Silica Fume Rau Kev Ua Haujlwm Siab mortars Thiab Grouts
Silica fume yog cov khoom siv pozzolanic zoo heev siv hauv kev tsim cov tshuaj khib nyiab thiab cov khoom ua haujlwm siab. Qhov no ultra-fine, amorphous silica residue yog ib qho khoom los ntawm cov txheej txheem ntawm silicon lossis ferrosilicon alloys. Silica fume yog ib lub zog reactivity enhancer rau cementitious cov ntaub ntawv thiab txhim kho lub zog, durability, thiab workability ntawm mortars thiab grouts.

Khoom Description
Silica fume hais yog me me, nrog rau thaj tsam li ntawm 20 npaug ntau dua li cov cement hais. Qhov no tso cai rau lawv sau cov pores thiab voids hauv pob zeb, uas ua rau cov khoom denser thiab tsawg permeable. Qhov no, nyob rau hauv lem, ua rau kom durability, tsis kam mus tshuaj tua kab mob, thiab puas kuj. Tsis tas li ntawd, nrog lub siab cementitious reactivity, silica fume tsub kom lub zog ntawm kev ua haujlwm siab mortars thiab grouts, ua rau kev ua tau zoo tag nrho.
Tsis tas li ntawd, silica fume kuj yog ib qho cuab yeej tseem ceeb rau kev txo cov teebmeem ntawm thermal cracking. Nws siv tuaj yeem txo qhov tshwm sim ntawm cov pob txha tawg thaum ntxov, uas tshwm sim los ntawm kev ya raws sai sai thiab thermal gradients.
Hauv cov ntsiab lus, qhov sib ntxiv ntawm silica fume rau cov mortars thiab grouts txhim khu lawv cov khoom, ua rau muaj zog dua, ruaj dua, thiab cov ntaub ntawv resistant. Kev siv nws yog ib qho tseem ceeb uas yuav tau xav txog thaum tsim thiab tsim cov khoom siv ua haujlwm siab.

Khoom Description
1.Cov khoom no muaj xws li ultra-fine particles uas yog ob peb zaug me dua cov nplej ntawm cov xuab zeb, uas tso cai rau nws mus sau nyob rau hauv lub qhov khoob ntawm cov xuab zeb thiab cement particle.
2.Ib qho tseem ceeb tshaj plaws ntawm Silica Fume yog nws lub zog compressive siab.
3.Silica Fume kuj tseem tiv taus corrosion, ua rau nws yog ib qho khoom siv zoo heev rau kev siv hauv qhov chaw hnyav.
4. Silica Fume kuj tseem tiv taus corrosion, ua rau nws yog ib qho khoom siv zoo heev rau kev siv hauv qhov chaw hnyav.
