The intention of the book is twofold: first to summarize the most important mechanical properties of both steel – fibre – added concrete and steel – fibre – added reinforced concrete, second to describe the fracture process at the meso – scale in fibrous concrete using a novel discrete lattice model.

The book includes 6 Sections and is organized as follows. After a short introduction in Section 1, Section 2 summarizes the most important properties fibrous concrete. Section 3 includes detailed descriptions of experimental results on concrete and reinforced concrete with steel fibres from the scientific literature. Next. Theoretical models from the literature are shortly described (Section 4). In Section 5, our novel discrete lattice model is first outlined. Latter, boundary value problems involving fracture process in plain concrete (Section 5.1) and fibrous concrete (Section 5.2). Numerical results were qualitatively compared with corresponding laboratory tests. Finally, general conclusions from the research are enclosed (Section 6).
