Effect of silica fume in concrete | Silica fume

The concrete added with silica fume has a high degree of compactness, and the degree of wear of the concrete is very small. We used the ASTM C 779 standard to test the concrete wear resistance. When the concrete strength reaches 76Mpa, the concrete wears 1.4MM in 60 minutes, which is much higher than the reference concrete and has high wear resistance.
