 Related to improved particle packing, high energy milling of ordinary Portland cement (OPC) clinker and standard sand, produces a greater particle size diminution with respect to conventional OPC and, as a result, the compressive strength of the refined material is also 3 to 6 times higher (at different ages).Steel is a widely available material that has a major role in the construction industry.The use of nanotechnology in steel helps to improve the physical properties of steel.
