Silica Fume (Micro Silica)
VALO Ultra-Silica is an ultra-fine pozzolanic material, composed of amorphous silica produced by blast furnaces as a by-product of the production of silicon metal or ferro silicon alloys.
Main ingredient: amorphous glassy Si02, content 80-95%. It' s an Ultra-fine material, average only 0.15 micron, Smaller than cement particle 80-100 times.
VALO Ultra-Silica can be used in all concrete products. Such as concrete, grouts, mortars, and fiber-cement products. It is produced in conformance with the ASTM C1240 specifications.
