Water demand and workability of the concrete are significantly influenced by particle size distribution. Present in the solid system. Typical concrete mixtures do not have an optimum particle size distribution and this accounts for the undesirably high water requirement to achieve certain workability.
Secondly, to plasticize a cement paste for achieving an acceptable consistency, much larger amounts of water than necessary for the hydration of cement.
However, there is the possibility of water reduction higher than 20% incase of the use of our micro silica. This is because fine particles of our micro silica get absorbed on the oppositely charged surfaces of cement particles and prevent them from frocculation.
The cement particles are thus effectively dispersed and will trap large amounts of water meaning that the system will have a reduced water requirement to achieve a given consistency. The more the fineness the more is the number of contacts among the particles and hence the more is the resistance to flow.
