PRESENT TRENDS IN THE MECHANICS OF CEMENT BASED FIBRE REINFORCED COMPOSITES

In the paper a few most representative directions of research in the title subject are examined and discussed from the viewpoint of their input to both the knowledge of composite materials behaviour and to the building practice. In fibre reinforced concretes (FRC) mechanics, the use of fracture energy absorption and crack propagation characteristics is observed. This approach is justified by inefficiency of classic notions to describe correctly the material behaviour. It appears that the ability to absorb energy and to control cracks is the most important advantage and it stimulates basic research. Intensive research programmes concern the application of FRC in building and civil engineering structures and such problems are considered as use of local components (i.e. natural fibres), low cost technologies and behaviour of FRC in various environmental conditions. The durability is another field of advanced research, oriented at explanation and control of accelerated degradation. The durability is particularly crucial for composites with nonmetalic fibres, i.e. glass or vegetal ones. There are also tests aimed at increase of strength and toughness by special techniques like polymer impregnation of matrices. The mechanical properties are considered as fundamental in all pratically oriented and economically motivated research programmes concerning FRC. (Author/TRRL)
