Fig. 1: Traditional vs. high performance concrete.
The specific surface area of such admixtures can be increased by grinding techniques such as ball milling or high energy ball milling whereby the latter technique is able to reduce the grain size down to the nanometer regime. The result is a high performance concrete (HPC) with increased strength (Fig.1).
