| Abstract. | The problem of mechanical behavior of deformable solid body structural applications is the focus of researchers in addressing testing of material challenges for the development and construction of building materials with the desired mechanical properties. Mechanical strength is the defining property of the material of construction. In turn, the most important parameter is the strength of the fracture toughness that characterizes the resistance of materials development of cracks and breakage. Study of strength involving physical representations about the nature and kinetics of the degradation of concrete under loading in the framework of its structural mechanics of composite material attracted the attention of researchers for its the importance of these, pragmatically and opportunity in the development of fracture mechanics approaches for creating composite high strength with good ductility fracture. The study gives reason to conclude that the prospect of structural materials, fracture mechanics approach in assessing the strength, energy and deformation criteria, the mechanical behaviour of cement composites. Using the method of acoustic emission study of fracture real time pilot opens up new possibilities for optimizing the structure of the cement composite. |
