The nano particles would be evenly distributed among the larger particles of mineral admixtures and with such fine dispersion even a lower content of cement should be able to provide desired binding of aggregates and admixture particles generating required strength and performance. Nano sized particles of cement on account of their large surface area would also hydrate at a much faster rate accelerating strength development. Further, the nano particles of cement and nano sized

In the case of Nano minerals, this is due to their unique electromagnetic load and the extremely small particle size. Particle size is an important factor for good mineral absorption, because a fundamental physical law states that the smaller the particle, the greater the relative particle surface. It is this surface that the body uses to break down and absorb nutrients. The larger the surface, the better nutrients
