By adding ultra fine fillers well dispersed between the dense packed cement particles a much denser cement paste will be developed. A significantly reduced amount of water is required to achieve the same good workability. A decreased w/c ratio and the very densely packed cement and ultra fine fillers will result in extreme fine pores between the cement particles which will give a much higher strength and a far better durability to the hardened matrix.

Due to the puzzolanic particles and the fine micro structure the final product will have impermeable properties and aggressive substances cannot penetrate the concrete. Resistance to chemicals, oil, chlorides etc. is significantly higher compared with traditional concrete

Due to the fact that the interface zone is less porous and consists of large amounts of small particles there is a much better bonding on the reinforcement. Bonding on 6mm steel bar is 4 – 5 times higher than in traditional quality concrete. Also fibers are extremely well anchored in the dense matrix. This makes it possible to use large amounts of small and smooth fibers like for instance 0.4 x 12.5 mm and 0.15 x 6 mm steel fibers. Up till 800 kg/m3 is possible.
