CHRYSO® Optima 249
CHRYSO® Optima 249 is a new generation high range water reducing admixture based on proprietary polymers.
CHRYSO® Optima 249 is formulated specifically to enhance rheology and strengths characteristics of High and Ultra-high Performance Concrete (HPC & UHPC).
CHRYSO® Optima 249 exclusive formulation allows for extreme easiness of use and robustness.
- Provides enhanced workability retention
- Provides increased slump and flowability without increased water content
- Improves finish, placement and pumpability of concrete
- Allows for ultra high strengths performances at all ages
- Improves concrete quality by reducing the water-cement ratio for a given degree of workability
- Proprietary molecule reduces concrete viscosity (stickiness) allowing for easier placement, better finish and enhanced pumpability
- Reduces cracking and shrinkage
- Improves concrete chemical resistance and durability
- Improves cementitious material performance (more psi/lb)
CHRYSO® Optima 249 is recommended for all concrete mixes where significant water reduction, improved cementitious material performance (more psi/lb), improved finishing and enhanced slump retention characteristics are desirable including SCC.
CHRYSO® Optima 249 is especially recommended for use in high performance concrete applications where very good slump or flow retention characteristics and enhanced pumpability are required.
