While in the HEM system, the powerful mixing of cement and h2o with sand presents dissipation and absorption of Electricity through the mixture and improves shear stresses on the area of cement particles. As a result the temperature with the combination improves by twenty-twenty five diploma of Celsius. This intense mixing serves to deepen hydration process In the cement particles. The nano- sized colloid Calcium Silicate Hydrate (C-S-H) development amplified quite a few instances in evaluating with typical mixing. Consequently the common concrete transforms to Nanoconcrete.
