Cracks in the concrete part of substructure are a problem in terms of penetration of water into the building. The best way is to prevent their development or support autogenous healing of concrete as much as possible. It is suitable to create many small specimens for research of crack evolution in various boundary conditions. TRC is applicable material for this research due to its compact dimensions and the ability to create a lot of cracks in relatively small area of the specimen. There are two basic methods how to create cracks in this material, tensile and bending loading. Each method provides different crack shapes.

Textile reinforced concrete with non-woven polypropylene fabric has variable utilization for non-load bearing structures. One of the possible uses is production of facade panels or protective layers in the interior of buildings. For that reason it is important to determine fire resistance of this material. There was examined behaviour of specimens exposed to temperature in range 100 – 650°C for times from 5 to 60 minutes. Weight loss of the specimens caused by heating was also measured. Regardless to the relatively high moisture of material, the effect of spalling didn’t occur.
