Uni Plast NP Advantages

Uni Plast NP is a low cost water reducer, which can be used to get one or combination of benefits

  • As a water reducer: (for increased strength) Reduction in the water cement ratio to maintain designed workability, increased strength. The concrete is also denser with lower permeability.
  • As a workability aid: Increased workability can be achieved by using Uni Plast NP for a given water cement ratio which will increase the flow characteristics of the concrete leading to easy placement, compaction and finishing.
  • Reduction of cement content: Uni Plast NP can be used to reduce cement content to the extent of 8 to 10% by maintaining the original strength specified and workability and reducing the water content required for the given mix.
