The best concrete in class B for concreting pavements could be this one, called Extensia: http://www.lafarge-na.com/Extensia_Datasheet_FR.pdf
properties after 28 days are better, compared to the expensive EdenCrete enriched concrete: Compression Strength 70MPa, Flexural Strength 6 MPa. According to Lafarge:
_{EXTENSIA® CONCRETE IS DESIGNED FOR CONSTRUCTING SLABS AND INDUSTRIAL FLOORS SUBJECT TO HEAVY LOADS DUE TO TRAFFIC OR STORAGE. For surface areas up to 400m2, this avoids having to use joints, which are costly and unattractive, and reduces the risk of cracking. This is because joints are the weak points of concrete floors, where cracks appear over time and need reinforcing. The specific formulation of Extensia® makes the preparation, implementation and removal stages of worksites easier. The result is a considerable time saving of around 40% compared with a traditional slab and less inconvenience. Other sustainable construction advantages include its performance,which means thinner slabs can be used without the need for any metal reinforcing and less energy consumption while being laid. Finally, it presents excellent resistance to surface abrasion, which avoids both the need for a protective render and costly maintenance work.}
When it comes to Class AA, Lafarge supplied concrete to build the fantastic Millau Bridge: http://www.lafarge.com/en/millau-viaduct-lafarge-cement-and-concrete-worlds-highest-bridge
I do not think that Eden has competitors.
