Guide to Using Silica Fume in Precast/Prestressed Concrete

Silica fume concrete with an HRWR is more cohesive and sticky than conventional concrete. Once again, this cohesiveness is due to its fine particle content. If the silica fume concrete contains superplasticizers, both the shear resistance and the cohesiveness of the concrete will be reduced, and improved flow will result. Silica fume concrete
