CHRYSO® AMA 620 EL is an activator especially formulated to increase early age and 28 days strengths. CHRYSO® AMA 620 EL is both a highly concentrated grinding aid and activator that allows to maximise SCM content, while maintaining early and late strengths at low dosages.

  • Improves significantly early age and 28 days strengths.
  • Decreases percentage of clinker in cement to reduce CO2 emissions and production costs.
  • Increases mill production (10% to 25%) depending on the efficiency of the equipment and the characteristics of the material to be ground.
  • Reduces grinding energy costs at same fineness of grinding.
  • Improves bulk density and powder flow characteristics, therefore improving the conditions of storage, pneumatic transport and packaging in bags.
  • Improves cement particle size distribution and consequently cement hydration.
  • Reduces coating tendencies.
  • Reduces plastic shrinkage (initial set).
  • Provides a positive pack-set effect.
Domains of application
  • Aluminate cement grinding.
  • Cement grinding according EN 197-1 standards, type I through V specifications.
