Slump Extenders Slump Extenders for Ready Mix Home Concrete Ready-Mix Concrete Speciality Readymix Solutions Slump Extenders 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. Extended Workability Consistent Concrete Quality Improved Transport Flexibility 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. Ready-Mix Concrete Supports consistent concrete performance during transport and placement, helping maintain target workability throughout the delivery process. Large Concrete Pours Provides extended consistency retention for projects requiring long placing times and continuous concrete placement. Urban Construction Projects Helps producers manage traffic delays, restricted site access, and variable delivery schedules without compromising concrete quality. Complex Placement Conditions 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. Products Mid-Range plasticisers/MRWR 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.
