Specialist admixtures for consistent performance, even in complex pours

The CHRYSO®Optima 200 and 300 ranges are high-performance superplasticisers designed to enhance workability and reduce water content without delaying setting times. These admixtures allow contractors and manufacturers to achieve consistent, high-quality results, even in large-volume or complex pours.

By combining fluidity maintenance with water reduction, the ranges are particularly suited for fluid to self-compacting concrete, high-performance concrete (HPC), and very high-performance concrete (VHPC). They are also ideal for applications requiring rapid strength development, making them flexible solutions for demanding construction projects.

Furthermore, CHRYSO®Optima 200 and 300 optimise mix designs, producing cohesive, robust concrete while improving efficiency, reducing water usage, and supporting both early-age and 28-day strength development.

Key Benefits of CHRYSO®Optima 200 & 300

 

Engineered for efficiency, adaptability, and performance, the CHRYSO®Optima 200 and 300 ranges deliver:

  • Extended Workability Retention: Maintains fluidity for longer periods, supporting complex pours and extended transport.
  • High Water Reduction: Reduces water content to optimise concrete strength and durability.
  • Rapid Strength Development: Supports early-age and 28-day strength for fast-track construction.
  • Versatile Applications: Suitable for self-compacting, HPC, VHPC, and fluid concretes across a variety of projects.

The CHRYSO®Optima 200 and 300 ranges offer advanced performance for high-demand construction projects. They maintain workability while reducing water content, ensuring cohesive, easy-to-place concrete that meets precise specifications.

Extended fluidity allows for reliable placement across complex pours:

  • Maintains workability over extended periods

  • Facilitates quality control and site management

  • Ideal for long transport or large-volume pours

Optimising the water-to-cement ratio enhances concrete strength and durability:

  • Reduces water content for stronger mixes

  • Supports high-performance and very high-performance concretes

  • Improves mix cohesion and finish quality

Enables rapid development of mechanical properties:

  • Early-age and 28-day compressive strength optimised

  • Supports fast-track construction schedules

  • Compatible with demanding concrete formulations

Flexible and adaptable for a wide range of concrete applications:

  • Fluid, self-compacting, HPC, and VHPC concretes

  • Performs reliably under diverse site conditions

  • Integrates seamlessly with existing mix designs
