Ultra-High Performance Concrete requires precise mix designs to achieve compressive strengths exceeding 150 MPa. Our zirconia white microsilica enhances particle packing density and pozzolanic reactivity, crucial for developing superior UHPC formulations.

Silica fume (microsilica) is a highly reactive pozzolanic additive whose ultra-fine particle size enables it to refine pore structure, improve fiber–matrix bonding, and enhance durability in GFRC and precast concrete elements. In GFRC systems, carefully dosed silica fume improves flexural strength, reduces permeability, and mitigates microcracking, thereby extending service life. This article reviews mechanisms, mixes, and best practices for using silica fume in GFRC / precast concrete applications.

Silica fume is an ultrafine by-product from the production of silicon metal or ferrosilicon alloys.
Its extremely small particle size and high amorphous silica content give it exceptional pozzolanic reactivity and densification properties.
