The sustainable ecology belongs to the most important issues today. In this field a use of recycled materials is of great interest to people. Consequently, incorporation of industrial waste, concrete and brick scraps and other rubbish into products for civil engineering use is very important. Certain results from experiments carried out in laboratory on standard samples are emerged in this paper. Since the material is not yet enough approved, three main targets are addressed. The first involves the behaviour of fiber reinforced concrete based on aggregates from various recycled material. Then the influence of distance among two or more fibers is observed. For completeness the results from shear tests are presented in the end of this paper., Jiřina Trčková and Petr Procházka., and Obsahuje bibliografii
To obtain the starting point for theoretical numerical computations the fibre reinforced concrete construction properties, adhesion of cement mixture with steel and polypropylene fibres and changes in its tension properties commensurate with number and weight percentage in the tested specimen were tested under laboratory conditions., Jiřina Trčková and Karel Řezba., and Obsahuje bibliografické odkazy
