Ultrafine GGBFS Fly Ash Blend (D50=14.73μm) | Micro-Fine Mineral Powder

The ultra-fine particle size is the cornerstone of its performance: particles smaller than 32μm account for 100% of the product, with 38.44% falling in the 3-10μm range. This fine particle distribution fills the nanoscale and microscale voids between cement grains, creating a denser, more homogeneous microstructure that significantly improves concrete’s impermeability, strength, and durability. In fresh concrete, it enhances fluidity and cohesiveness, reducing bleeding and segregation, making it ideal for self-compacting concrete (SCC) and high-strength concrete (HSC) applications where precise workability is critical.

Performance data confirms the impact of this ultra-fine grading: at a 30% dosage, the 28-day compressive strength reaches 56.2 MPa, with 90-day strength climbing to 67.7 MPa—outperforming both pure cement and coarser mineral admixtures. The fine particles also accelerate the pozzolanic reaction, leading to faster early strength gain while maintaining long-term performance. For projects requiring exceptional surface finish, such as architectural concrete, or superior durability, such as nuclear power plants or coastal infrastructure, YL Ultra-Micro Grade Composite Powder is the premium choice, offering technical superiority that justifies its investment.
