94% Mikrosilika Tak Terdensifikasi (Asap Silika) 94kamu
94% Asap Silika yang Tidak Didensifikasi (94kamu) 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 ke 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 Dan 30,000 m2/kg, allows for a high pozzolanic reactivity that enhances the mechanical and durability properties of the final products.
