This paper presents a FE2 multi-scale framework for numerical modeling of the structural failure  of  heterogeneous  quasi-brittle  materials.  The  model  is  assessed  by  application  to cementitious  materials.  Using  the  Continuum  Strong  Discontinuity  Approach  (CSD),  innovative numerical  tools,  such  as  strain  injection  and  crack path  field  techniques,  provide  a  robust,  and mesh-size, mesh-bias and RVE-size objective, procedure to model crack onset and propagation at the macro-scale
