94% Undensified Microsilica (실리카 연료) 94유
94% 결정되지 않은 실리카 연료 (94유) is a highly effective supplementary cementitious material derived from the byproduct of silicon and ferrosilicon alloy production. It contains approximately 94% amorphous silica (sio2) and possesses exceptional physical and chemical properties that make it a valuable addition to various construction materials, especially concrete and cement-based products.
With a low bulk density ranging from 250 에게 350 kg/m3, 94% Undensified Silica Fume is lightweight and easy to handle, resulting in reduced transportation costs. Its specific surface area, typically between 15,000 and 30,000 M2/kg, allows for a high pozzolanic reactivity that enhances the mechanical and durability properties of the final products.
