Hydramax® 1609

Hydramax 1609

 

An Ultra high-performance hydration enhancing admixture containing a high-range superplasticiser.

 

Hydramax 1609 is an ultra high-performance liquid admixture engineered typically for precast concrete applications. Formulated with a powerful blend of advanced chemicals, it dramatically enhances the hydration efficiency of Portland cement — unlocking superior strength, durability, and consistency in finished concrete products.

 

Traditionally, concrete hydrates 60 – 70% of cement particles. Hydramax 1609 raises that up to 95%, transforming the concrete rheology during hydration to deliver enhanced material performance and efficiency.

 

Whether you’re aiming to reduce production times, increase strengths, or boost overall product quality, Hydramax 1609 offers a smart, reliable solution for modern concrete production, where a high-range superplasticiser is required.

Why Choose Hydramax 1609?

 

Hydramax 1609 is a next-generation admixture that boosts Portland cement hydration up to 95%, delivering outstanding performance, production, and environmental benefits.

 

Designed to optimise Portland cement hydration, Hydramax 1609 allows you to refine your mix design for the outcomes that matter most to you: strength, speed, appearance, durability, production or environmental needs.
