Nano-engineering of cement-based materialsNano-engineering, or nanomodification, of cement is a quickly emerging field. Synthesis and assembly of materials in the nanometer scale range offer the possibility for the development of new cement additives such as novel superplasticizers, nanoparticles, or nanoreinforcements.
VIRINA Nano Steel has a grain size of ASTM 11-12. ASTM 11 has a density of 1 200 000 grains/mm³. This compares to a density of 23 000 grains/mm³ of an ASTM 7 high chrome grinding ball. This 52x improvement in grain structure results in a VIRINA grinding ball that has significant improvement in strength and ductility.
