Kev piav qhia
Microsilica, tseem hu ua silica fume, yog cov khoom siv los ntawm kev tsim cov hlau silicon thiab ferrosilicon alloys. Nws yog cov khoom siv pozzolanic reactive heev uas yog siv los ua cov khoom siv cementitious ntxiv hauv pob zeb.
Kev siv cov microsilica ua haujlwm siab hauv pob zeb tuaj yeem txhim kho lub zog, ua haujlwm ntev, thiab kev ua haujlwm tag nrho ntawm cov pob zeb. Qhov no yog vim hais tias microsilica muaj thaj chaw siab heev, uas tso cai rau nws ua kom zoo dua nrog cov cement thiab dej hauv cov pob zeb sib tov.

Siv
Microsilica yog siv los ua cov khoom siv cementitious ntxiv rau hauv pob zeb los txhim kho nws lub zog, ruaj khov, thiab kev ua haujlwm tag nrho.
Nws tuaj yeem siv rau ntau yam kev siv pob zeb, suav nrog cov pob zeb muaj zog, kev sib koom ua ke ntawm tus kheej, kev txhaj tshuaj, thiab cov pob zeb ua ntej.
Microsilica kuj tseem siv rau hauv cov ntaub ntawv refractory, ua cov khoom siv hauv cov yas thiab cov roj hmab, thiab hauv kev tsim cov ceramics.
Cov txiaj ntsig
Ua kom muaj zog compressive: Microsilica txhim kho lub zog compressive ntawm pob zeb los ntawm kev sau cov voids hauv cov cement paste thiab ua kom nws ntom.
Ua kom muaj zog ntxiv: Microsilica kuj tseem txhim kho lub zog ntawm cov pob zeb los ntawm kev txo nws cov permeability rau dej thiab lwm yam khoom tsis zoo.
Txhim kho kev ua haujlwm: Microsilica txhim kho kev ua haujlwm ntawm pob zeb los ntawm kev ua kom muaj dej ntau dua thiab yooj yim dua rau cov twj thiab qhov chaw.
Txo cov shrinkage: Microsilica txo qhov shrinkage ntawm pob zeb los ntawm kev txo cov dej xav tau hauv kev sib tov.
