Multi-Purpose Ground Crystalline Silica
SILVERBOND®
In demanding construction environments, performance failures aren’t just inconvenient; they can also increase costs and contribute to delays. When you’re formulating cementitious systems, epoxy grouts or insulation materials, you need a filler you can trust to perform under pressure, in every condition, and in any mix.
Covia’s SILVERBOND® meets that challenge. Manufactured from high-purity quartz and engineered for consistency, SILVERBOND is a chemically inert, thermally stable and nonreactive ground silica designed to deliver strength, stiffness and durability without interfering with chemical systems or degrading in harsh conditions.

Going to the Extreme
Concrete is the most widely used material in construction because of its structural performance, but concrete deterioration is a major challenge in regions that experience extreme weather conditions. Secondary cementitious materials can be critical for concrete durability, longevity, cost, workability, strength and as a mitigation method to reduce alkali-silica reactions that lead to premature concrete failure.
High Temperatures
Although some fillers break down when exposed to extreme heat, SILVERBOND doesn't. Its thermal stability and chemical inertness make it an ideal choice for fire-retardant materials, high-performance concretes and heat-resistant industrial products, where reliable performance under sustained high temperatures is critical.
Freezing Temperatures
In cold climates and freeze-thaw environments, fillers that absorb moisture can compromise the durability of the material. SILVERBOND’s low porosity and consistently uniform grading help prevent cracking, shrinkage and material degradation—keeping structures strong even in sub-zero conditions.
Alkali-Silica Reactions
Alkali-silica reactions (ASRs) are a major cause of cracking and premature failure in concrete. SILVERBOND’s high purity and chemical stability significantly reduce the risk of ASRs, supporting long-term durability in concrete and precast applications, especially in projects where longevity is non-negotiable.
