ua ke ntau dua.

Kev siv:

Densified silica fume yog siv los ua ib qho kev sib xyaw hauv cov pob zeb, tshwj xeeb tshaj yog nyob rau hauv kev siv zog thiab kev ua haujlwm siab xws li txuas hniav, qhov, thiab cov tsev siab.

Nws kuj tseem siv tau rau hauv kev txhaj tshuaj, precast qhob, thiab hauv cov ntawv thov uas yuav tsum muaj kev ua haujlwm siab xws li cov qauv hauv hiav txwv thiab cov chaw kho dej khib nyiab.
