ARS-L505, is a lignosulfonate-based plasticizer and water reducer containing 20% of solid materials, which is specialized for concretes with a water to cementitious materials ratio above 0.5. This product improves dispersion of cement particles through reducing steric hindrance, and thus enhance the pumpability of concrete, which makes it suitable for the use in the precast concrete industry and ready-mixed concretes at moderate temperatures. This admixture is suggested for the production of concretes having the compressive strength of 20 to 30 MPa.


  • Reduce concrete permeability
  • improve initial slump at a certain water to cement ratio
  • Decrease bleeding and segregation of aggregates
  • Enhance pumping performance
  • Reduce water to cement ratio
  • Enhance concrete compressive strength and durability

Consumption order

  • Best time to consume: 5 min after concrete mixing
  • Time required for impact: 10 min after addition
  • Proposed dose: 0.5-1.5% by weight of cement
