Deliver Extended Workability for Demanding Concrete Projects

Chryso®Tard is a range of set-retarding admixtures designed to extend workability and provide greater flexibility during concrete production and placement. The Chryso®Tard admixture range helps manage setting behaviour by slowing cement hydration, making it particularly suitable for applications that require extended transport, placing, or finishing times.

Extended workability

Controlled set retardation

Hot weather suitability

Flexible concrete production

Key Benefits of Chryso®Tard:

  • Extended placing time: Provides greater flexibility for concrete transport, handling, and placement.
  • Improved project efficiency: Helps maintain workable concrete for longer during demanding pours.
  • Reduced risk of cold joints: Supports more continuous placement across larger concrete elements.
  • Suitable for challenging conditions: Helps manage concrete production in warmer temperatures and complex site situations.
  • Broad material compatibility: Suitable for use with a wide range of cementitious systems.
  • Supports concrete performance: Concrete continues to develop strength following the retarded setting period.

Chryso®Tard is suited to concrete applications where additional working time can improve production, transport, and placement efficiency.

Extended workability helps maintain concrete quality during transport and placement, particularly when delivery distances vary.

Suitable for pours that require longer placement periods. Additional working time helps support a more continuous operation.

Concrete can set more rapidly in elevated temperatures. Set retardation helps provide greater control during production and placement.

Ideal where sequencing, logistics, or site access demands additional flexibility from the concrete mix.

Suitable for use with a variety of cementitious systems used in modern concrete production, including the incorporation of supplementary cementitious materials.

The Chryso®Tard admixture range helps concrete producers and contractors maintain workability for longer while improving placement flexibility. Its set-retarding technology supports efficient concrete production across a wide range of construction applications.
