Aplikasi


  • High-Performance Concrete: White microsilica is used to produce high-performance concrete with improved strength, daya tahan, and resistance to chemical attack.
  • Refractory Materials: Due to its high purity and low iron content, zirconium silica fume is an essential ingredient in the production of refractory materials such as bricks, castables, and monolithic linings.
  • White Cement: White microsilica is used to produce high-purity white cement, which has applications in architectural and decorative concrete.
  • Ceramics: Zirconium silica fume is used in the production of advanced ceramics, such as zirconia-based ceramics, where it can act as a sintering aid and enhance the final properties of the product.
  • Repair Materials: White microsilica can be used in repair materials to improve bonding, strength, and durability.
  • Oil Well Cementing: Zirconium silica fume can be added to oil well cement to enhance its performance by improving its mechanical properties, reducing permeability, and increasing resistance to chemical attack in the harsh downhole environment.
  • Precast Concrete: White microsilica can be used in the production of precast concrete elements, where it contributes to improved strength, daya tahan, and surface finish.
  • Shotcrete and Gunite: Zirconium silica fume can be added to shotcrete and gunite mixtures to enhance their strength, adhesion, and resistance to cracking, making them suitable for applications in tunneling, mining, and slope stabilization.
  • Self-Compacting Concrete (SCC): White microsilica’s ability to improve workability and rheological properties makes it suitable for use in self-compacting concrete, which requires minimal vibration and compaction during placement.
  • Fiber-Reinforced Concrete: The addition of zirconium silica fume to fiber-reinforced concrete can enhance the bond between fibers and the cementitious matrix, leading to improved mechanical properties and durability.

Biaya silika fume dipengaruhi oleh banyak faktor, seperti kandungan SiO2, biaya transportasi logistik, biaya tenaga kerja, dll. Umumnya, harga silika fume berkisar dari $150 ke $800 per metrik ton. Namun, harga terkadang melebihi kisaran ini untuk kualitas tinggi, produk khusus atau untuk pesanan kecil. Karena kebutuhan yang berbeda, yang berarti harganya berubah, jadi kami tidak dapat memberikan penawaran online. Kami akan mengirimkan Anda kutipan terperinci setelah Anda mengirimkan kebutuhan Anda kepada kami.

Silica fume dan fly ash keduanya merupakan bahan pelengkap semen yang dapat meningkatkan kinerja beton. Asap silika terdiri dari partikel silika amorf yang sangat halus, sedangkan fly ash merupakan produk sampingan pembakaran batubara dan terdiri dari partikel bulat kecil dari bahan anorganik. Partikel asap silika jauh lebih kecil dibandingkan partikel abu terbang, dan umumnya dianggap sebagai pozzolan yang lebih reaktif dibandingkan abu terbang. Silica fume dikenal dapat meningkatkan kuat tekan beton pada usia dini, sedangkan fly ash biasanya digunakan untuk meningkatkan kekuatan dan daya tahan beton dalam jangka panjang. Pilihan material mana yang akan digunakan akan bergantung pada aplikasi spesifik dan persyaratan kinerja beton yang digunakan.
