ADDMIX 389 is a high-performance super plasticizer based on poly-carboxylic ether (PCE) for concrete. The product has been primarily developed for applications in highperformance concrete where the high early strength &highest durability and performance is required.



The hyperplasticiser shall be ADDMIX 389, high range water reducing, Superplasticizer based on polycarboxylic ether formulation. The product shall comply withASTM C494 Type F and shall be free of lignosulphonates, naphthalene salts and melamine formaldehyde when subjected to IR Spectra. The product shall have specific gravity of 1.1& solid contents not lessthan 40% by weight.



  • High performance concrete for durability.
  • Production of Rheodynamic concrete.
  • High early and ultimate strength concrete.
  • High work ability without segregation or bleeding.
  • Concrete containing pozzolans such asmicrosilica, GGBFS, PFA including high volume flyash concrete.
  • Precast & Pre-stressed concrete.


  • Increase in early & ultimate strengths.
  • Elimination of vibration and reduced labor cost in placing.
  • High modulus of elasticity.
  • Improved adhesion to reinforcing and stressing steel.
  • Reduced shrinkage and creep.
  • Better resistance to carbonation and other aggressive atmospheric conditions.
  • Lower permeability - increased durability.
