Slump Extenders

Slump Extenders for Ready Mix

Extended Workability for Greater Placement Flexibility

Chryso® Slump Extenders are designed to maintain concrete consistency and workability for longer periods without compromising performance. Developed for ready-mix concrete applications, the range helps producers manage transportation times, challenging site conditions, and complex placing requirements while maintaining the desired concrete properties.

By extending slump life and supporting rheology control, these admixtures help ensure concrete remains workable from batching through to placement. The range is particularly beneficial for projects requiring extended transport times, large pours, or improved placement flexibility, helping producers deliver consistent quality and performance.

Enhanced Placement and Pumpability

Key Benefits of Chryso® Slump Extenders

  • Maintain concrete workability for longer periods
  • Reduce the need for additional water on site
  • Improve concrete placement and finishing quality
  • Support consistent concrete performance across varying delivery times
  • Helps manage challenges associated with hot weather concreting
  • Enables greater flexibility for ready mix producers and contractors
  • Assists in achieving smoother construction workflows

Chryso® Slump Extenders are used in ready-mix concrete applications where maintaining workability for extended periods is essential. The range supports producers facing long transport distances, complex pours, variable site conditions, or projects with extended placement requirements.

Supports consistent concrete performance during transport and placement, helping maintain target workability throughout the delivery process.

Provides extended consistency retention for projects requiring long placing times and continuous concrete placement.

Helps producers manage traffic delays, restricted site access, and variable delivery schedules without compromising concrete quality.

Maintains workability for challenging pours where additional placement flexibility is required.

Slump extending admixtures can help maintain consistency, improve efficiency and support successful project delivery.

Chryso®Equalis 250

Chryso®Equalis 250 is a rheology extender, based on a new technology developed by CHRYSO’s Research Centre Chryso®Equalis 250 should be used in combination with a (high range) water reducer of the range Chryso®Plast Omega, Chryso®Fluid Optima or Chryso®Fluid Premia.   Chryso®Equalis 250 improves significantly the workability retentions, with very limited effect on the setting time and hardening of the concrete.   Since Chryso®Equalis 250 does not affect significantly the initial workability, it is used to adjust the workability retention: water reduction and initial workability being fine-tuned thanks to the (high range) water reducing admixture. Chryso®Equalis 250 is the perfect solution in case of remote jobsite or heavy traffic, as well as temperature changes.   Chryso®Equalis 250 makes it possible to avoid retempering at the delivery point.   Chryso®Equalis 250 is particularly suited for cements for which workability retention is difficult to get and/or at high temperature. 

Chryso®Equalis 314

Chryso®Equalis 314 is a new-generation water-reducing plasticiser incorporating Chryso’s innovative consistency-extending technology. Developed using advanced hybrid polymer technology, it is designed to improve the stability and workability of fresh concrete without increasing mix water content.   Chryso®Equalis 314 is formulated to deliver consistent fresh and hardened concrete performance across variable binder compositions and cement chemistries. It is intended for use in combination with a high-range water reducer from the Chryso®Omega, Chryso®Optima or Chryso®Premia ranges. The admixture significantly improves consistency and rheology retention, reducing the need for re-tempering at the point of delivery, while having minimal impact on setting time and strength development. It is particularly suited to ready-mix concrete applications involving long transport distances, heavy traffic conditions or temperature variations.
