Decorative plate made of Nano concrete with Large-Vitality Mixing (HEM) Nanoconcrete (also spelled "nano concrete"' or "nano-concrete") is a class of elements which contains Portland cement particles which can be no larger than a hundred μm[ninety] and particles of silica no greater than five hundred μm, which fill voids that could in any other case manifest in typical concrete, therefore considerably rising the material's power.
