Technical Data Sheet Declaration Of Performances Safety Data Sheet Description Chryso® Xel 650 is a chloride-free set accelerating admixture designed to promote the early stages of cement hydration, particularly in low-temperature conditions. By accelerating the initial chemical reactions within the cement matrix, it significantly reduces setting time and enables earlier strength development in concrete. The product is especially suited to cold weather concreting, where slower hydration can delay construction processes. By improving early compressive strength, Chryso® Xel 650 helps maintain productivity and supports reliable performance in challenging environmental conditions. Chryso® Xel 650 is suitable for a wide range of applications, including ready-mix, precast, prestressed, and poured concrete. Its compatibility with all cement types and low alkali content make it a flexible solution for different mix designs while maintaining consistent performance. Application areas All cement types Cold weather concreting Ready-mix concrete Poured concrete Prestressed concrete Precast Benefits Accelerates early cement hydration, especially in low temperatures Reduces concrete setting time for faster progression on site Improves early-age compressive strength development Supports cold weather concreting and site productivity Compatible with all cement types for flexible mix design Suitable for ready-mix, precast, prestressed, and poured concrete Chloride-free formulation reduces corrosion risk Low alkali content supports controlled mix performance Packaging 20 L bucket Container of 1000L 215 L Barrel Bulk delivery on request
