ADDMIX 240 is a high range water reducing, super plasticiser for medium and high grade concretesa.  ADDMIX 240 is composed of sulphonated naphthalene polymers specially designed to allow considerable reduction of mixing water while maintaining control on extend of set retardation. ADDMIX 240 is preferred admixture for triple blend binder system based high performance concrete (HPC) mixes or mixes containing micro silica or metakaolin.



  • Ready mixed concrete
  • Pumped concrete
  • Mixes requiring >20% water reductions
  • Concrete containing Silica fume/ Metakaolin
  • Congested/complex reinforced sections
  • Pre-cast concrete production
  • Long-distance transporting
  • Low water/binder ratio mixes


  • Good dispersion even in mixes with high fines
  • Reduced thermal peaks and permeability
  • High workability for longer periods
  • Lower pumping pressure
  • Increased ease in finishing concrete
  • Resistance to segregation even at high workability
  • Extended setting with longer workability
  • Reduced water content for a given workability
  • Higher ultimate strengths with Improved durability
  • Reduced shrinkage and creep
