ULTRA-RAPID CEMENT
Ultraval SR
Ultra-rapid and ultra-strong in aggressive environments
THE PRODUCT
Ultraval SR
Ultra-rapid and ultra-strong in aggressive environments
It is the Portland-type cement with the highest mechanical performance in the world, especially at early ages, allowing the immediate commissioning of works and achieving substantial productivity increases, especially in the precast industry.
It is Ultra-Rapid and Ultra-Strong, offering strengths of 25–50 MPa in 4 to 8 hours compared to the 28 days of other conventional cements.
It requires no accelerating additives to work in extreme temperature conditions and in aggressive environments such as marine ones. A perfect substitute for silica fume, surpassing its performance at early ages. It is the cement that best activates pozzolans.
As the most flexible and versatile cement on the market, the most suitable and cost-effective mix designs can be developed for the works in which it is used.
UltraVal SR: solves any project requirement in aggressive environments.
