Ultraval SR: ultra fast & ultra resistant

A Portland cement with an outstanding mechanical performance, especially at early ages. This allows surfaces to be put into immediate service, ensuring a high increase in productivity, particularly in the precast concrete sector. 

It is ultra-fast and ultra-resistant, developing a strength of 25-50 MPa in a time of just 4 to 8 hours, as opposed to the 28 days needed for conventional cements.

It is a stand-alone product. No accelerators are required for it to work in extreme temperature conditions or aggressive environments, such as marine ones.  

It is ultra-customizable. Because it is the most versatile cement on the market, different dosages can be used to suit specific requirements, thus ensuring cost-effective results.
