<p>A composite concrete with a low cement and fibre content having good mechanical properties as well as good impact, shock and projectile resistance properties. The concrete includes a) 70-85 wt.% of particles (A) having a particle size distribution of around 0.01/3 mm to 0.01/50 mm; b) 2-10 wt.% of particles (B) having a size of 0.01-1 mu m, i.e. from 10<-5> to 10<-3> mm; c) 3-20 wt.% of hydraulic binder; d) 0.1-3 wt.% of a dispersing or plasticising agent; (e) 0.05-8.5 wt.% of fibres; and (f) mixing water, said percentages being weight percentages based on the sum of the weights of components a) to d).</p>
